[0020] Bioreactor 103, in some embodiments, can further include at least two sensors (not shown) that measure multiple parameters, both physical and chemical, in the fluid medium and cells contained therein. In some embodiments, bioreactor 103 may further include at least three sensors. In some embodiments, bioreactor 103 may further include at least four sensors. In some embodiments, bioreactor 103 may further include five or more sensors. In some embodiments, reservoir chamber 107 of the exemplary bioreactor system can include at least one sensor that measures both physical and chemical parameters in the fluid medium contained therein.

In some embodiments, reservoir chamber 107 may further include at least four sensors. In some embodiments, reservoir chamber 107 may further include five or more sensors.
[0021] In some embodiments, the parameters sensed and measured (e.g., via sensors) in the exemplary bioreactor system can be selected from, but are not limited to, at least the following: cell concentration level, at least one nutrient level, at least one gas level, first culture medium liquid volume, first culture medium liquid pH level, first culture medium liquid temperature, or any combination thereof.
[0022] In some embodiments, the parameters are sensed, detected, measured, controlled, or any combination thereof. In some embodiments of the exemplary bioreactor system, these parameters are selected from, but not limited to, at least the following: a level of cell concentration contained in a bioreactor chamber, a flow rate of a fluid into a reservoir, a flow rate of the same or a different fluid into a bioreactor chamber, a volume of at least one fluid, a pH of at least one fluid, a temperature of at least one fluid, a level of dissolved oxygen in at least one fluid, a level of dissolved CO2 in at least one fluid, a level of HCO3 in at least one fluid, a level of nutrients in at least one fluid, and any combination thereof.

[0024] In some embodiments, at least three of the above parameters are detected by sensors in the bioreactor system. In some embodiments, at least three of the above parameters are measured by the bioreactor system. In some embodiments, at least three of the above parameters are controllable by the configuration of the bioreactor system (e.g., via a controller controlling the fluid circuitry). In some embodiments, the exemplary bioreactor system is capable of controlling the sensed and measured parameters to a predetermined set point or predetermined range of that measured value. In some embodiments, the exemplary bioreactor system is capable of controlling one to five parameters. In some embodiments, the exemplary bioreactor system is capable of controlling five to ten parameters. In some embodiments, the exemplary bioreactor is capable of controlling at least three parameters simultaneously, substantially simultaneously, or the control inputs for multiple parameters are not simultaneous, but activation of the fluid circuitry within the bioreactor system based on the control inputs affects changes to these parameters simultaneously.
[0025] 1A, the fluid circuit may include a fluid circuit 109 in which a first pump 109a extends from a reservoir chamber 107 into a bioreactor 103 and a second pump 109b may extend from at least one bioreactor into at least one reservoir. In some embodiments, an inlet 111 of the reservoir chamber 107 can be used to input materials for bioreactor culture. In some embodiments, an outlet 105 of the reservoir chamber 107 can be used to remove spent waste, medium, or any combination thereof.
[0026] In some embodiments, the configuration of the fluid circuit (e.g., pump system) 109 in the exemplary bioreactor system causes the reservoir chamber 107 to control all inputs to the bioreactor via the controller 106 or a component thereof, e.g., a processor. In some embodiments, the reservoir chamber 107 can use its own pump system in conjunction with the reservoir to control parameters of the biological reaction or cells and first fluid medium within the bioreactor.
[0027] In some embodiments, the exemplary bioreactor system can measure at least one parameter in the bioreactor and use that measurement to control that parameter by altering a parameter in the reservoir. In some embodiments of the exemplary bioreactor system, the measurement of the parameter is made in the bioreactor 103 and controlled by altering the parameter in the reservoir chamber 107. In some embodiments, the exemplary bioreactor system can alter the parameter in the reservoir to affect a change in the parameter in the bioreactor 103 using the pump system 109. In some embodiments of the exemplary bioreactor system, the measurement of the parameter is made in the bioreactor 103 and controlled solely by altering the parameter in the reservoir chamber 107. For example, in some embodiments, the pH level of the first medium in the bioreactor can be controlled to a range of 6.5 pH to 7.5 pH by controlling the reservoir fluid medium range to a range of 5 pH to 8 pH while controlling other set points. In some embodiments, the following parameters introduced by the pump system 109 can also be measured by sensors in either the bioreactor or the reservoir: the flow rate of bioreactor liquid to the reservoir, the flow rate of liquid from the reservoir to the bioreactor, or any combination thereof.
[0028] In some embodiments, the exemplary bioreactor system may require more medium and nutrients and larger culture volumes. In some embodiments, the exemplary bioreactor system may allow for the volume of liquid medium within the bioreactor to be changed, allowing for the addition of additional medium without the need to transfer the cells to a separate vessel.
[0029] In some embodiments, suitable controllers for controlling the flow of gases and / or fluids can include, but are not limited to, one or more valves and / or one or more pumps, for example, as shown herein.
[0030] In some embodiments, the exemplary bioreactor system can use a pump system to regulate the volume of medium contained in the bioreactor.
[0031] In some embodiments, the pump system may remove at least a portion of the liquid from the bioreactor, add at least a portion of the liquid in the reservoir to the liquid in the bioreactor, or any combination thereof, such that the volume of the liquid in the bioreactor is adjustable.
[0032] In some embodiments, the exemplary bioreactor system 100B may alternate between culture modes, as described in more detail below. In some embodiments, alternating between culture modes may facilitate the ability of the bioreactor system 100B to simultaneously control multiple parameters.
[0033] In some embodiments, the system includes a batch culture mode. In some embodiments, the exemplary bioreactor system can operate in a batch culture mode by having the reservoir chamber 107 receive a predetermined amount of medium and pumping the medium into the bioreactor. The bioreactor can then discharge waste products through the outlet 105.
[0034] In some embodiments, the system includes a fed-batch culture mode. In some embodiments, the exemplary bioreactor system can process the fed-batch mode by having the reservoir chamber 107 receive a predetermined amount of medium and pumping the medium into the bioreactor. In some embodiments, the process is then repeated for a predetermined amount of time. In some embodiments, the predetermined amount of time is between 1 day and 2 months. In some embodiments, the predetermined amount of time is between 2 days and 4 months.
[0035] In some embodiments, the system includes a perfusion culture mode. In some embodiments, the exemplary bioreactor system can handle the perfusion culture mode by having the reservoir chamber 107 receive medium through the inlet 111 and pumping this same medium into the bioreactor. Sensors detect parameters such that only a significant amount of waste is removed through the bioreactor outlet 105.
[0036] In some embodiments, the system includes a recirculation mode. In some embodiments, the exemplary bioreactor system can handle a recirculation culture mode with a first pump 109a continuously pumping liquid medium from a reservoir to the bioreactor and a second pump 109b continuously pumping liquid medium from the bioreactor to the reservoir.
[0037] 1C is a block diagram of a controller 106 that controls bioreactor systems 100A and 100B according to one or more embodiments of the present disclosure. Controller 106 may include a processor 200, non-transitory memory 210, input and / or output devices 215, communication circuitry 220, interface circuitry 225, and / or control circuitry 230. Processor 200 may execute a cell culture control machine learning model 205 and an image processing module 204. Processor 200 may receive sensor data from multiple sensors 104a, 104b, 104c via interface circuitry 225 and generate commands to digitally control devices via control circuitry 230.
[0038] 1A (e.g., an imaging camera) of any suitable type, can be positioned anywhere in and / or around the bioreactor chamber and / or reservoir to output image data of an image of any portion of the bioreactor, including generating images of a cell culture growing in the bioreactor for analysis by the controller 106. Images of the cell culture via the interface circuit 225 can be analyzed and processed by the image processing module 204.
[0039] In some embodiments, an automated cell counter (not shown) may automatically microsample the cell culture by any suitable method to determine the number of cells in the cell culture. At least one imaging camera may be attached to the microscope to image the cells in the microsample. The images are analyzed by the image processing module 204 to determine the types and numbers of different cells in the cell culture at time points either set by the operator or by control of the cell culture control machine learning model 205.
[0040] In some embodiments, the cell analyzer can be used to test activity and / or cell phenotype within the cell culture in the bioreactor chamber.
[0041] In some embodiments, the input / output devices 215 of the controller 106 may include any display device known in the art for displaying processed results and values of any sensed parameters to an operator or user of the system 100. The controller 106 may also include one or more user interface devices (e.g., without limitation, a mouse, light pen, pointing device, keyboard, touch-sensitive screen, or any other input device known in the art) used by a user or operator of the bioreactor systems 100A and 100B to input data and / or appropriate commands to the controller 106. For example, a user may control the bioreactor 103 by inputting appropriate commands to the controller 106 via one or more user interface devices, which in turn causes the controller 106 to send appropriate control signals to any of the bioreactor fluid controls via the control circuitry 230. The user may input any appropriate parameters via the one or more user interface devices as inputs to the MLM 205 and to view any outputs generated from the MLM 205 on a display.
[0042] In some embodiments, computer-controlled sensor and / or electronic control components of the bioreactor system that can be monitored and / or controlled via interface circuit 225 and / or via control circuit 230 to sample multiple sensors can include, for example, but are not limited to: (1) An agitator or stirrer that keeps the contents of the bioreactor mixed and ensures proper distribution of nutrients, oxygen, and heat. Different types of impellers (paddles, turbines) can be used depending on the specific needs of the culture. (2) A temperature control system that maintains the optimal temperature for cell growth and activity. Bioreactors can use heating jackets, internal coils, and / or even water baths to achieve this. (3) A pH control system that can use any suitable pH sensor and / or dosing system to adjust the acidity or alkalinity of the culture medium to maintain it within a desired pH range. (4) Aeration and aeration to oxygenate the culture. Some bioreactors can use spargers to introduce gas bubbles, while others rely on agitation or membrane technology. Other gases, such as CO2, can also be controlled. (5) A nutrient inlet-outlet that can provide fresh nutrients to the culture and remove waste materials that can be fed into the bioreactor. This can be done via computer-controlled ports and / or integrated tubing. (6) Sensors and / or analytical instruments that monitor critical parameters such as, for example, but not limited to, oxygen levels, pH, and / or cell density. The bioreactor 103 can include any suitable variety of sensors and / or probes coupled to provide real-time data. (7) A computer-controlled sampling port to take samples of the culture for analysis without interrupting the process. (8) A sterilization system to keep the bioreactor clean and free of contamination. Steam sterilization may be used. Pre-sterilized single-use systems may also be used. (9) A computer-controlled sparger and / or air inlet that introduces gases such as air or oxygen directly into the culture medium via a sparger and / or diffuser. (10) A computer-controlled foaming system to manage excessive foaming that may impede mixing and oxygen transfer. Anti-foam agents and / or mechanical devices may be deployed by the computer-controlled foaming system to manage this.
[0043] The embodiment shown in Figure 1A depicts basic components of a bioreactor system solely for conceptual clarity in describing how machine learning models can monitor and / or control cell growth by processing sensor data and / or controlling a bioreactor system's controller. The bioreactor 103 can include any suitable form factor and any suitable number of additional elements (not shown in Figure 1A) to provide optimal and adaptive culture, such as, for example, but not limited to, the bioreactor system 100A and 100B elements shown in Figures 1A-1C.

As used herein, in some embodiments, the terms "cell" and "microorganism" may be used interchangeably, all having the same meaning and quality.
[0050] In some embodiments, bioreactor 103 may include one or more sensors 104a, 104b, and 104c, which may be suitably linked and / or connected to controller 106 via interface circuit 225 to monitor and / or regulate various physical and / or chemical parameters within the growth medium (e.g., temperature, pH, glucose concentration, dissolved oxygen concentration, concentration of dissolved carbon dioxide or HCO ions, concentration of lactate, and ionic strength, etc.) in the bioreactor and / or bioreactor headspace and / or growth medium, which may all be sensed, monitored, and controlled at fluid reservoirs and / or various inlet or outlet ports connectable to the bioreactor. In some embodiments, the sensors may detect products synthesized by cells or microorganisms grown in the bioreactor. In some embodiments, control of some of the above features may require mixing of the growth medium, which may be provided at the fluid reservoirs.
[0051] In some embodiments, the computer-based system of the disclosed bioreactor controls and monitors metabolic and environmental factors such as oxygen, pH, glucose, lactate, glutamine, glutamate, etc. For example, the computer-based system of the disclosed bioreactor is applied to different biological materials, such as cells, that consume or produce O at different rates, depending on their state. Furthermore, the computer-based system of the disclosed bioreactor may be applied to different types of cells that consume or produce O differently.
[0052] In some embodiments, the computer-based system of the disclosed bioreactor may be applied to non-activated T cells, which may consume small amounts of O2 and glucose and produce very small amounts of lactate. When the T cells are subsequently activated, they not only begin to proliferate but also change their metabolism, shifting their energy cycle from O2 to lactate, thereby altering the consumption rates of all of the above, resulting in increased lactate secretion per cell. Such activity depends on the level of activation / stimulation achieved by adding antibodies to the culture medium. Within a few days, depending on the stimulation level, the T cells may slow down, return to their natural state, or become exhausted (reduced Lac production per cell). In some embodiments, the computer-based system of the disclosed bioreactor measures and controls, for example, bacterial contamination, when the consumption rates of O2 and glucose increase dramatically.
[0053] In some embodiments, the computer-based system of the disclosed bioreactor is applied to T cells as they are introduced into a target, which activates the T cells and then alters their consumption and production rates.
[0054] In some embodiments, the computer-based system of the bioreactor of the present disclosure applies online monitoring to identify such changes and predict the state of the cells with respect to at least one of subsequent activation, transduction, contamination in culture, differentiation, cell death, exhaustion and / or even phenotype and killing potential.
[0055] In some embodiments, the computer-based system of the disclosed bioreactor is applied to primary cells, such as, but not limited to, mesenchymal stem cells. When stimulated to proliferate until a surface is covered (confluence) and inhibited by contact inhibition, mesenchymal stem cells change their metabolism. These primary cells then become activated, not only beginning to proliferate, but also changing their metabolism and shifting their energy cycle from O2 to lactate, altering the consumption rates of all of the above, resulting in increased lactate secretion per cell. Such activity depends on the level of activation / stimulation achieved by adding antibodies to the culture medium. Within a few days, depending on the stimulation level, these primary cells slow down and either return to their natural state or become exhausted (reduced Lac production per cell). In some embodiments, the computer-based system of the disclosed bioreactor measures and controls, for example, bacterial contamination, as well as dramatic increases in O2 and glucose consumption rates.
[0056] In some embodiments, the computer-based system of the disclosed bioreactor may be applied to primary cells when they are introduced into a target that activates these primary cells and subsequently alters their consumption and production rates.
[0057] In some embodiments, the computer-based system of the bioreactor of the present disclosure may apply online monitoring to identify such changes and predict the state of the cells with respect to at least one of subsequent activation, transduction, contamination in culture, differentiation, cell death, exhaustion and / or even phenotype and killing potential.
[0058] In some embodiments, the culture chamber (e.g., assay) can include multiple sensors 104a, 104b, and 104c similar to those in bioreactor systems 100A and 100B described above. Multiple cells can be removed from bioreactor 103 and introduced into the culture chamber to measure the state of the cells, which can be monitored by cell culture control machine learning model 205.
[0059] In some embodiments, the computer-based system of the disclosed bioreactor can be applied to cells (e.g., stem cells), where the cells are stimulated to grow until they differentiate, and then identify when the cells differentiate and not only begin to proliferate but also change their metabolism, shifting from the O2 energy cycle to lactate, thus changing the consumption rates of all of the above, meaning more lactate secretion per cell. In some embodiments, the computer-based system of the disclosed bioreactor measures and controls when, for example, bacterial contamination, O2 and glucose consumption rates dramatically increase.
[0060] In some embodiments, the computer-based system of the bioreactor of the present disclosure can be applied as an online QC to ensure sterility. In some embodiments, the computer-based system of the bioreactor of the present disclosure can be applied to predict when cells will be ready to move to different stages of the culture or to intervene during the culture to reactivate them.
[0061] In some embodiments, the computer-based systems of the bioreactors of the present disclosure can be applied to measure and control not only cell metabolic changes but also "time courses" (e.g., parametric changes over time) and / or gradients and / or differences (e.g., deltas) between parameter value points to predict outcomes.
[0062] FIG. 2 illustrates sensor measurement output data from a bioreactor according to one or more embodiments of the present disclosure. The top trace is the O2 level within the cone. The bottom trace is the circulation rate of the pump feeding the cone. The 40% marker is the set point (SP) for activating perfusion. Points A-B are unactivated cells showing stable oxygen consumption. Point C is the time at which activation reagents can be added. Points D-E can be where cells consume significantly more oxygen. Between points E and G is where viruses are introduced for genetic manipulation. Points I-J are where the pump begins to operate. The processor 200 can now calculate the slope. In other embodiments, the pump can be stopped for X minutes and the slope measured again, where X is any suitable positive number.
[0063] Figure 3 is a graph of glucose (Glu) and lactate (Lac) levels obtained from the same data (e.g., the same run) as Figure 2. However, the slope of Glu varies differently than Lac. In some embodiments, the computer-based system of the disclosed bioreactor can be adapted so that results can be correlated to the difference (e.g., delta) between the slopes of one parameter for the same parameter at different time points and / or to correlate changes between the differences (deltas) of different parameters. In this way, a time course concept can be used to examine and compare changes in consumption over an X amount of time compared to the slope of a later stage, where X is any suitable positive number.
[0064] In some embodiments, processor 200 evaluates the slope of A / B where A=GLU and B=LAC is approximately flat, however, once cells in cell culture can be activated, the slope of A / B can become very steep.
[0065] In some embodiments, the computer-based system of the bioreactor of the present disclosure can be applied as shown in Figure 4. Figure 4 shows that increasing the O2 pump rate correlates with increasing dissolved O2 (DO) in the cell culture, so the cells can still be activated and grow.
[0066] In some embodiments, the computer-based system of the disclosed bioreactor can be applied as shown in FIG. 5. FIG. 5 is a graph of both dissolved oxygen (DO) levels and O2 pump speed versus time. The graph also shows the DO setpoint value. Inside the box, the pump is at its first maximum event on day 5, then at its second maximum event again on day 8, when the cells consume more O2, then less, and then switch back on on day 9. Cells change metabolism, which correlates with changes in phenotype or cell population during growth. Therefore, changes in consumption / secretion of factors and metabolic factors are used to correlate state and / or change culture conditions. In other words, this metabolic change correlates with phenotypic changes in cell state or phenotypic protein changes in cells, which are linked to phenotype and activity, and then to predictions of number and state.
[0067] In some embodiments, the computer-based system of the bioreactor of the present disclosure can be applied as shown in Figure 7. Figure 7 shows the change in lactate levels as a function of time (days) in an exemplary run of Lac.
[0068] In some embodiments, the computer-based system of the bioreactor of the present disclosure can be used to correlate multi-parameter changes / gradients (O2, pH, Glu, Lac levels) at different time points to predict the state of the culture and use it in several different applications.
[0069] In some embodiments, the computer-based system of the bioreactor of the present disclosure can apply graphs of bacterially contaminated runs as supporting data and correlate desired results based on this data.
[0070] In some embodiments, the computer-based system of the bioreactor of the present disclosure can apply the assistance data to result in a lower and / or higher activation rate or percentage of activated cells.
[0071] In some embodiments, the computer-based system of the bioreactor of the present disclosure can apply supporting data to indicate the effect of adding an activation reagent after cell growth has slowed.
[0072] In some embodiments, the computer-based system of the bioreactor of the present disclosure can apply supporting data of samples of cells at different stages to determine correlations with phenotypes.
[0073] In some embodiments, the computer-based system of the bioreactor of the present disclosure can apply supporting data to indicate killing activity due to metabolic alterations.
[0074] In some embodiments, a cancer drug resistance / activity assay that uses a metabolic change readout to test anti-cancer drugs can be used to determine whether a targeted drug stops or slows tissue growth by measuring metabolic changes and correlating drug resistance and / or activity assays.
[0075] 6 is a graph showing oxygen consumption levels (DO) versus run time, according to one or more embodiments of the present invention. The graph shows the correlation from activation time (left arrow) to run time with changes in oxygen consumption during the run for multiple samples. As oxygen increases (right arrow), the process slows down due to metabolic changes, not due to cell death. Viability is 96%.
[0076] 7 is a graph showing lactate accumulation rate versus run time, according to one or more embodiments of the present invention. The graph shows the correlation from activation time (arrow) across run time with changes in lactate accumulation rate during running.
[0077] 8 is a graph showing glucose consumption rate versus run time, according to one or more embodiments of the present invention. The graph shows the correlation from activation time (arrow) across run time with changes in glucose consumption rate during run.
[0078] In general, those skilled in the art know that a machine learning model can be trained using a training dataset having specific input data features and specific output data features to match a machine learning model that outputs specific output data features within a desired prediction accuracy in response to the input of specific input data features. In other words, the trained machine learning model maps specific input data features to specific output data features. As a result, without the above-mentioned detailed specificity of (1) a specific machine learning model and (2) a specific training dataset with specific inputs and outputs, any training process cannot achieve convergence that provides prediction accuracy.
[0079] In some embodiments, the exemplary parameter correlations over time shown in Figures 6-8 across thousands of cell culture runs for thousands of subjects (e.g., patients) can be utilized in constructing a dataset capturing multiparametric time-dependent correlations between multiple sensor parameters and multiple cell culture growth parameters. These specific input features in the dataset can include a desired cell growth configuration (e.g., initialization and definition files) and sensor data from each of multiple sensors (e.g., different sensor types, such as pH, DO, and temperature) at different sampling times, as well as image data. The desired cell growth configuration can include at least one cell culture growth parameter from the multiple cell culture growth parameters and at least one desired range for each of the multiple sensor parameters measured by the multiple sensors at predetermined time intervals for each of the at least one cell culture growth parameter during cell culture growth. In other embodiments, the at least one desired range can include a single parametric set point.
[0080] Particular output features in the dataset may include multiple output data features and / or output features related to cell culture parameter predictions, which may include multiple cell culture control actions such as, but not limited to, a display, sending at least one control circuit command (e.g., a digital command to the control circuit 230) to one or more controllers to control gas levels and / or liquid flow in the bioreactor chamber, and / or to remove waste from the liquid medium.
[0081] 9A-9E are tables illustrating different parameter features whose values can be used to construct a dataset for training at least one machine learning model. These tables may relate to, but are not limited to, the above-described bioreactor chamber embodiment of a conical-shaped bioreactor chamber separated by a perforated barrier into two subchambers (a conical subchamber for cell growth and a medium subchamber). Each subchamber may have its own sensors and computer controller that control gas and / or fluid flow within the subchamber.
[0082] FIG. 9A is a table showing sensor data levels measured in the cone and media subchambers at predetermined sampling times during a cell growth cycle, according to one or more embodiments of the present disclosure.
[0083] FIG. 9B illustrates correlations between measured sensor data and cell culture growth parameters, according to one or more embodiments of the present disclosure. Time-dependent multivariate correlations between measured sensor data in the cone and medium at a given sampling time can be used to determine cell culture growth parameters that can be derived from these time-dependent correlations. For example, from FIG. 9B , correlations between measured cone DO, pH, and lactate levels measured by sensors at different sampling times (from the start time of the cell growth process) can be used to monitor cell seeding. Similarly, correlations between cone DO levels, medium lactate levels, medium glucose levels, medium glutamine levels, and medium glutamate levels measured at different sampling times can be used to determine cell phenotype and cell harvest. These correlations can be used to build datasets for training machine learning models across multiple cell samples collected from multiple subjects (e.g., patients) for multiple sampling times from the cell run start time to the cell run end time.
[0084] In some embodiments, correlations between two or more parameters (e.g., oxygen / lactate / glucose consumption) can represent cellular stages after activation, such as when glucose slows, lactate increases, and oxygen also increases, and parameter correlations can be based on measuring the difference in slopes. For example, at day 11, metabolism changes and the cells are no longer activated, as exemplified by changes in the profiles of all three parameters.
[0085] In some embodiments, for example, a data set capturing correlations between various parameters over time detected and monitored in real time by sensors 104a, 104b, and 104c can be used to train cell culture control machine learning model 205 to predict cell states and / or outcomes at different stages of the expansion process. As a result, these correlations between cell states and particular measured parameters can provide future estimates related to cell quantity, cell health, and other factors. Furthermore, if a particular parameter at a particular point in the expansion process is determined to be likely to result in unhealthy cells at a particular future time and not yield good cells for harvest, the MLM may, for example, output a warning to halt the particular cell expansion process and / or output a set of commands via control circuitry that automatically controls bioreactor fluid controls and / or temperature controllers to alter system parameters to place cell growth on a different path toward good cell health so that cells can be harvested in the future.
[0086] In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least two and three parameters. In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least three and four parameters. In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least four and six parameters. In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least six and ten parameters. In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least ten parameters. In some embodiments, at least one cell culture control MLM205 may be trained using a parametric correlation between at least 50 parameters.
[0087] 9C is a table illustrating desired cell growth run configuration file parameters according to one or more embodiments of the present disclosure. These parameters can be entered into the system when initiating a cell growth run (e.g., an initialization configuration data file). These parameters can include, for example, performing an action regardless of machine learning model output. Furthermore, these parameters can be used in constructing a dataset for training at least one cell culture control MLM 205.
[0088] 9D is a table showing input data features for a conical bioreactor chamber according to one or more embodiments of the present disclosure. The input data features may include cell culture start time, sampling time after cell culture start time, cone and / or medium gas parameters, cone and / or medium parameter levels (DO, pH, CO, O, N, glucose, lactate, glutamine, glutamate (similar to FIG. 9A)), cell count and / or image data from medium and / or cone images.
[0089] In some embodiments, the computer-based system of the bioreactor of the present disclosure can be used to construct multiple training data sets based on correlations between different gradients of different parameters, such as, but not limited to, O2, Glu, Lac, pH, and cellular and system parameters at different times t, where t=0 can be the start of the growth process that predicts the state of cells and their growth process at a future time. The at least one cell culture control machine learning model 205 can be trained to output one or more of the following cell culture parameter predictions based on monitoring the different parameters: 1. Prediction of activation status and the number or percentage of activated cells 2. Prediction of cell number 3. Prediction of cell proliferation or differentiation state 4.Prediction of cell differentiation 5. Phenotype (activation / inactivation) prediction 6. Predict populations and subpopulations within a culture that behave metabolically differently due to stimuli such as activation, heat shock, stress, and hypoxia. 7. Prediction of contamination (bacteria or fungi) 8. Predicting or even testing functionality (will T cells respond to and kill the target) 9. Predicting when cells may change and require intervention such as reactivation or transfer to a different medium. 10. Food contamination prediction: This can be used in other industries such as food to see contamination. 11. Prediction of quality control (QC) tests that can be performed within the devices as they grow, including phenotype, activity, and sterility. The QC concept uses indirect measurements and correlations to test activity and phenotype. 12. Predictions for the identification of cancer cells in culture by metabolic consumption. 13. Prediction of the identified activity of drugs such as antibiotics or anticancer drugs based on changes in consumption. 14. Prediction of drug resistance and activity in cancer cells - for example, metabolic changes due to the addition of anticancer drugs.
[0090] 9E is a table illustrating output data features of a conical bioreactor chamber associated with culture for cell parameter prediction, according to one or more embodiments of the present disclosure. The input data features of FIG. 9D combined with the output data features of FIG. 9E can be used to generate a dataset across multiple cell samples taken from multiple subjects at different sampling times to generate a dataset with millions of data features for training at least one cell culture control MLM 205. The predicted values of the output data features shown in FIG. 9E can be based on at least one cell culture control MLM 205 trained on the measurement data from FIG. 9B.
[0091] In some embodiments, the at least one cell culture control MLM 205 may output predicted values of a particular output data feature, such as that shown in FIG. 9E, with a prediction accuracy of 0.1-1% for measurements in the dataset, depending on the type of prediction parameter selected. In other embodiments, the at least one cell culture control MLM 205 may output predicted values of a particular output data feature, such as that shown in FIG. 9E, with a prediction accuracy of 1-10% for measurements in the dataset, depending on the type of prediction parameter selected. In yet other embodiments, the at least one cell culture control MLM 205 may output predicted values of a particular output data feature, such as that shown in FIG. 9E, with a prediction accuracy of 10-30% for measurements in the dataset, depending on the type of prediction parameter selected.
[0092] In some embodiments, the different predictions or predicted results shown in Figure 9E can be in the form of flags (Yes, Contaminated, or No Contaminated) based on input sensor level readings over multiple sampling times and the correlations between them. In other embodiments, the predictions can include predicted values and / or predicted ranges for each measurement-based value of the output metric at future times based on correlations such as those shown in Figures 2-8 and later figures (Figures 10-16A and 16B).
[0093] 9F is a table of output data characteristics from at least one cell culture control MLM 205 sending output commands to control circuit 230, according to one or more embodiments of the present disclosure. The at least one control circuit command can be used by control circuit 230 to automatically control gas and / or liquid flow rate changes and / or waste removal within the bioreactor chambers.
[0094] In some embodiments, the at least one control circuit command can cause at least one cell culture prediction (eg, any of the predictions in FIG. 9E) to be displayed on a display.
[0095] In some embodiments, the at least one control circuit command can control a gas regulator that varies the gas level in the bioreactor chamber.
[0096] In some embodiments, the at least one control circuit command can control a device that controls liquid flow of the nutrient fluid from the reservoir chamber to the bioreactor chamber.
[0097] In some embodiments, the at least one control circuit command can control, for example, a device coupled to the bioreactor chamber to remove waste products from the liquid medium.
[0098] In some embodiments, the at least one cell culture control MLM 205 may be further trained to output automated actions in the bioreactor system 100A and / or 100B, such as in the following scenarios:
[0099] In some embodiments, stem cells may be grown within the bioreactor on a surface or in suspension. Once the stem cells reach confluence or a desired density, their growth may slow or cease consumption, which may in turn alter the rate of glucose, oxygen, and / or lactate accumulation and alter the ratios between them. At this point, at least one cell culture control MLM205 can cause the system to add cytokines and / or differentiation factors to the cell culture to induce differentiation toward a desired phenotype.
[0100] In some embodiments, cells such as mesenchymal stem cells can secrete extracellular vesicles called exosomes. Seeded cells in a bioreactor can grow until they reach a specific density or activity, defined by the ratio of metabolic parameters. Once a specific density is reached, the medium can be automatically changed by at least one control command output from the at least one cell culture control MLM 205 to the controller, changing the medium from a rich growth support medium to a recovery medium, which may be serum-free, to ensure a high yield of harvested exosomes. The same scenario can occur for vaccine, virus, protein, and / or antibody secretion, and yield can be optimized using at least one control command output from the at least one cell culture control MLM 205.
[0101] In some embodiments, mesenchymal stem cells may be grown to confluence, and then oxygen levels within the system may be automatically altered by at least one control command output from at least one cell culture control MLM 205 to control the device to prime the cells to a hypoxic state that has been shown to result in stronger angiogenic activity.
[0102] In some embodiments, cell contamination can be identified by measurements taken over consecutive time samples that show correlations, such as a sudden change in pH, a sudden drop in DO, glucose, lactate, pressure, and / or a change in a color parameter of the liquid medium (e.g., the liquid medium may become cloudy). Data from thousands of cell samples terminated prematurely due to contamination can be used to train at least one cell culture control MLM205 to identify cell contamination. Thus, when real-time measurement sensor and / or image data at a predetermined sampling time for a cell culture can be input into at least one cell culture control MLM205 trained with these correlations, the at least one cell culture control MLM205 can output a prediction that the cell culture is contaminated and generate a command to display a warning or sound an alarm to the bioreactor system operator.
[0103] In some embodiments, the at least one cell culture control MLM 205 may be further trained to generate control circuit commands that perform automatic system corrections by initiating changes in gas and / or liquid levels within the bioreactor chamber, as shown in FIG. 9E. For example, if a decrease in DO or a change in, for example, lactate formation rate, is observed over successive time samples, indicating that cells may not be responding as expected, the at least one cell culture control MLM 205 may detect this and output a command to the controller to automatically introduce interleukin-2 (e.g., IL-2) into the cell sample, for example, to increase T cell proliferation. The at least one cell culture control MLM 205 may automatically monitor the administration schedule of IL-2 over time to prevent T cell exhaustion and optimize cell stimulation.
[0104] The cell culture control machine learning model 205 may include types of machine learning models that may include, but are not limited to, decision trees, boosting, support vector machines, neural networks, nearest neighbor algorithms, naive Bayes, bagging, random forests, etc. In some embodiments, optionally in combination with any of the above or below embodiments, the exemplary neural network technique may be one of, but is not limited to, a feedforward neural network, a radial basis function network, a recurrent neural network, a convolutional network (e.g., U-net), or other suitable network.
[0105] In some embodiments, optionally in combination with any of the embodiments described above or below, an exemplary implementation of a neural network may be performed as follows. i) Define the neural network architecture / model, ii) forwarding the input data to an exemplary neural network model; iii) incrementally learning example models; iv) determining the accuracy of a certain number of time steps; v) using the example trained model to process newly received input data; vi) Optionally and in parallel, continue training the example trained model at predetermined intervals.
[0106] In some embodiments, optionally in combination with any of the above or below embodiments, the exemplary trained neural network model (e.g., MLM 205) may specify the neural network by at least a neural network topology, a set of activation functions, and connection weights. For example, the topology of the neural network may include the configuration of nodes in the neural network and the connections between such nodes. In some embodiments, optionally in combination with any of the above or below embodiments, the exemplary trained neural network model may also be specified to include other parameters, including, but not limited to, a bias value / function and / or an aggregation function. For example, the activation function of a node may be a step function, a sine function, a continuous or piecewise linear function, a sigmoid function, a hyperbolic tangent function, or any other type of mathematical function that represents a threshold at which the node is activated. In some embodiments, optionally in combination with any of the above or below embodiments, the exemplary aggregation function may be a mathematical function that combines (e.g., sum, product, etc.) input signals to the node. In some embodiments, optionally in combination with any of the above or below embodiments, the output of the exemplary aggregation function may be used as an input to the exemplary activation function. In some embodiments, optionally in combination with any of the embodiments described above or below, the bias may be a constant value or function that may be used by the aggregation function and / or activation function to make a node more or less likely to be activated.
[0107] In some embodiments, the bioreactor system 100 can automatically construct datasets using data collected from cell sample runs and measurement data. These datasets can be used by the controller 106 to automatically retrain at least one cell culture control machine learning model 205. Optionally or alternatively, datasets from multiple bioreactor systems 100 with cell cultures from multiple subjects (e.g., patients) respectively can be transmitted via communications circuitry 220 to a backend cloud server (not shown) to retrain at least one cell culture control machine learning model 205 using datasets from different bioreactor systems.
[0108] In some embodiments, at least one cell culture control MLM 205 may include two machine learning models, where a first machine learning model may be trained to map input data including sensor data from each of a plurality of sensors to output data including predictive cell culture parameters, and a second machine learning model may map the predictive cell culture parameters to a plurality of control circuit commands to automatically control gas and / or liquid flow within a bioreactor chamber.
[0109] In some embodiments, metabolic analysis, such as correlating changes in the ratios of DO, glucose, lactate, glutamine, and / or glutamate over time during cell culture growth, can identify metabolic changes that may be important for the differentiation and functionality of T cells (effector and regulatory cells). For example, effector T cells may increase their glycolysis levels upon activation. Measurement of changes in glucose consumption levels and lactate production rates can be important indicators of proliferation progression. Regulatory T cells may have different metabolic preferences, such as fatty acid oxidation and mitochondrial metabolism, which may be more prevalent in regulatory T cells than in effector T cells. Glutamine metabolism may be involved in regulating the expansion and function of regulatory T cells. Glutamine uptake can be significantly enhanced upon TCR stimulation in T lymphocytes and may be important for their proliferation and cytokine production.
[0110] 10 is a graph showing phenotype prediction using metabolic sensing, according to one or more embodiments of the present disclosure. At day 1 (region A), a mixture of PBMCs (peripheral blood mononuclear cells) is deactivated and shows a steep O2 consumption slope at marker A1. A large subset of cells, such as non-T cells, has died, as indicated by lower O2 consumption at marker A2. When T cells are activated at day 6 (region B), O2 consumption increases as a result of proliferation, and the O2 pump rate increases, maintaining a substantially flat DO level as T cells grow at higher O2 consumption (region C). (The top trace is O2 supply, and the bottom trace is O2 level.)
[0111] 11 is a graph showing lactate formation according to one or more embodiments of the present disclosure. Prior to T cell activation on day 6 (region A), lactate formation is minimal. At day 6 (region B), activated T cells begin to produce lactate and the rate of lactate formation increases. At day 11 (region C), T cells change their phenotype to inactivated and the rate of lactate formation decreases.
[0112] 12 is a graph showing glucose consumption according to one or more embodiments of the present disclosure. In region A, minimal glucose consumption is observed (higher DO levels) as there is no proliferation. In region B, T cells are activated and begin to proliferate, resulting in increased glucose consumption as DO levels decrease. In region C, the T cell phenotype changes from activated to inactivated, resulting in higher glucose consumption as DO levels decrease further.
[0113] 13 is a graph showing dissolved oxygen and O2 pump rate in a cone according to one or more embodiments of the present disclosure. In pre-activation region A, oxygen consumption increases slightly and the O2 pump rate is low and fairly flat. In post-activation region B, medium is added to the cone, DO levels spike at about 60%, and oxygen consumption increases and the O2 pump rate is higher when the medium is changed around day 13.
[0114] 14 is a graph showing lactate formation rate (LFR) and glucose formation rate (GCR) according to one or more embodiments of the present disclosure. In pre-activation region A, there is a slight increase in LFR and GCR. In activation region B, lactate levels increase and glucose levels decrease for each cell, especially as the medium is changed.
[0115] FIG. 15 is a graph showing the LFR / GCR ratio according to one or more embodiments of the present disclosure. As the culture is consumed, the population may change, and the ratio of glucose to lactate may change with more activated cells. Thus, FIGS. 13-15 show that each parameter responds differently during a run. The ratio changes, indicating a change in the state of multiple cells. FIG. 15 shows that the LFR / GCR ratio nearly reaches the theoretical ratio value of 2, indicating that nearly 100% of the cells may be in a proliferative state.
[0116] 16A and 16B show two embodiments of transduction efficiency according to one or more embodiments of the present disclosure. Following cell transduction, perfusion begins 24 hours later, and the dissolved oxygen percentage may increase to a higher value if the transduction efficiency is low, but remains at a lower percentage if the transduction efficiency is high. When the DO falls below the DO set point (SP), the O2 pump may be activated, causing an increase in DO (day 3). Furthermore, the pump speed and DO level may show a higher rate of increase if the transduction efficiency is low compared to if the transduction efficiency is high. In FIG. 16B, there is a small population of activated cells, as evidenced by the drop in DO.
