Temporal Genetic Vectors for Precise Cell State Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manipulating and studying cells are limited by the need for large-scale cultures and lack of precise, temporal control over genetic events, making it difficult to efficiently direct cells to specific states or remove specific cell types in mixed populations.
Innovation Solution
The use of vectors with temporal encoding of multiplex genetic effectors, combined with image-guided laser ablation and optical processing, allows for precise control over cell growth, differentiation, and removal of specific cell types in heterogeneous cultures, utilizing systems like Optical Cell Processors (OCP) and laser-induced forward transfer (LIFT) for targeted cargo delivery and cell manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large-scale cell cultures are used for manipulation and study, then sufficient cell material is available for analysis, but precision and control over individual cells or specific cell types are lost
Solution Approach 1:
The patent applies local quality by enabling different genetic effects to be applied to different spatial locations within a cell culture. The system can target specific cells or cell types within a heterogeneous population using spatially-resolved genetic effectors, allowing precise manipulation of local cell regions while maintaining the overall culture context.
Solution Approach 2:
The patent segments the genetic manipulation process into temporally-controlled stages. Multiple genetic effectors are delivered in a sequential manner, with each effector performing a specific function at a defined time point. This temporal segmentation allows complex genetic operations to be broken down into manageable, precisely-controlled steps.
2Reliability
If step-wise genetic manipulation is used, then each genetic event can be controlled individually, but the overall process time and complexity increase
Solution Approach 1:
The patent employs preliminary action by pre-assembling multiple genetic effectors within a single vector construct before delivery. The vector is designed to contain multiple effector genes that will be expressed in a predetermined temporal sequence, allowing the system to prepare complex genetic manipulation protocols in advance and execute them more efficiently.
Solution Approach 2:
The patent merges multiple genetic effectors into a single deliverable vector system. Instead of delivering separate constructs for each genetic manipulation step, the system combines multiple effectors into one vector that can be introduced in a single transfection event, reducing the number of separate manipulation steps required.
3Adaptability or versatility
If mixed cell populations are cultured, then cellular interactions and heterogeneity can be studied, but selective manipulation or removal of specific cell types becomes difficult
Solution Approach 1:
The patent applies local quality by enabling spatially-resolved genetic manipulation within heterogeneous cell populations. The system can distinguish and target specific cell types or individual cells based on their spatial location or molecular markers, allowing selective manipulation while maintaining the diversity of the mixed population.

AI summary
The disclosure relates to growing cells, directing cells to grow into specified cell types, genetically and physically manipulating cells, and addressing one or more individual cells within a mixed cell population. Aspects of the disclosure relate to vectors useful to induce developmental changes in cells, in which those vectors have a temporal component. Vectors of the disclosure encode a controllable, temporal series of events. Once the vectors are delivered into target cells, a series of discrete and different genetic events may be induced. The disclosed methods generally provide for the temporal encoding of multiplex genetic effectors in vector format for cell state transitions.
