Description

Technical Field

[0001] The invention relates in a first aspect to a processing chamber having a truncated first body section, in a second aspect to a kit including a processing chamber, in a third aspect to an apparatus suitable for receiving a processing chamber, in a fourth aspect to a method for culturing and processing cells in a processing chamber, and in a fifth aspect to the use of a processing chamber. Background Technology

[0002] Processing chambers are well-known in the field of cell culture and processing. In particular, document WO2019 / 234033 describes an apparatus and method for the automated production of genetically engineered cells from biological fluids.

[0003] This document describes a hollow processing chamber consisting of a hemispherical top portion, with the circular portion of the hemisphere facing upwards and having an opening at the very top. The edges of the hemisphere form a vertical angle with the hemisphere itself.

[0004] In any case, the spherical shape of the processing chamber cannot provide a large incubator volume for cell processing compared to the overall volume of the chamber. Furthermore, due to its spherical surface, the inner surface of the hemisphere is not very advantageous for incubating adherent cells. Summary of the Invention

[0005] Therefore, the problem to be solved by the present invention is to provide a processing chamber that provides a better total volume to incubator volume ratio and is more suitable for centrifugation and cell incubation, especially for incubating adherent cells.

[0006] The “processing chamber” is advantageously a centrifugal separation chamber.

[0007] The “processing room” is advantageously a bioreactor.

[0008] The term "chamber" advantageously refers to a hollow container or tank that can be filled with liquid.

[0009] The orientation of "vertical" is advantageously defined by the direction of local gravity.

[0010] The orientation "horizontal" advantageously refers to the direction perpendicular to the vertical direction.

[0011] This problem is solved by the processing chamber according to the first aspect of the invention.

[0012] The processing chamber is concentrically formed around a central axis and includes a first main section, a second main section, and a third main section, wherein, along the central axis, the first main section is followed by the second main section, and the second main section is followed by the third main section. Specifically, it should be clarified that the central axis is the central axis of the processing chamber itself.

[0013] The first main body section has a truncated conical shape with a first base side and a second base side. Advantageously, according to the definition of a truncated conical shape, the first base side and the second base side of the first main body section can be arranged parallel to each other, especially substantially parallel. This should also include the first base side and the second base side of the first main body section that are slightly misaligned and not perfectly parallel due to manufacturing problems or similar issues.

[0014] The diameter of the first base side of the first main body section is smaller than the diameter of the second base side of the first main body section, and the first base side forms the first end of the processing chamber in the axial direction of the central axis.

[0015] The second base of the first main body section extends into the second main body section. The second main body section extends along a central axis, wherein the first end of the second main body section points away from the first main body section, and the second end of the second main body section is adjacent to the first main body section. Advantageously, the diameter of the second main body section at the first end is smaller than the diameter of the second main body section at the second end.

[0016] Advantageously, an angle or edge is formed between the first body section and the second body section. This angle or edge is formed between the lateral inner surface of the first body section (the inner surface between the first base side and the second base side of the first body section, particularly the inner shell surface between the first base side and the second base side of the first body section) and the lateral inner surface of the second body section (the surface between the first end and the second end of the second body section).

[0017] The first end of the second main section leads into the conical third main section.

[0018] The third main section extends along the central axis in a direction pointing away from the second main section, wherein the first end of the third main section points away from the second main section. The first end of the third main section tapers to the second end of the processing chamber. Advantageously, the diameter of the second end of the processing chamber is smaller than the diameter at the first end of the second main section.

[0019] Advantageously, tapering into the second end of the processing chamber means that the third body section tapers until it ends at the tip or until an opening is left at the second end of the processing chamber.

[0020] Advantageously, the third main body section has a conical shape with an opening at the tip, and in particular, it has a truncated or frustum-like shape.

[0021] Advantageously, the processing chamber, comprising a first main body segment, a second main body segment, and a third main body segment, has a favorable shape for incubating cells. In particular, since the volume of the substantially truncated first main body segment is large compared to the total volume of the processing chamber, a larger volume of liquid can be centrifuged and incubated compared to processing chambers described in the prior art.

[0022] In another advantageous embodiment of the invention, the slope of the second body section about the central axis is greater than the slope of the third body section about the central axis.

[0023] Advantageously, the term "tilt height" here refers to the height of an object (e.g., a truncated body), which is the distance measured along the lateral plane from the first base to the vertex or the second base and along the center of the lateral plane.

[0024] In another advantageous embodiment of the invention, the second base side of the first body section extends into the truncated second body section.

[0025] Advantageously, the diameter of the first base side of the second main body section closer to the first main body section is greater than the diameter of the second base side of the second main body section away from the first main body section.

[0026] In another advantageous embodiment of the invention, the height h of the truncated second body segment f for h f ≤10mm, specifically h f ≤5mm.

[0027] Further advantageously, the second main body section is designed such that its surface line follows an elliptical, substantially elliptical, or circular contour into the surface line of the third main body section. Specifically, the surface line of the second main body section refers to the shortest line traveling along an inclined height between the second end of the second main body section and the first end of the second main body section. More specifically, the surface line of the third main body section refers to the shortest line between the second end of the third main body section and the first end of the third main body section in the direction of the central axis.

[0028] In another advantageous embodiment of the invention, the minimum angle α between the tilt height of the second main body section and the second base side is α≤20°, particularly α≤10°, particularly α≤5°.

[0029] In another advantageous embodiment of the invention, the processing chamber includes a first opening for flow exchange at a first end and / or a second opening for flow exchange at a second end.

[0030] In another advantageous embodiment of the invention, at least the inner shell surface or lateral inner shell surface of the first body section is coated with a bioactive coating. This means that at least the inner wall of the first body section is coated, particularly to better facilitate cell adhesion.

[0031] A second aspect of the invention relates to a kit comprising a processing chamber according to a first aspect of the invention. The processing chamber in the kit is connected to a first flow stator and / or a second flow stator. Furthermore, the kit includes a tubing assembly connectable to the first flow stator and / or the second flow stator, and adapted, for example, in a device, in the intended use of the kit, to be connected to at least one peristaltic pump head and at least one pinch valve. Additionally, the kit includes at least one reagent or product bag or bottle adapted to be connected to the tubing assembly.

[0032] A third aspect of the invention relates to an apparatus adapted to receive or include a processing chamber or a kit having a processing chamber. The apparatus is adapted to prepare gene-transformed cells from a biological fluid. The apparatus may include an operating unit adapted to receive the processing chamber according to the first aspect. Further advantageously, the apparatus may be adapted to orient the processing chamber about a rotational axis of the operating unit, particularly to orient the central axis of the processing chamber in a horizontal or vertical direction relative to the ground.

[0033] A fourth aspect of the present invention relates to a method for culturing and processing cells in a processing chamber according to a first aspect of the present invention. The method includes the following steps: Bring the processing chamber in so that the central axis is vertically aligned to allow the cells to be centrifuged, and / or Bring the processing chamber in so that the central axis is horizontally aligned with the position for incubating cells (especially suspended cells), and / or The operating unit is brought into position such that the surface line of the first main body segment is horizontally aligned for incubating cells (particularly adherent cells). Specifically, the surface line of the first main body segment refers to the shortest line traveling along the slope between the first and second basal sides of the first main body segment. More specifically, horizontal alignment of the surface line of the first main body segment means aligning the surface line along a horizontal plane.

[0034] Advantageously, the method is used to prepare gene-transformed cells from biological fluids using a processing chamber according to a first aspect of the invention and an apparatus according to a third aspect of the invention.

[0035] Further advantageously, the method therefore includes the step of rotating the operating unit of the device to a position where the central axis of the processing chamber is in a vertical position. Additionally, the method includes one of the following steps: rotating the operating unit to a position where the central axis of the processing chamber is in a horizontal position, or rotating the operating unit to a position such that the surface line of the first body section is horizontally aligned for incubating cells.

[0036] Bringing the processing chamber to a horizontal position means arranging the central axis horizontally, which can effectively incubate suspended cells.

[0037] Positioning the central axis of the processing chamber at a slight inclination relative to the horizontal plane means that the surface line of the first main section is horizontally aligned, which allows for effective incubation of adherent cells. In this position, cells can effectively adhere to the lateral inner surface of the first main section, particularly to the lateral inner surface of the first main section which is substantially horizontally aligned in this position of the processing chamber.

[0038] Advantageously, particularly regarding the handling of adherent cells, this method allows switching between three positions: a vertical central axis, a horizontal central axis, and a tilted central axis that aligns the surface line of the first main body segment horizontally. This is one of the advantages of the method, which allows for efficient centrifugation and incubation of biological cells while, for example, exchanging fluids.

[0039] Advantageously, the step of bringing the processing chamber to a vertical position with the central axis vertically aligned is a method step suitable for subjecting the liquid (cell suspension) in the processing chamber to centrifugation. Advantageously, the cell suspension can be centrifuged such that cell clusters form on the lateral inner surface near the first main section, and on the lateral inner surface between the first and second main sections, particularly at or near the edges, particularly formed between the surfaces and the angle formed between the first and second main sections. Further advantageously, when centrifugation is slowed or stopped, the supernatant or any other fluid can be collected at the bottom of the processing chamber. The supernatant or any other fluid can be removed from the processing chamber through a second opening in the processing chamber.

[0040] Further advantageously, after the centrifugation step, the processing chamber is brought to a position where the central axis is horizontally aligned. A liquid or solution can then be added to the processing chamber. The cell clumps can now be suspended in the solution by stirring. The suspended cells can then be further incubated to promote cell division. The advantage of the processing chamber now lies in the increased volume and increased lateral internal surface area resulting from its innovative shape.

[0041] In another advantageous embodiment of the invention, the method further includes the step of exchanging the liquid or solution in the processing chamber via a first opening and / or a second opening. Advantageously, the liquid or solution in the processing chamber is exchangeable only when the processing chamber is in a static position.

[0042] In another advantageous embodiment of the method, particularly for the centrifugation and incubation of suspended cells, the method may further include the following steps: Especially when the processing chamber is in a position where the central axis is vertically aligned, add (cell) suspension to the processing chamber, and / or The (cell) suspension is centrifuged by rotating the processing chamber around its central axis, particularly wherein cell clusters are formed on the lateral inner surface near the first main body segment, between the first and second main body segments, at the edges between the first and second main body segments, and / or When centrifugation slows down or stops, collect the supernatant at the bottom of the processing chamber (in the third main section), and / or Advantageously, after the centrifugation step, the processing chamber is brought to a horizontal position (with the central axis in a horizontal position) to allow any liquid or solution to be added to the processing chamber, and / or In particular, cell clusters are suspended by stirring, and / or While the processing chamber is in a horizontal position, the suspended cells are further incubated to promote cell division.

[0043] In another advantageous embodiment of the method, particularly for the centrifugation and incubation of adherent cells, the method may further include the following steps: The processing chamber is brought into a position where the surface line of the first main section is horizontally aligned, and a suspension of adherent cells, particularly from the growth medium, is added to the processing chamber, and / or Especially during the rotation of the processing chamber, cells form an adherent layer on the lateral inner surface of the first main segment, and / or When the treatment chamber is positioned horizontally to the surface line of the first main section (the surface line of the first main section is horizontally aligned), add the growth medium to the treatment chamber, and / or When the processing chamber is in a vertical position (central axis in a vertical position), the growth medium is collected and removed, while the adherent cell layer remains on the lateral inner surface of the first main section, and / or Especially after cell growth, particularly when the treatment chamber is positioned at the level of the surface line of the first body segment, a trypsinizing agent is added to the treatment chamber, wherein the trypsinizing agent can release cells attached to the laterally inner surface of the first body segment, and / or The trypsin solution and trypsin reagent were removed separately from the processing chamber along with the suspended cells for further use.

[0044] Various embodiments of the method according to the fourth aspect are advantageously used for closed and automated cell processing. In particular, automated cell processing is provided if the method is operated on an apparatus according to the third aspect of the invention. The special shape of the processing chamber allows different method steps to be run in all steps using the same processing chamber in a sterile and closed environment. Therefore, the result is more efficient and safer cell culture and processing, as all necessary steps of centrifugation and growth can be performed in the same processing chamber.

[0045] The fifth aspect of the invention relates to the use of a processing chamber according to the first aspect of the invention for preparing gene-transformed cells from a biological fluid by a method according to the fourth aspect of the invention.

[0086] In an advantageous embodiment, the step of bringing the processing chamber 100 into a position where the surface line 16 of the first main body section 1 is horizontally aligned on the horizontal plane 110 (horizontal position of the surface line of the first main body section) can be performed alternately with the step of bringing the processing chamber 100 into a position where the central axis 101 is vertically aligned (vertical position).

[0087] like Figure 8 As shown in step ii, a suspension 102 of adherent cells in the growth medium is added to the treatment chamber 100.

[0088] like Figure 8 As shown in step iii, when the processing chamber 100 rotates, the cells will form an adherent layer 105 on the lateral inner surface of the first body segment 1. Since the processing chamber 100 is aligned such that the surface line 16 of the first body segment 1 is horizontally aligned along the horizontal plane 110, the cells can advantageously adhere to the lateral inner surface 15 of the first body segment 1.

[0089] Furthermore, particularly when the processing chamber is positioned at the horizontal level of the surface line of the first main section ( Figure 8 (Step iii) can be used to add growth medium 106 to treatment chamber 100.

[0090] In the vertical position of the processing chamber 100 (meaning the processing chamber 100 is brought into a position where the central axis 101 is vertically aligned), the growth medium 106 can be collected. Figure 8 Step v) removes the growth medium again through the first opening 13 at the first end 10 of the treatment chamber 100 or through the second opening 31 at the second end 30 of the treatment chamber 100. Figure 8 Step v), while the adherent cell layer 105 remains on the lateral inner surface 15 of the first main body section 1.

[0091] Advantageously, after growth, trypsinizing agent 107 can be added to the treatment chamber through a first opening 13 at the first end of the treatment chamber and / or through a second opening 31 at the second end of the treatment chamber. Figure 8 vi). In order to add trypsinizing agent 107, in particular, the treatment chamber 100 can be positioned at the level of the surface line of the first main body section (vi). Figure 8 Steps vi and vii). The trypsinizing agent 107 can release cells attached to the lateral inner surface 15 of the first host segment 1 by cleaving peptide bonds. Thus, the adherent cells or adherent cell layer 105 are suspended in trypsin solution or in trypsin agent, respectively. Figure 8 (step vii), and can be removed from the processing chamber 100 for further use, for example by bringing the processing chamber into an upright position and releasing cells through a first opening 13 at the first end 10 of the processing chamber 100 or through a second opening 31 at the second end 30 of the processing chamber 100. Figure 6 Step viii), or by following Figure 6 The steps shown in steps i to v wash the cells out of the processing chamber using trypsin.
