DEVICE FOR SEEDING CELLS
A device for seeding cells includes a container with a wall, a bottom and a lid. The wall extends between the bottom and the lid. The container can be equipped to be loaded with cells, in particular with cells form a cell suspension. The container defines a rotation axis. The device is further equipped to rotate the container around the rotation axis. The container includes a structured surface that can be arranged at the inner surface of the container. The structured surface has structures equipped to receive the cells. The rotation exerts a (g-)force in direction of the structured surface, such that the g-force acts perpendicular to the structured surface. The exerted force in the direction of the structured surface resembles a g-force required for sedimentation of the cells into the structures.
METHOD AND APPARATUS FOR ISOLATING DESIRED CELLS FROM SUSPENSIONS WITH NON-MAGNETIC BIOLOGICAL MATERIALS
The present invention concern a method and a device for the isolation of non-magnetic cells from a heterogeneous sample solution containing biological material including desired and undesired cells. The method comprises the steps of: —adding magnetic or magnetizable particles to the sample, wherein said particles have sizes in a range from 100 nm to 4 μm and exhibit surface components which support specific association with target cells, wherein said target cells comprise are either said desired or said undesired cells; —decreasing said external magnetic field gradient; —incubating said sample solution with said magnetic particles to obtain a magnetized cell fraction; —washing said magnetized cell fraction using a washing solution to reduce non-specific binding; —increasing said external magnetic field gradient; —separating said magnetized cell fractionation of target cells from said sample; wherein said sample solution is subjected to an external magnetic field gradient throughout said adding, incubating, washing and separating steps, and wherein said sample solution is rotated at least during said adding, incubating and washing steps.
CELL CULTURE BOTTLE
The invention relates to a cell culture bottle for adherent cells (e.g. human mesenchymal stem cells), comprising: a vessel; an internal cylinder, which has an internal Archimedes screw; an internal central tube, through which liquid can flow; and at least one wall arranged around the central tube. This arrangement provides an enlarged inner surface for the growth of the cells and for the reliable mixing of the fluid. The cell culture bottle is formed as a single piece and can be simply and economically produced as a disposable device by means of additive manufacturing.
Systems and methods for point/center-of-care immunotherapy
A cell modification device, comprising a centrifugation chamber with at least one cell modifying surface with a normal vector having an angle of 135-45° to the rotational axis of the centrifugation chamber, wherein the centrifugation chamber comprises at least one input/output port and the cells to be modified are immobilized at the cell modifying surfaces by the rotation of the centrifugation chamber at 2 to 2000 g. In an embodiment, the device is used as a point-of-care and/or portable device. Further, the present disclosure describes software that, when executed by a processor, causes the device to perform the disclosed functions.
MEDICAL DEVICE HAVING SPACE FOR ASSISTING IN EMBEDDING OF BIO SAMPLE IN EMBEDDING MATERIAL
It was difficult to create a thin bio sample embedded in an embedding material without using an expensive microtome. The present invention provides a medical device having a space for assisting in the embedding of a bio sample in an embedding material, the medical device being provided with a cover part and a base part having a recessed section in which the space is created by covering the cover part, wherein the base part is provided with a flow passage having an inlet section that is in fluid communication with the space, and the flow passage is configured such that when a force is applied to the medical device so that the volume of the space decreases, the embedding material flows out while preventing a positional misalignment of the bio sample inside the embedding material.

COMPOSITIONS, METHODS, MODULES AND INSTRUMENTS FOR AUTOMATED NUCLEIC ACID-GUIDED NUCLEASE EDITING IN MAMMALIAN CELLS USING MICROCARRIERS
Compositions of matter, methods, modules, and automated instruments may relate to synthesizing a library including an editing cassette including a different gRNA and donor DNA pair, amplifying the editing cassette in a partition separate from other editing cassettes in the library, adding nuclease to the partition, and adding lipofectamine to the editing cassette and nuclease to form a lipofectamine/nucleic acid/nuclease complex. A microcarrier coated in extracellular matrix or a cell adhesion molecule coating may be added to the lipofectamine/nucleic acid/nuclease complex. Cell growth material, the microcarrier, and mammalian cells may be transferred to a growth module in an automated closed cell editing instrument via a liquid handling system. The mammalian cells may be allowed to seed on the microcarrier. Conditions may be provided for the mammalian cells to take-up and be edited by a payload associated with the lipofectamine/nucleic acid/nuclease complex.
