The present invention relates to: a composition for promoting the proliferation of pluripotent stem cells, containing, as an active ingredient, cP1P or a pharmaceutically acceptable salt thereof; and a composition added to a stem cell culture liquid. When culturing stem cells by using a composition for promoting the proliferation of stem cells and a composition added to a stem cell culture medium, according to the present invention, sternness can be strengthened, growth can be promoted, and apoptosis can be inhibited.

The present specification provides: a method of isolation of a pure culture of vascular endothelial cells, the method capable of isolating homogeneous endothelial cells adhered to a matrix for a specific time in a cell line of an endothelial cell lineage differentiated from human pluripotent stem cells; a medium for maintaining characteristics of vascular endothelial cells, comprising high-purity vascular endothelial cells isolated through the method, 4 ng/ml to 6 ng/ml of FGF2, 5 ng/ml to 10 ng/ml of EGF, 10 ng/ml to 30 ng/ml of VEGF-A, 20 ng/ml to 50 ng/ml of ascorbic acid, and DMEM/F-12 as active ingredients; and a culture method comprising same.

A system for an iPS cell bank includes a terminal and a server. The terminal receives and sends a production request including a desired collection date of a somatic cell and a customer ID to the server. The server stores a collectable date for collecting the somatic cell, a producible period for producing an iPS cell, and a location and a stockable period for stocking the iPS cell; and determines: a collection date based on the desired collection date and the collectable date; a production period based on the collection date and the producible period; an acceptance date of the somatic cell based on the collection date and the production period; a stock location and a stock period based on the production period, the stockable location, and the stockable period; and a shipment date of the iPS cell based on the production period, the stockable location, and the stockable period.

The present invention refers to a method for reducing expression of a target RNA in an isolated cell in preparation for cell therapy, comprising incubating the isolated cell comprising the target RNA with an antisense oligonucleotide without use of a transfection means, wherein the antisense oligonucleotide is administered to the isolated cell at least once in a time period of day 0 to day 21, the antisense oligonucleotide hybridizes with the target RNA and reduces the transcription of the target RNA, reduces the expression of the protein encoded by the target RNA or a combination thereof up to 8 weeks from day 0 of the incubation with the antisense oligonucleotide. The invention further relates to an isolated cell obtainable by the method of the present invention and a pharmaceutical composition comprising the isolated cell. The isolated cell and the pharmaceutical composition are used in a method of preventing and/or treating a disease.

Described herein a polycistronic expression cassettes and expression vectors that include a promoter operably linked to a nucleic acid segment that encodes a Sox2 and Klf4 polypeptide. The nucleic acid segment can also encode a c-Myc polypeptide. Expression of such polycistronic expression cassettes/vectors in host cells can reprogram the host cells to stem cells or other types of reprogrammed cells.

In order to cut a plurality of clumps having an approximately uniform shapes and approximately uniform dimensions out of a cell aggregate which has proliferated and appropriately eliminate contamination with fragments of different shapes or dimensions, when cutting the clumps of approximately uniform shape out of the cell aggregate which has proliferated, cutting lines along which the clumps of a specific shape are cut out are set such that the area of a peripheral part of the cell aggregate which is not cut by the cutting line exceeds the surface area of one of the clumps, and the cell aggregate is cut by irradiating with laser light in such a way as to trace the cutting lines.

Provided is a cell culture method comprising the step of culturing cells using a medium containing a laminin fragment having integrin binding activity, the method not comprising the step of coating a culture vessel with a laminin or a laminin fragment before seeding the cells in the culture vessel. The cell culture method of the present invention uses a smaller amount of a laminin fragment and still achieves a comparable culture efficiency as compared with the conventional cell culture method that uses a culture vessel precoated with a laminin or a laminin fragment.

This invention relates to compositions of matter, methods, modules and automated, end-to-end closed instruments for automated mammalian cell growth, reagent bundle creation and mammalian cell transfection followed by nucleic acid-guided nuclease editing in live mammalian cells. The disclosed compositions and method entail making “reagent bundles” comprising many (hundreds of thousands to millions) clonal copies of an editing cassette and delivering or co-localizing the reagent bundles with live mammalian cells such that the editing cassettes edit the cells and the edited cells continue to grow.

The present invention relates to a method of expanding pluripotent stem cells (PSC) in suspension culture in a bioreactor, the method comprising (i) adding an inhibitor of ROCK (ROCKi) to pluripotent stem cells being cultivated in suspension in the bioreactor; (ii) adding a cell dissociation agent, thereby dissociating aggregates of the pluripotent stem cells; (iii) diluting the cell dissociation agent added in step (ii) by adding an excess volume of culture medium sufficient to decrease the concentration of the cell dissociation agent to a concentration at which cell aggregates can form again; and (iv) culturing of the mixture obtained in step (iii) under suitable conditions that allow the expansion of the PSCs.

According to the present disclosure, provided is a method for manufacturing induced pluripotent stem cells including preparing cells and introducing RNA into the cells, wherein the RNA includes RNA encoding a reprogramming factor and wherein, in the RNA introduced into the cells, double-stranded RNA is substantially removed.
