Provided are a primary cell culture medium that contains a combination of an MST1/2 kinase inhibitor and a ROCK kinase inhibitor and is used for culturing primary esophageal squamous cell carcinoma epithelial cells, and a culture method using the primay cell culture medium. In the culture method, the primary cell culture medium is used to culture primay cells on a culture vessel coated with an extracellular matrix glue, so that the primary cells prolilferate rapidly. A cell model obtained by using the primary cell culture medium and the primary cell culture method of the present invention can be used for the efficacy evaluation and screening of drugs.

The present invention relates to a method for producing induced dopaminergic neuronal progenitors from adult cells using direct reprogramming, induced dopaminergic neuronal progenitors produced via the method and a use for same, wherein, as a result of having been directly reprogrammed from adult cells, the induced dopaminergic neuronal progenitors produced by means of the present invention can be transplanted inside a living body without the risk of oncogenicity, and have excellent proliferative capacity and dopaminergic neuronal differentiation potency, thus can be usefully utilized as a cell therapy product for Parkinson's disease.

Provided is a method for freezing a cell aggregate including neural cells. provided is a method for freezing a cell aggregate including neural cells and having a three-dimensional structure, which comprises following steps (1) and (2): (1) contacting a cell aggregate including neural cells and having a three-dimensional structure with a preservation solution at 0° C. to 30° C. prior to freezing to prepare a preservation solution-soaked cell aggregate; and (2) cooling the preservation solution-soaked cell aggregate obtained in step (1) from a temperature at least about 5° C. higher than the freezing point of the preservation solution to a temperature about 5° C. lower than the freezing point at an average cooling speed of 2 to 7° C./min to freeze the cell aggregate.

Provided are methods for producing population of cells enriched for cells exhibiting sinoatrial node like characteristics. The cells can be produced from human pluripotent cells. Also provided are methods for using the SAN-like cells for identifying agents that can mitigate drug-induced cardiac toxicity. Also provided is a method for mitigating drug induced cardiotoxicity comprising administering to a subject an effective amount of physcion or a derivative thereof.

A production method for an organoid, the production method including a step of culturing adult stem cells or a cell tissue piece including adult stem cells in a medium containing a chimeric Fibroblast Growth Factor (FGF) that includes a partial region of FGF1 and a partial region of FGF2; an organoid produced by the production method; a medium including a chimeric FGF and having a content of chimeric FGF of 50 ng/mL or less; and an evaluation method for a test substance are provided, and according to the chimeric FGF, a content of growth factors included in a medium can be reduced.

A medium composition, containing a basic fibroblast growth factor (bFGF) at not less than 150 ng/mL is useful for culturing cells.

The present disclosure relates to genetically modified T cells comprising a transgene encoding an engineered antigen specific receptor, wherein expression of an endogenous gene selected from MNK1, MNK2, or both are inhibited in the genetically modified T cell in order to enhance central memory T cell subsets in cellular immunotherapy compositions.

Provided are small molecule inhibitors for amplifying hematopoietic stem cells (HSCs) and a combination thereof. The small molecule inhibitors and the combination thereof can maintain the sternness of hematopoietic stem cells while promoting the in vitro amplification of hematopoietic stem cells (HSCs).

Methods for generating human committed midbrain neural stem cells (NSCs) and midbrain neural progenitor cells (midbrain NPCs) from human pluripotent stem cells are provided using chemically-defined culture media that allow for generation of the midbrain NPCs in as little as six days. The midbrain NPCs can be further differentiated to mature dopaminergic neurons. Culture media, isolated cell populations and kits are also provided.

A method of obtaining a pluripotent-like multipotent cell, including providing a cell of a first type which is not a pluripotent-like multipotent cell; contacting the cell of a first type with an agent capable of remodeling the chromatin and/or DNA of the cell; transiently increasing expression of at least one pluripotent gene regulator in the cell of a first type, to a level at which the at least one pluripotent gene regulator is capable of driving transformation of the cell of a first type into the pluripotent-like multipotent cell; and placing or maintaining the cell in a differentiation medium and maintaining intracellular levels of the at least one pluripotent gene regulator for a sufficient period of time to allow a stable pluripotent-like multipotent cell to be obtained; wherein the pluripotent-like multipotent cell so obtained does not exhibit teratoma formation in vivo.
