Disclosures herein are directed to chemically defined animal-derived component free supplements designed for individual cell types that supports the ex vivo growth of cells as well or better than serum, in chemically defined conditions.

A composition, for inducing chondrocyte differentiation or regenerating cartilage tissue or both, includes exosomes derived from stem cells differentiating into chondrocytes.

A method for producing CD4/CD8 double-positive T cells, comprising the steps of: (1) culturing pluripotent stem cells in a medium to induce hematopoietic progenitor cells; and (2) culturing the hematopoietic progenitor cells obtained in the step (1) in a medium containing a p38 inhibitor and/or SDF-1 to induce CD4/CD8 double-positive T cells.

The present invention relates to a fibrocartilage preparation method and fibrocartilage prepared by the method.

The present invention relates to a method for inducing the differentiation of corneal epithelial cells from pluripotent stem cells. More specifically, the present invention relates to a method for autonomously differentiating pluripotent stem cells, such as human iPS cells, into ectodermal cell lineage in a serum-free medium without using feeder cells and inducing the differentiation of the resultant ocular surface ectodermal lineage cells into corneal epithelial cells.

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.

Methods for derivation, culture, and maturation of small hepatic progenitor cells are described.

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.

The present disclosure provides for non-viral compositions and methods for delivering nucleic acids into eukaryotic cells (e.g., stem cells) with high efficiency and low genotoxicity.

The invention described herein is directed to compositions and methods for inducing red blood cell (RBC) differentiation. Additionally, provided herein are methods of treating a subject in need thereof by administering the induced RBC described herein.
