A method of manufacturing a multilayered cell sheet of neural crest stem cells (NCSCs), includes: (1) isolating and culturing NCSCs from peripheral nerves; (2) embedding the cultured NCSCs in a hydrogel; (3) culturing the hydrogel comprising the NCSCs embedded therein under stressed culture conditions in which a physical support is applied; and (4) culturing the resulting hydrogel of step (3) under non-stressed culture conditions in which a physical support is removed.

The invention relates to a new type of mesenchymal stem cells (MSC) which co-express at least one mesenchymal marker, preferably at least CD105 and CD34. Also provided are bone-forming cells having an analogous phenotype. The invention also provides the cells and cell populations, as well as further products comprising such and uses thereof in bone therapy.

Disclosed are methods for making a vascularized hollow organ derived from human intestinal organoid (HIOs). The HIOs may be obtained from human embryonic stem cells (ESC's) and/or induced pluripotent stem cells (iPSCs), such that the HIO forms mature intestinal tissue. Also disclosed are methods for making a human intestinal tissue containing a functional enteric nervous system (ENS).

Disclosed herein are cell cultures and enriched cell populations of endocrine precursor cells, immature pancreatic hormone-expressing cells and mature pancreatic hormone-expressing cells. Also disclosed herein are methods of producing such cell cultures and cell populations.

Described herein are chemically defined, adherent culture protocols for generating functional motor neurons characteristic of diverse hindbrain and spinal cord regions, with high efficiency.

The invention is directed to methods for culturing cells so that the cells are induced to differentiate into cells that express a hepatic stellate phenotype and cells that express a hepatic sinusoidal endothelial phenotype. The invention is also directed to cells produced by the methods of the invention. The cells are useful, among other things, for treatment of liver deficiency, liver metabolism studies, and liver toxicity studies.

The invention relates to improved culture methods for expanding epithelial stem cells and obtaining organoids, to culture media involved in said methods, and to uses of said organoids.

Disclosed are methods of inducing formation of a gastric cells and/or a gastric tissue, such as in the form of a gastric organoid. The formation of gastric cells and/or tissue may be carried out by the activating and/or inhibiting of one or more signaling pathways within a precursor cell. Also disclosed are methods for using the disclosed gastric cells, gastric tissues, and/or gastric organoids derived from precursor cells.

Disclosed herein are cell cultures comprising dorsal and/or ventral PDX1-positive foregut endoderm cells and methods of producing the same. Also disclosed herein are cell populations comprising substantially purified dorsal and/or ventral PDX1-positive foregut endoderm cells as well as methods for enriching, isolating and purifying dorsal and/or ventral PDX1-positive foregut endoderm cells from other cell types. Methods of identifying differentiation factors capable of promoting the differentiation of dorsal and/or ventral PDX1-positive foregut endoderm cells, are also disclosed.

An object is to prepare an intestinal organoid having a characteristic close to the small intestine of a living body, from a pluripotent stem cell. An intestinal organoid is prepared from a pluripotent stem cell, by the following steps of: (1) differentiating the pluripotent stem cell into an endoderm-like cell; (2) differentiating the endoderm-like cell obtained in step (1) into an intestinal stem cell-like cell; (3) culturing the intestinal stem cell-like cell obtained in step (2) in the presence of an epidermal growth factor, a fibroblast growth factor, a TGF β receptor inhibitor, a GSK-3 β inhibitor, and a ROCK inhibitor; (4) culturing the cell obtained in step (3) to form a spheroid; and (5) differentiating the spheroid formed in step (4) to form an intestinal organoid, wherein the differentiation includes culturing in the presence of an epidermal growth factor, a BMP inhibitor, and a Wnt signal activator. Also, a plane culture system is prepared by subjecting the cells constituting the intestinal organoid formed in step (5) to plane culture in the presence of an epidermal growth factor and a TGF β receptor inhibitor. A highly functional evaluation system having the villi structure is constructed by using air-liquid interface culture in the plane culture.
