The disclosure relates to stem cells and their therapeutic use in the treatment and/or prevention of pancreatic diseases or disorders. Provided herein are compositions comprising c-kit positive pancreatic stem cells and methods of preparing and using c-kit positive pancreatic stem cells for the treatment and/or prevention of pancreatic diseases or disorders.

Embodiments of the disclosure encompass methods and compositions related to the ability of RNA to enhance therapeutic activity of fibroblasts. In some embodiments, administration of double stranded RNA is performed through providing polyinosinicpolycytidylic acid (poly (I:C)) or a derivative thereof at a concentration sufficient to induce therapeutic properties and/or to augment therapeutic properties onto said fibroblasts. In one embodiment, enhanced therapeutic activity comprises augmentation of fibroblast migratory activity; efficacy for angiogenesis; efficacy for immune modulation; differentiation ability; production of one or more trophic factors; and/or the ability to resist apoptosis.

The present disclosure relates to a composition for inhibiting the extension of a population doubling time of stem cells, comprising a c-Met agonist antibody as an active ingredient, and more particularly, to a medium additive for inhibiting the extension of a population doubling time of stem cells, comprising a c-Met agonist antibody as an active ingredient, a medium composition for culturing stem cells, comprising the medium additive, and a method for inhibiting the extension of a population doubling time.

This application relates to non-human primate (NHP) induced pluripotent stem cell (IPSC)-derived hepatocytes, for example, Cynomolgus monkey (Macaca fascicularis) induced pluripotent stem cell-derived hepatocytes, and methods of producing the same. Moreover, this application relates to methods of using NHP IPSC-derived hepatocytes for drug screening, drug safety assessment and in models of infection.

The present disclosure provides methods for generating an in vitro model of cholestatic liver disease and uses of the same. In some embodiments, the methods involve an in vitro culture system for producing hepatocyte-like cells from pluripotent stem cells.

Provided herein are, inter alia, extracellular products (e.g., vesicles such as microvesicles, e.g., exosomes) produced by renal cells (such as bioactive renal cells, e.g., selected renal cells). Methods of altering components (such as miRNAs or proteins) of vesicles produced by cells, as well as methods of producing vesicles comprising various compounds are also included. Also provided are diagnostic and treatment methods

Cells derived from postpartum tissue and methods for their isolation and induction to differentiate to cells of a chondrogenic or osteogenic phenotype are provided by the invention. The invention further provides cultures and compositions of the postpartum-derived cells and products related thereto. The postpartum-derived cells of the invention and products related thereto have a plethora of uses, including but not limited to research, diagnostic, and therapeutic applications, for example, in the treatment of bone and cartilage conditions.

The present invention relates to a cell culture medium for preparing liver, gastric, pancreatic, colon or intestinal adult stem cell isolated from adult tissue, as well as for maintaining such stem cell in the undifferentiated state. The cell culture medium comprises a base medium; an ABL and SRC dual kinase inhibitor/an ABL kinase inhibitor and a SRC kinase inhibitor; a mitogenic factor; a WNT signalling pathway activator; a stimulator for NAD+ and NADP+ generation; and a cAMP/P KA pathway activator. In a particular embodiment, the ABL and SRC dual kinase inhibitor is Dasatinib; the mitogenic factor is EGF; the WNT signalling pathway activator is R-Spondin 1; the stimulator for NAD+ and NADP+ generation is nicotinamide; and the cAMP/PKA pathway activator is cholera endotoxin.

The present invention relates to a cell differentiation medium composition, a high secretion insulin-producing cells and a preparation method thereof. The high secretion insulin-producing cells obtained by using the cell differentiation medium composition to induce stem cell differentiated under specific conditions can secrete a large amount of insulin in a short time, and when the high-secreting insulin-producing cells are transplanted into the human body, they are not easy to be swallowed by macrophages, which can improve the survival rate of the insulin-producing cells and prolong the time of insulin secretion thereby.

A method for generating a three-dimensional neuromuscular organoid in vitro is disclosed. This method comprises the following steps: a) providing a first cell culture comprising neuromesodermal progenitor cells and cultivating the neuromesodermal progenitor cells in a first differentiation medium chosen from the group consisting of i) a non-supplemented serum-free cell culture medium and ii) a serum-free cell culture medium supplemented with at least one of a ROCK inhibitor, an activator of a growth factor signaling pathway, and an activator of an insulin signaling pathway; b) replacing the first differentiation medium by a second differentiation medium within 1 to 3 days after cultivation start, wherein the second differentiation medium is chosen from the group consisting of i) a non-supplemented serum-free cell culture medium and ii) a serum-free cell culture medium supplemented with at least one of an activator of a growth factor signaling pathway, and an activator of an insulin signaling pathway; c) replacing the second differentiation medium by a non-supplemented serum-free cell culture medium within 1 to 3 days after replacing the first differentiation medium by the second differentiation medium; and d) obtaining a three-dimensional neuromuscular organoid from the non-supplemented serum-free cell culture medium.
