A composition for inducing differentiation into adipocytes or regenerating adipose tissues comprises, as an ingredient, exosomes derived from stem cells differentiating into adipocytes, or exosomes derived from proliferating stem cells.

Human progenitor T cells that are able to successfully engraft a murine thymus and differentiate into mature human T and NK cells are described. The human progenitor T cells have the phenotype CD34+CD7+CD 1aCD5 or CD34+CD7+CD1aCD5+ and are derived from human hematopoietic stem cells, embryonic stem cells and induced pluripotent stem cells by coculture with cells expressing a Notch receptor ligand (OP9-DL1 or OP9-DL4). Such cells are useful in a variety of applications including immune reconstitution, the treatment of immunodeficiencies and as carriers for genes used in gene therapy.

A method for preparing a bioactive composition containing conditioned cell culture medium is disclosed. The method comprises culturing cells of two or more eukaryotic cell line to form conditioned culture media, separating the cultured cells from the conditioned culture media, and combining conditioned culture media to form a bioactive composition. Novel bioactive compositions, formulations and their use in treating of a variety of diseases and health conditions are also disclosed.

Described are Neo-Islets comprising: a) dedifferentiated islet cells and mesenchymal and/or adipose stem cells; or b) redifferentiated islet cells and mesenchymal and/or adipose stem cells where the cells have been treated so as to facilitate redifferentiation. Further described herein are methods of generating Neo-Islets, the methods comprising: culturing a) dedifferentiated islet cells and mesenchymal and/or adipose stem cells; or b) redifferentiated islet cells and mesenchymal and/or adipose stem cells; on a surface that promotes the formation of cell clusters. Also described are methods of treating a subject, the methods comprising: providing to the subject Neo-Islets described herein. Additionally described are methods of treating a subject suffering from Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and other types of insulin-dependent diabetes mellitus, or impaired glucose tolerance by providing to the subject Neo-Islet as described herein. Additionally described are methods of treatment in which intraperitoneal administration of islet-sized Neo-Islets composed of high numbers of mesenchymal stem cells and cultured islet cells, durably and reversibly treats, without hypoglycemia, both streptozotocin-induced and spontaneous Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, and other types of insulin-dependent diabetes mellitus, or impaired glucose tolerance.

A method for co-cultivation and directed differentiation induction of muscle satellite cells and adipose-derived stem cells is provided. The method includes the steps of co-cultivation and co-differentiation. The method for co-cultivation and directed differentiation induction of muscle satellite cells and adipose-derived stem cells provided by the present disclosure can allow the effective co-cultivation and co-directed differentiation induction of muscle satellite cells and adipose-derived stem cells from Larimichthys crocea, thereby providing a feasible solution for the large-scale production of high-quality cultivated meat.

The invention relates to a population of cells, wherein said population of cells comprises at least 50% macrophage or monocyte cells, characterised in that at least 50% of said macrophage or monocyte cells express each of the markers: MRC1; TIE2; and CD163. The invention also relates to uses of those cells, methods of making them and methods of treating a subject by administering them.

Methods of inducing a polarization of macrophages. The method includes obtaining a blood fraction, fractionating the blood fraction to produce a blood fraction, and contacting the blood fraction with a source of macrophages. A blood fraction including platelet-poor plasma polarizes the source of macrophages into M1 macrophages. A blood faction including a protein solution polarizes the source of macrophages into M2 macrophages.

The present invention is directed to compositions for treating oxidative-stress related-damage of retinal pigment epithelium (RPE) cells by contacting orbital fat-derived mesenchymal cell with the damaged RPE cells.
