Various embodiments of the invention provide methods of treating diabetes and other glucose regulation disorders. In one embodiment, the method comprises removing L-cells from a donor, obtaining stem cells from a patient, and culturing the L-cells in the presence of the stem cells under conditions such that the stem cells differentiate into stem cell-derived L-cells (SCDLC). An amount of the SCDLC is introduced into the patient sufficient to cause a lowering of the patient's blood glucose level after ingestion of food. In another embodiment, the method comprises removing K-cells from a donor, obtaining stem cells from a patient, and culturing the K-cells in the presence of the stem cells under conditions such that the stem cells differentiate into stem cell-derived K-cells (SCDKC). An amount of the SCDKC is introduced into the patient sufficient to cause a lowering of the patient's blood glucose level after ingestion of food.

The present invention relates to the use of polysulfated polysaccharides in combination with progenitor cells to improve the viability of the progenitor cells including improving the cryopreservation of the progenitor cells and provides novel compositions, methods and uses. The present invention also relates to the use of polysulfated polysaccharides to regulate the proliferation and differentiation of progenitor cells.

A mesenchymal stem/stromal (MSC) cell line, in particular a human mesenchymal stem cell (hMSC), capable of chondrogenic differentiation when cultured in a chondrogenic medium, comprising a first transgene comprising a first nucleic acid sequence encoding for a preferably mammalian immortalizing enzyme under control of a first promoter sequence operable in said mesenchymal cell and a second transgene comprising a second nucleic acid sequence encoding a preferably mammalian bone morphogenic protein under control of a second promoter sequence operable in said mesenchymal cell.

There is provided a method of selectively differentiating mesenchymal stem cells into a first predetermined cell lineage associated with the nuclear localization of Yes-associated protein (YAP) or into a second predetermined cell lineage associated with the cytoplasmic localization of YAP. The curvature of the nucleus is controlled to have a maximum nuclear curvature (Kmax) of at least 0.5 ?m.sup.?1 to select for the first predetermined cell lineage, or a Kmax that does not exceed 0.5 ?m.sup.?1 to select for the second predetermined cell lineage. The mesenchymal stem cells having a controlled nuclear curvature are incubated in a media with or without differentiation additives to obtain the first predetermined cell lineage or the second predetermined cell lineage.

The present invention provides new protease resistant polypeptides, as well as compositions and methods for treating, ameliorating or preventing conditions related to joint damage, including acute joint injury and arthritis.

The present invention relates to a medium composition containing an Ecklonia cava extract for dedifferentiating an induced pluripotent stem cell. Also, the present invention relates to a method for differentiating an induced pluripotent stem cell, produced by using the medium composition into a chondrocyte. When using the medium composition according to the present invention, induced pluripotent stem cells using mesenchymal stem cells can be produced efficiently, and the pluripotent stem cells which have been produced can be useful as a cell treatment agent by being capable of being differentiated into chondrocytes.

The invention relates to implantable collagen devices made by seeding at least one elongate collagen construct, e.g., comprising at least one elongate synthetic collagen fiber with a plurality of cells and applying a strain and/or stress to the at least one elongate collagen fiber to induce the cells to differentiate into target phenotypes, e.g., tendon or ligament phenotype cells (and/or fibroblasts), typically with an extracellular matrix of collagen to organize into a tissue on the at least one collagen fiber.

The present invention relates generally to methods and compositions useful for therapeutic vascular tissue engineering. In particular, the present invention provides methods for generating substantially pure populations of vasculogenic cells from human mesenchymal progenitors, and methods and compositions for clinical applications in the field of regenerative medicine.
