The invention relates to the use of germ cells for obtaining a micro hair follicle and to the use thereof for evaluating the effect of cosmetic, pharmaceutical or dermatological products and also for the prophylactic or therapeutic treatment of a state of reduced pilosity.

A method of generating a population of cells useful for treating a nerve disease or disorder in a subject, the method comprising up-regulating a level of at least one exogenous miRNA in mesenchymal stem cells (MSCs) and/or down-regulating a level of at least one miRNA using a polynucleotide agent that hybridizes to the miRNA, thereby generating the population of cells useful for treating the nerve disease or disorder. Isolated populations of cells with an astrocytic phenotype generated thereby and uses thereof are also provided.

A method for producing a regenerative organ germ for transplantation includes using regenerative organ germ for transplantation ensuring continuity with a recipient after transplantation and facilitating transplantation procedures. A method for producing a regenerative organ germ provided with a guide for transplantation includes preparing a regenerative organ germ by closely contacting a first cell mass, which substantially consists of mesenchymal cells, and a second cell mass, which substantially consists of epithelial cells, culturing these cell masses within a support, and inserting the guide into the regenerative organ germ.

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.
