    Abstract: The present invention relates to a method for generating melanocytes from stem cells comprising the steps of: (i) removing the bulb of an epilated human hair; (ii) incubating the remaining part of the epilated hair with a collagen degrading agent to separate stem cells from the outer root sheath; (iii) cultivating the separated stem cells from step (ii) in a medium that induces differentiation and stimulates growth of stem cells, melanocyte precursors and melanocytes, wherein the medium comprises one or more growth factors for differentiation into melanotic melanocytes. Furthermore, a method for producing an autograft, a homograft or an allograft comprising melanocytes is disclosed herein as well as autografts, a homografts and allografts or melanocytes for the treatment of diseases related to depigmentation of the skin or for the treatment of scars.

    Abstract: The invention provides a method of producing oligodendrocytes by in vitro differentiation of human multi-potent progenitor cells (MLPCs). The method comprises culturing culturing isolated MLPCs on a first surface in a serum-free defined culture medium; replacing the culture medium with serum-free culture medium supplemented with bFGF, EGF and PDGF-AA for approximately 24 hours; changing the cultured MLPCs into the supplemented serum-free culture medium further supplemented with differentiation factors norepinephrine, forskolin. and K252a; establishing a 3D environment by covering the culture with a second surface opposite and spaced apart from the first surface, so as to contain the MLPCs therebetween; and continuing to culture until a majority of the MLPCs have differentiated into oligodendrocytes. Additionally included is a method of treatment for a subject afflicted by a disease characterized by central or peripheral nervous system demyelination, the method comprising transplanting into the subject oligodendrocytes produced according to the method disclosed.
