Abstract
A method of generating neural stem cells or motor neurons is disclosed, the method comprising up-regulating a level of at least one exogenous miRNA and/or down-regulating at least one miRNA using an agent which hybridizes to the miRNA in mesenchymal stem cells (MSCs) or down-regulating Related to testis-specific, vespid and pathogenesis protein 1 (RTVP-1).
Claims4
A method of promoting mesenchymal stem cell (MSC) differentiation toward a neuronal stem cell, the method comprising:
- (i) culturing a MSC in a medium supporting neuronal stem cell growth and differentiation,
- (ii) introducing into said MSC at least one exogenous microRNA (miR) selected from the group consisting of miR-20B, miR-378 and miR-891,
- (iii) introducing into said MSC a miR-138 antagomir, and
- (iv) confirming increased expression at least one neuronal marker selected from the group consisting of nesting and Sox2 by detecting expression of said marker on said MSC, thereby promoting differentiation of the MSC into the neuronal stem cell.
