neural stem cells (nscs) as a heterogeneous multipotent and self- renewal population are found in different areas in the developing mammalian nervous system, as well as the sub-ventricular zone (svz) and the hippocampus of the adult brain. nscs can give rise to neurons, astrocytes and oligodendrocytes. the aim of this study was to differentiate neural stem cells into noradrenergic–like cells in...

background: mesenchymal stem cells (mscs) are multipotent cells that can be collected from different sources. under specific conditions, mscs can be differentiated to tissue specific cells in vitro. human umbilical cord mesenchymal stem cells (hucmscs) can easily be harvested and cultured in in vitro conditions. production of germ cells from mesenchymal stem cells is a very interesting and prom...
