These cells can introduce an accessible autologos source of neural precursor cells for treatment of different neurodegenerative diseases. This research was done in order to set up isolation, culture, proliferation and differentiation of human skin derived precursors (hSKPs)."n"nMethods: Human foreskin samples were cut into smaller pieces and cultured in proliferation medium after enzymatic digestion. To induce neural differentiation, cells were cultured in neural differentiation medium after fifth passage. We used immunocytochemistry and RT-PCR for characterization of the cells. Neuron and glial cell differentiation potential was assessed by immunofloresence using specific antibodies. The experiments were carried out in triplicate."n"nResults: After differentiation, βΙΙΙ- tubulin and neurofilament-M positive cells were observed that are specific markers for neurons. Moreover, glial fibrillary acid protein (GFAP) and S100 positive cells were identified that are markers specifically express in glial cells. Detected neurons and glials were also confirmed by their morphologic characterizations."n"nConclusion: Our results demonstrated that skin-derived precursors obtained from human foreskin can exhibit neuronal and glial differentiation potential in vitro, depending on the protocols of induction.
