Abstract (original English)
Adult stem cells could be small sources of neurons or other cellular types for regenerative medicine and tissue engineering. Recently, pluripotent stem cells have been extracted from skin tissue, which opened a new accessible source for research. To routinely obtain a high yield of functional neurons from adult human skin stem cells with defined serum-free medium, stem cells from abdominal skin were cultured in serum-free medium. To differentiate them, we used a defined medium containing growth factors. Differentiated cells were identified using the following methods: (i) Oil-red-O staining for adipocytes, immunocytochemistry with antibodies recognising (ii) neurofilaments and PGP9.5 for neural differentiation, (iii) glial fibrillary acidic protein (GFAP) for glial differentiation, (iv) Ki-67 for proliferative cells, (v) FM1-43 staining to analyse vesicle trafficking in neuronal cells and (vi) a PCR array was used. Stem cells were floating in spheres and were maintained in culture for 4 months or more. They expressed nestin and Oct 4 and were proliferative. We induced specific differentiation into adipocytes, glial and neuronal cells. The yields of differentiated neurons were high and reproducible. They were maintained for long time (1 month) in the culture medium. Furthermore, these neurons incorporated FM1-43 dye, which indicates a potent acquisition of synaptic features in n
