Abstract (original English)
Mesenchymal cells cultured from the vasculo-stromal fraction of adipose tissue (ADSC) show adult stem cell characteristics and several groups have claimed generating neural cells from them. However, we have observed that many markers commonly used for the identification of neural cells are spontaneously expressed by ADSC in culture. In the present study, we have examined the expression of characteristic oligodendrocyte molecules in cultured ADSC, aiming to test if myelinating cells could be generated from accessible non-neural adult tissues. In basal growth conditions, rat ADSC spontaneously expressed CNPase, MBP, MOG, protein zero, GAP43, Sox10, and Olig2, as shown by immunocytrochemistry and western blot. A small population of cultured ADSC expressed membrane galactocerebroside (O1 antibody), but no cell stained with O4 antibody. RT-PCR analyses showed the expression of CNPase, MBP, DM20, and low levels of Olig2, Sox10, and Sox2 mRNA by rat ADSC. When rat ADSC were treated with combinations of factors commonly used in neural-inducing media (retinoic acid, dbcAMP, EGF, basic FGF, NT3, and/or PDGF), the number of O1-positive cells changed, but in no case, mRNA expression of Sox10 and Olig2 transcription factors approached CNS oligodendrocyte levels. In co-culture with rat dorsal root ganglion neurons, no sign of axonal myelination by rat ADSC was observed. These studies show th
