Abstract (original English)

Mesenchymal stem cells (MSCs) are converted to neural cells using growth factors and chemicals. Although these neural cells are effective at modulating disease symptoms, they are less effective at replacing lost neural cells. Direct transdifferentiation seems to be a promising method for generating the required cells for regenerative medicine applications. Sox2 is a key transcription factor in neural progenitor (NP) fate determination and has been frequently used for transdifferentiating different cell types to NPs. Here, we demonstrated that the overexpression of a single transcription factor, Sox2, in human adipose tissue-derived mesenchymal stem cells (hAT-MSCs) led to the generation of induced NPs-like cells that were clonogenic, proliferative and passageable, and showed the potential to differentiate into three neural lineages. NPs are known as progenitors with the potential to differentiate into oligodendrocytes. In vivo, following transplantation into demyelinated adult mouse brains, they survived, differentiated and integrated into the adult brain while participating in the remyelination process and behavioral improvement. This report introduces a beneficial, low-cost and effective approach for generating NPs from an accessible adult source for autologous applications in treating neurodegenerative diseases, including remyelination therapies for multiple sclerosis and ot
