AB  - Background: The specific effect of SV40T on neurocytes has seldom been investigated by the researchers. We transfected Schwann cells (SCs) that did not have differentiation ability with MPH 86 plasmid containing SV40T, in order to explore the effects of SV40T on Schwann cells. Methods: SCs were transfected with MPH 86 plasmid carrying the SV40T gene and cultured in different media, and also co-cultured with neural stem cells (NSCs). In our study, SCs overexpressing SV40T were defined as SV40T-SCs. The proliferation of these cells was detected by WST-1, and the expression of different biomarkers was analyzed by qPCR and immunohistochemistry.Results: SV40T induced the characteristics of NSCs, such as the ability to grow in suspension, form spheroid colonies and proliferate rapidly, in the SCs, which were reversed by knocking out SV40T by the Flip-adenovirus. In addition, SV40T up-regulated the expressions of neural crest-associated markers Nestin, Pax3 and Slug, and down-regulated S100b as well as the markers of mature SCs MBP, GFAP and Olig1/2. These cells also expressed NSC markers like Nestin, Sox2, CD133 and SSEA-1, as well as early development markers of embryonic stem cells (ESCs) like BMP4, c-Myc, OCT4 and Gbx2. Co-culturing with NSCs induced differentiation of the SV40T-SCs into neuronal and glial cells. Conclusions: SV40T reprograms Schwann cells to stem-like cells at the stage of neural crest cells (NCCs) that can differentiate to neurocytes.
