Schwann Cell-Derived Exosomes Induce the Differentiation of Human Adipose-Derived Stem Cells Into Schwann Cells.

ABSTRACT: Adipose-derived stem cells (ADSCs) can differentiate into Schwann cells (SCs) at the site of nerve injury, where Schwann cell-derived exosomes (SC-Exos) are suspected to exert an induction effect. Our study aimed to induce the differentiation of ADSCs in vitro using SC-Exos and to investigate the mechanisms involved through miRNA sequencing. Subcutaneous fat was used to extract ADSCs. Exosomes were extracted from Schwann cell lines (RSC96) using ultracentrifugation and were able to be taken up by human ADSCs. After 8 days of induction of ADSCs by SC-Exos, phenotypic characteristics were observed by examining the expression of SC markers (S100ß, NGFR, MPZ, GFAP) through RT-qPCR, Western blot and immunofluorescence. The RNA and protein expression levels of S100ß, NGFR, MPZ, and GFAP w
