Protein expression of Schwann cell markers in differentiallyinduced BMSCs(n = 3). (A) Representative immunofluorescence micrographs showing the expression levels of Schwann cell markers (S100, GFAP, P75NGRF) in twelve experimental groups (BMSCs, BMSCs + ODM, BMSCs + RSC96-exos, BMSCs + Fb-exos, BMSCs + NSC-exos, BMSCs + ODM + RSC96-exos, BMSCs + ODM + Fb-exos, BMSCs + ODM + NSC-exos, induced BMSCs + RSC96-exos, induced BMSCs + Fb-exo, induced BMSCs + NSC-exo and RSC96) (magnification, x100). Scale bar, 50 μm. (B) Representative western blotting of the protein expression levels of S100, GFAP, and P75NGRF in the twelve groups
