The anti-apoptotic and proliferation promoting effect of OE-FNDC5 on BMSCs subjected to H/SD injury. (A) EdU staining analysis demonstrated that OE-FNDC5 promoted the proliferation of BMSCs subjected to H/SD for 24 h. Proliferation rate = (EdU-positive nuclei/DAPI-positive nuclei) × 100%. (B) Representative flow cytometric images indicated that OE-FNDC5 decreased the apoptosis rate of BMSCs caused by hypoxia. (C) Western blot results of apoptosis proteins, Bax and Bcl2, in BMSCs with or without OE-FNDC5. *, P<0.05; **, P<0.01. Scale bar =100 µm. H/SD, hypoxia/serum deprivation; OE-FNDC5, FNDC5-overexpression; EdU, 5-ethynyl-2'-deoxyuridine.
