Effects of VPA, DEX and a combination of DEX and VPA on the apoptosis of BMSCs. After treatment with 5 mM VPA, DEX and DEX+5 mM VPA, the apoptotic rate of BMSCs was detected by flow cytometry after Annexin V-FITC and PI staining, and the apoptotic rates were calculated. *P<0.05, vs. the control, #P<0.05 vs. DEX group. FITC, fluorescein isothiocyanate; PI, propidium iodide; DEX group. BMSCs, bone marrow mesenchymal stem cells; DEX, dexamethasone; VPA, valproic acid.
