GSK-3β promotes apoptosis of IL-1β-impaired BMSCs. (a)-(d) The expression level of caspase 9, cleaved caspase 9, caspase 3, cleaved caspase 3, Bax, Bcl-2, and Survivin were detected by western blotting. Flow cytometric analysis (e) and (f) and TUNEL staining (g) were performed to assess the number of apoptotic cells. All results are expressed as the (). NS: not significant, .  μm.
