The apoptosis of cells in co-culture. a, b The immunocytochemistry staining for caspase-3 (brown) in apoptotic BMSCs (a) and SnChos (b, arrows) in co-culture at 7 and 21 days. Bars = 100 μm. The ratio of caspase-3-positive cells was calculated (right, n = 3). c, d The expression level of Bax and Bcl-2 in BMSCs (c) and SnChos (d) in co-culture at 7 and 21 days (n = 3). The BMSCs (7d) or SnChos (7d) were used as control. *P < 0.05, **P < 0.01002E
