Figure 5: Influence of HP on BMSCs apoptosis after I/R injury. A: Hoechst 33342 staining in the cultured BMSCs, the strong staining nucleus represent the apoptosis cells. B: The percent of apoptotic cells in normal group, I/R injury without HP group and I/R injury with 8 h-HP group. *p <0.01 vs. normal group, #p <0.01 vs. I/R group. scale bar indicates 200 μm.
