Figure 3. Inhibitory effect of BK preconditioning on hypoxia along with serum deprivation-induced apoptosis of hEPCs.

(A) hEPCs were exposed to hypoxia along with serum deprivation for 12 hours. Representative flow cytometry analysis of apoptotic cells after being labeled with annexin V and propidium iodide. (B) Quantitative analysis of the apoptotic cells (annexin V positive). Data were obtained from six independent experiments and are expressed as mean ± SEM. *P < 0.01 vs. other groups during cell apoptosis.
