The effect of EGCG on cell viability. (A) VSMCs were incubated with 10, 50, 100, or 150 μM EGCG for 2 h and cell viability was assessed using CCK-8 assay. (B) CCK-8 assay cytotoxic effect of H2O2 on VSMCs after incubation with 50, 100, 200, 400, or 800 μM H2O2 for 30 min. Results were expressed as mean ± S.D.(n = 5). *P < 0.05 vs. control group.
