Dose‐dependent effect of H2O2 and icariin on MC3T3‐E1 cells. (A) MC3T3‐E1 cell viability when treated with different concentrations of H2O2 (0.1 to 2 mM); (B) MC3T3‐E1 cell viability when cocultured with different doses of icariin (0.001 to 10 μM); (C) MC3T3‐E1 cell viability when cocultured with 0.2 mM H2O2 and 0.1 μM icariin from 0 to 48 h. *P < 0.05, compared with the control group.
