Fig. 2. The effect of EC on the cell cycle in HepG2 cells. HepG2 cells were treated with different concentrations of EC for 24 h. At the end of treatment, the cells were trypsinized, incubated with RNase, stained with propidium iodide (PI), and analyzed by FCM. Data are expressed as the mean ± SD of three experiments (*p < 0.05, **p < 0.01 vs. 0 mM).
