CHS induced apoptosis in breast cancer cells. (A and B) The apoptosis rate of MCF-7 and MDA-MB-231 cells measured by flow cytometry. CHS induced early apoptosis in MCF-7 and MDA-MB-231 cells. (C) Early apoptosis rate of MCF-7 and MDA-MB-231 cells treated with CHS of three independent experiments were shown in column statistics. Data are mean ± SEM of three independent experiments. *P<0.05 vs. CHS-untreated group. CHS, Clematis hederagenin saponin.
