Effects of BA on the proliferation and apoptosis of HeLa cells.

<p>(A) Effect of BA towards Hela cells as determined by the MTT assay. Cells were treated with concentrations of BA (0 µmol/L, 15 µmol/L, 30 µmol/L, 50 µmol/L) for indicated time (24 h, 48 h, 72 h). The values for each BA concentration tested represent mean of three experiments, datas are presented as mean average ± SD; **<i>p</i><0.01 compared with the control group (0 µmol/L BA). (B) Hoechst 33258-staining of HeLa cells treated with 15 µmol/L, 30 µmol/L BA. Red arrows indicate several apoptotic cells with typical condensation of chromatin.
