Figure 7

Effects of E. scaber, tamoxifen citrate, and their combinatorial treatment on DNA fragmentation of MCTS cultures. E. scaber ethanol extract 60 μg/mL (ES60), tamoxifen citrate 3.125 μg/mL (TC3), and tamoxifen citrate 6.25 μg/mL (TC6). The results are expressed as percentage of cells that was stained by terminal dUTP nick-end labelling (TUNEL positive). Data are presented as means ± SEM of three independent experiments. ∗Statistical significance () between control cells and treatment groups.
