Changes of mitochondrial membrane potential (ΔΨm) in MCTS cultures after incubation for 4 days (a) without treatment or with treatment of, (b) E. scaber ethanol extract 60 μg/mL (ES60), (c) tamoxifen citrate 3.125 μg/mL (TC3), (d) tamoxifen citrate 6.25 μg/mL (TC6), (e) ES60 + TC3, (f) ES60 + TC6. The results are expressed as fold change relative to Ψm of the untreated control group. The results are presented as means ± SEM of three independent experiments. ∗Statistical significance () between control cells and treatment groups.
