Effect of DEPs on BeWo trophoblast viability. Cell viability is assessed after treatment with 0.05–5 μg/mL DEPs for 6, 24, and 48 h using the MTS assay. 1 mM CDSO4 is applied as a positive control for cytotoxicity. The dotted line indicates 100% viable cells. Data represent the mean percentages of viable cells compared to the untreated control (SD) of three independent biological experiments with three technical repeats each. One-way ANOVA with Tukey’s multiple comparison correction is performed to find significance between the untreated control group and different treatment groups, *p < 0.05 is considered significant.
