Effect of CSE on HaCaT keratinocyte viability. (A) MTT assay and (B) WST-8 assay results showing the effect of CSE on HaCaT cell viability. HaCaT cells were treated with varying concentrations of CSE (0–300 µg/mL) for 24 h. CSE did not substantially reduce HaCaT keratinocytes by 200 µg/mL. Dexa:10 µg/mL. The results obtained from three independent experiments were expressed as means ± standard deviation (SD), compared with the control group. *p < 0.05 vs. control group.
