Fig. 1. Effect of sericin and I-sericin or fibroin and I-fibroin on cell viability in H2O2-induced HaCaT cells.

Fig. 1

Cell viability was measured with MTT assays. (A) HaCaT cells treated with indicated concentrations of sericin and I-sericin (10–100 μg/ml) or fibroin and I-fibroin (10–100 μg/ml) for 24 h. (B) HaCaT cells treated with indicated concentrations of H2O2 (0.1–2 mM) for 24 h. (C) HaCaT cells treated with indicated concentrations of sericin and I-sericin or fibroin and I-fibroin (25–100 μg/ml) and 1 mM H2O2 for 24 h. Data are mean ± SEM (n = 3). Different label means a significant difference between each group by one-way ANOVA. *p < 0.05, compared to control. **p < 0.01, compared to control. ***p < 0.001, compared to control. #p < 0.05, compared to H2O2-only group. ##p < 0.01, compared to H2O2-only group. ###p < 0.001, compared to H2O2-only group. $p < 0.05, compared to the sericin- or fibroin-treated group.
