Figure 8. Baicalin protects cultured HDFs against UVB induced premature senescence, while has no protection for the replicative senescence.

Fibroblasts were stained for SA-β-gal and photographed under 100× magnifications (A) (C) The percentage of SA-β-gal positive cells is shown in Figure 8. (B) (D) Statistical analysis was carried out with the Student's t-test. The symbol (#) indicates a significant difference (p<0.05) between the control group and the UVB-SIPS group. Asterisks (*) indicate significant differences of p<0.05, respectively, between the baicalin-treated and UVB-SIPS cells.
