Anti-apoptotic effect of E. officinalis on UVB-irradiated NHDFs. (A) Apoptotic cells were detected by Hoechst 33258 staining. Cells that underwent apoptosis are indicated by arrows. Magnification scale: 400×. Scale bar: 10 µm; (B) Apoptotic rate was calculated as a percentage of apoptotic cells over the total number of cells numbers in five randomly selected areas. Values are means ± SD. *** p < 0.001 versus the non-irradiated control. # p < 0.05, and ## p < 0.01, and ### p < 0.001 versus the UVB-irradiated control.
