Figure 2: Protective effect of SM on UVB radiation-induced apoptotic cell damage in HDFa. Cellular morphological changes were observed under a fluorescence microscope after DAPI (bright blue color) staining. UVB exposure increased apoptotic cells in HDFa. SM treatment (8, 40 and 80 µM) before UVB exposure reduced the percentage of apoptotic cells in a dose-dependent manner. values are given as means ± SD of three experiments in each group. values not sharing a common marking (a, b, c, …) differ significantly at P<0.05 (DMRT), (a) Control, (b) SM (80 μM), (c) UVB + irradiation, (d) UVB + SM (8 μM), (e) UVB + SM (40 μM), (f) UVB + SM (80 μM)
