The comet assay of photo-aged HaCaT cells. (A) CDSC-CNM decreases UVB-induced DNA strand break formation in HaCaT cells. To evaluate DNA damage, 50 cells (nuclei) per slide were analyzed. (B) Total damage was expressed in arbitrary units and determined as described in the materials and methods section. The data are expressed as the mean ± SD. * (P < 0.05) indicates significant differences compared with non-irradiated cells in the same concentrations of CDSC-CNM.
