Figure 2. Art treatment promotes cell viability and inhibits apoptosis in UVB-irradiated HaCaT cells. (A) CCK-8 of the growth rate of HaCaT cells in control group, UV group, UV + 1 μg/ml Art group, UV + 5 μg/ml Art group and UV + 20 μg/ml Art group. (B, C) Flow cytometry of apoptotic levels in each group. (D, E) Hoechst/PI staining for morphological changes of HaCaT cell apoptosis in each group. Scale bar: 100 μm. Magnification: 200×. *p<0.05; ****p<0.0001.
