Enhancement of colony forming efficiency of UVB-irradiated HaCaT cells by NG. HaCaT cells were much-irradiated or irradiated with 15 or 30 mJ cm−2 of UVB. The cells were left untreated or treated with 5 or 10 µm NG. Six hours after NG treatment, cells were washed twice with PBS, trypsinized, reseeded and incubated in fresh medium for 14 days. Cell survival was assessed by counting the number of colonies following different treatments. *Shows significant difference from UV-treated cells at P < 0.05.
