CW 222 nm irradiation resulted in decreased cell viability in human cells in vitro 48 h post-irradiation. (A) Representative images of CV staining on Beas-2B, H1299 and HaCaT cells 48 h after CW 222 nm irradiation. A square yellow bracket indicates an irradiated area. (B) The OD of CV-stained Beas-2B cells was measured at 570 nm. Data are shown as mean ± SD from n = 3 experiments. (C) The OD of CV-stained H1299 was measured at 570 nm. Data are presented as mean ± SD from n = 3 experiments (D) The OD of CV-stained HaCaT cells was measured at 570 nm Data are presented as mean ± SD from n = 3 experiments. Where applicable, one-way ANOVA with repeated measures was performed (ns, not significant, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
