Figure 8. ARPE-19 exposed to UV radiation (@ 0.177 J/cm²). Representative confocal laser scanning micrographs showing the effect of UV radiation (0.117 J/cm²) on distributions of live (green), dead (red), and apoptotic (yellow) cells in the ARPE-19 cell culture. The yellow arrow shows a cell in early stage apoptosis. The blue arrow shows a cell in late stage apoptosis where the DNA has been fragmented.
