UVB irradiation induces nuclear hypodiploidy in IDCs.
(A) IDCs were exposed for 2 minutes to different doses of UVB, and the percentage of hypodiploid nuclei, as detected by propidium iodide staining and FACS analysis, was determined at the indicated time points. Means ± SD from 3 experiments are shown. (B) Nuclear hypodiploidy induced at 24 hours after exposure to tumor necrosis factor (200 ng/mL), FasL (1 μg/mL), TRAIL (1 μg/mL), or UVB (1 J/cm2, 2 minutes). Means ± SD from 3 experiments are shown.
