Apoptotic changes in APDCs and PSFCs following irradiation. (a) A typical example of apoptosis in APDCs. As a positive control (a), APDCs were treated with 2 mM H2O2 and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) assay was performed one hour after the treatment. (b) A magnified field of the square within panel a: the arrow indicates nuclear fragmentation. (b) Apoptotic changes in APDCs and PSFCs following irradiation. TUNEL assay was performed 24 h after 8 Gy of irradiation. Nuclear staining was done with DAPI. Scale: 100 μm.
