Transferase-mediated dUTP-biotin nick end labelling staining co-localization with nuclear 40,6-diamidino-2-phenylindole (DAPI) staining, original magnifications x100 and x400.
Cells positive for both transferase-mediated dUTP-biotin nick end labelling and DAPI were considered to be apoptotic. Apoptosis was increased in the rat corpus cavernosum after cavernous nerve crush without. *p < 0.05 versus the vehicle group.
