Figure 1. Apoptotic cells are stained with terminal deoxynucleotidyl TUNEL in groups. TUNEL-positive cells reflective green immunofluorescence. Positive apoptotic cells were counterstained with DAPI nuclear staining. There were many apoptotic cells in group 2. There were only a few TUNEL-positive cells in the ovaries of group 3 (Original magnification, 400x) DAPI: 4',6-diamidino-2-phenylindole, TUNEL: Transferase-mediated dUTP nick end labeling.
