Figure 2. The percentage of apoptotic cells is lower in the two strains with hypopigmented retinal pigment epithelium. The micrographs of the upper panel show sagittal sections of embryonic (E) day 10.5 (A), E11.5 (B), and E12.5 (C) BALB/c optic cups and those of the lower panel show sagittal sections of E10.5 (D), E11.5 (E), E12.5 (F) pJ optic cups after a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. RPE, retinal pigment epithelium; NR, neuroretina. Scale bars represent 100 μm. Arrows indicate labeled cells.
