<p><b>A:</b> Labeling of nuclei with DAPI (blue) and of cone photoreceptor outer segments and terminals (arrowheads) with peanut agglutinin (green) on retinal cryostat sections of wild-type, ΔEx14–17, and I756T mutant mice at 8 months. <b>B:</b> Quantification of the number of cell rows in the outer nuclear layer (ONL) from wild-type, ΔEx14–17, and I756T mutants at P28, 2 and 8 months. Values in are means ± SD. (*p<0.05; **p<0.01; ***p<0.001, ANOVA). POS, photoreceptor outer segments; OPL, outer plexiform layer. Scale bar: 10 µm.</p
