<p><b>A:</b> Quantification of the percentage of TUNEL positive cells in the ONL from wild-type, ΔEx14–17, and I756T mutants at P28, 2 and 8 months. Values are means ± SD. (*p<0.05; **p<0.01; ***p<0.001, ANOVA). <b>B:</b> Immunocytochemical staining of GFAP on P28 old wild-type, ΔEx14–17, and I756T mutant retina shows more pronounced Müller cell reactivity in the I756T mutant retina. ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer. Scale bar: 20 µm.</p
