Increased apoptosis contributes to retinal defects in sacs^-/- zebrafish mutants. (A) Representative TUNEL staining on retinal frozen section of zebrafish larvae at 120 hpf from control embryos and mutants. (A') Quantification of the number of TUNEL-positive cells in the entire retina based on three independent measurements of larvae per group at 120 hpf. ** p < 0.01; *** p < 0.001 were calculated by Kruskal Wallis test multiple comparisons. (B) Immunostaining of the retinal section with activated Caspase-3 antibody (green) at 120 hpf. Nuclei were highlighted with DAPI (blue). ONL, outer nuclear layer; INL, inner nuclear layer, GCL, ganglion cell layer. Scale bar = 100 μm (A) and 10 μm (B). All images were acquired using a Zeiss LSM 900 confocal-microscope. TUNEL+ cells were counted per area considering whole retina section.
