Territories of expression of oc genes in the zebrafish eye. On the left, schematic representation of the zebrafish eye section showing the retinal layers at 72 hpf. (A–J) In situ hybridization analysis of oc1, oc2, oc-like, oc3a and oc3b expression on zebrafish transverse eye sections at 48 hpf (A–E) and 72 hpf (F–J). oc1 expression is localized in IPL and in RGC and remains in GCL at 72 hpf (A,F). oc2 expression is observed in retinal IPL and INL at 48 hpf (B) and in GCL and ONL at 72 hpf (G), while oc-like transcript is reported in the INL and GCL at 48 hpf (C) and also in IPL at 72 hpf (H). No signal is observed for oc3a (D,I) and oc3b (E,J) in the zebrafish eye at both analyzed developmental stages. RGC, retinal ganglion cells; GCL, ganglion cell layer; INL, inner nuclear layer; IPL, inner plexiform layer; ONL, outer nuclear layer.
