Figure 1

Sections of retina (A–D) and cleared tissue (E). DCX positive cells (green arrows) are detected in A. burtoni retina (A) but not in zebrafish (C). Magnification of (A,C) are presented in (B,D). The proliferating cell nuclear antigen (PCNA; red arrows) binding antibodies detect cells in the peripheral germinal zone (PGZ; of both species. In addition, DCX (green arrows) and PCNA (red arrows) are detected in the ONL corresponding to cones and rod precursors, respectively. Nuclei are stained with DRAQ5 (blue). No double positive cells for DCX (green arrows) and PCNA (red arrows) are found. By analyzing the whole transparent eyeball, it is possible to follow DCX positive processes in the neural fiber layer (green arrow) into the optic nerve (E; white arrow). Scale bar 20 µm (A,C); 10 µm (B,D). ONL: outer nuclear layer; INL: inner nuclear layer; GCL: ganglion cell layer; NFL: neural fiber layer.
