Fig. 7.

Maturation of PRCs, from precursor to 120 hpf. Different stages of PRC maturation during zebrafish retinal development. OS of the different PRC subtypes are highlighted in magenta (UVS cones), yellow (rods), blue (SWS cones) and red (LWS cones). This schematic depicts the size of the cell body, IS and OS height and OS width (the same arbitrary scale is used for all stages, with the exception of the synapses). Nuclei are represented in grey (eu- and heterochromatin represented in light and dark grey, respectively). Mitochondria and ER (in the IS of rods at stage 3 and 4) are shown in the IS of PRCs. OLM is marked by a green dash line.
