Figure 6

Flat-mounted retina demonstrates that the retina that was generated in the larval zebrafish is retained as a ‘larval remnant’, i.e. a relatively disorganized region of cone mosaic in the adult fish. The pattern of UV cones is more regular in the retina that was generated later, by continuous retinal growth in the adult. This transgenic zebrafish (UV cones labeled with GFP) was treated with BrdU at 7 dpf and sacrificed when 3-months-old. The lack of a row pattern of UV cones within and immediately adjacent to the ring of BrdU indicates that this ‘larval remnant’ of retina remains less organized in the adult fish. Inset shows location of the main image (gray dashed lines) within the entire retinal flat-mount.
