Regional differences in the topography of the zebrafish cone mosaic. (A) Montage of five en face images of the adult zebrafish UV cone sublamina. Scale bar = 200 ยตm. Cropped images of the (B) peripheral adult growth and (C) parapapillary larval growth, showing differences in the percentage of six-sided cells within the cone mosaic. The corresponding Voronoi diagrams indicate the number of sides for each Voronoi cell (purple = 4; light blue = 5; green = 6; yellow = 7; red = 8; dark blue = 9). (D) The peripheral adult growth (blue box in A) shows a regular, crystalline mosaic, indicated by the high number of six-sided Voronoi cells (green cells). (E) In contrast, the parapapillary larval growth (orange box in A) shows disorganized, random packing.
