dnVegfaa exerts a dose-dependent effect on ?-cell dispersion. (A) ?-Cells (green) from 48?hpf Tg(ins:GFP) embryos with mosaic Tg(ins:dnvegfaa) expression. The percentage of ?-cells expressing dnvegfaa (magenta) is indicated, as is the severity of islet dispersion (intact, moderate or severe; white). (B) Quantification of embryos displaying varying severity of islet dispersion. (C-J) Immunostaining for insulin (?-cells, red) and endothelial cells (green) in 48?hpf Tg(fli:GFP) embryos, in combination with the indicated transgenic or mutant line, n=3-5 animals per genotype. Maximum intensity projections are presented. A, anterior; D, dorsal.
