Fig. 5. Effect of gfra1a, gfra1b and ret antisense morpholino
oligonucleotide injection on enteric neuron development. Shown are lateral
views of the guts of 96 hpf embryos stained with anti-Hu antibody, anterior is
towards the left. Arrows indicate the end of the gut. (A) Control embryo. (B)
5 ng gfra1a morpholino injected embryo. (C) 5 ng gfra1b
morpholino injected embryo. (D) 5 ng gfra1a plus 5 ng gfra1b
morpholino injected embryo. (E) 10 ng gfra2 morpholino injected
embryo. (F) 10 ng ret morpholino injected embryo.
