Fig. 5

Genetic interactions between tag1 and stbm. All panels show dorsal views of the hindbrain with anterior to the left. Tg(isl1:gfp) embryos were fixed at 48 hpf, and processed for immunohistochemistry with zn5 antibody (red) to label dorsal commissural neurons and axons at rhombomere boundaries, and anti-GFP antibody (green) to label FBMNs (arrowheads). (A) FBMNs migrate normally in a control embryo. (B, C) Partial loss of FBMN migration in embryos injected with suboptimal dose of tag1 MO (B) or stbm MO (C). (D) Complete loss of FBMN migration in an embryo injected with suboptimal doses of tag1 and stbm MOs. (E) Partial loss of FBMN migration in a trilobite^tc240a (tri) heterozygous (stbm +/-) embryo. (F) Complete loss of FBMN migration in a trilobite heterozygote injected with suboptimal dose of tag1 MO. Scale bar in F (75 μm for A–F).
