Figure 5

Met is required for normal CaP axons. (a-b') Embryos at 26 hpf showing PMN axons labeled with znp1 antibody. met MO-injected embryos have normal MiP axons [arrow in (b')] compared to controls [arrow in (a')]. However, some CaP axons are truncated in met MO-injected embryos [asterisk in (b)] compared to controls (a). (c-d') Embryos at 48 hpf showing PMN and SMN axons labeled with znp1 antibody. As at 26 hpf, dorsally projecting axons in met MO-injected embryos appear normal [arrow in (d')] compared to controls [arrow in (c')]. However, some ventrally projecting axons are truncated in met MO-injected embryos [asterisk in (d)], compared to controls (c). (e) Average percentage of truncated axons in control and met MO-injected embryos at 26, 36 and 48 hpf. n (26 hpf) = 8 somites in each of 12 embryos; n (36 hpf) = 8 somites in each of 10 embryos; n (48 hpf) = 8 somites in each of 11 embryos. Scale bar, 20 μm.
