Fig. 5. no soul/foxi1-expressing cells later disappear in the no
soul mutant. Anterior is to the left. (A-B) 36 hpf embryos labeled with
foxi1 showing that the anteriorly located foxi1-expressing
cells are absent in the no soul mutant. (C-F) 36 hpf embryos labeled
with ngn (C,D) and phox2a (E-F) showing their expression in
the visceral sensory neurons are largely absent. (G,H) 36 hpf embryos labeled
with phox2b showing that its expression in the VIIth and IXth ganglia
is absent, while its expression in the Xth ganglia appear normal in the
mutant. (I,J) 60 hpf embryos labeled with phox2a showing that the
deficits continue in the no soul mutant. AV, anterior ventral lateral
line; MHB, mid-hindbrain boundary; O, octaval/statoacoustic ganglion; OT,
oculomotor and troclear motor nuclei; VII, geniculate ganglion; IX, petrosal
ganglion; X, nodose ganglion. Scale bar: 100 µm.
