Fig. 3. Expression of dfna5 in zebrafish embryos using whole-mount in situ
hybridization. (A,B) 22 hpf embryo. Lateral (A) and dorsal view of the head
region (B), showing expression in the intermediate cell mass (arrowhead in A),
the olfactory placodes (arrows), ventral diencephalon and migrating neural
crest (arrows in B). (C,D) 48 hpf embryo (C) and 55 hpf embryo (D) with
expression in the developing semicircular canals of the ear (arrowheads). (E)
72 hpf embryo indicating low level of expression in the mature projections of
the semicircular canals in the ear (arrowheads). (F) Dorsal view of the ear at
48 hpf with expression at the tip of the outgrowing projections of the
semicircular canals (arrowheads). Scale bar: 300 µm in A,B; 100 µm in
C-E; 40 µm in F.
