Fig. 6 Expression of the posterior marker fst1 is duplicated at the anterior of the otic vesicle in the Hh inhibitor mutants. (A) Posterior otic expression of fst1 in an uki sibling embryo at 30 hpf, indistinguishable from the wild-type pattern. (B-F) In uki^-/-, lep^-/-, igu^-/- and, to a lesser extent, dre^-/- and presumed heterozygous uki sibling embryos, fst1 is ectopically expressed at the anterior of the otic vesicle at 30 hpf (arrows). Lateral views; anterior to left, dorsal to top. E is a composite of two images. Scale bars: 50 μm.
