Figure 4

Initial patterning of the arches is maintained in barx1 morphants. (A, C, E and G) control MO injected embryos, (B, D, F and H) embryos co-injected with Bx MO + Sa MO, 2 ng each. Neural crest expression of inca (A, B) and dlx2a (C and D) at 24 hpf. (E, F) neurod expression at 24 hpf in neural ganglia precursors; (G and H) hand2 expression in ventral endoderm at 32 hpf. Neural crest streams marked in Roman numerals, gill arches indicated by numbers; e, eye; m, mandibular arch; h, hyoid arch; ov, otic vesicle; ad/av/f, anterodorsal/anteroventral lateral line/facial placode/ganglia; o, octavel/statoacoustic ganglia precursors; p, posterior lateral line placode/ganglion. Scale bar: 100 μm.
