Fig. 8

Barx1 expression in fgf mutant embryos. (A, B) Wild-type sibling and lia/fgf3 mutant. Arrows indicate sites of barx1 expression in the gill arches. (C–E) Wild-type sibling and left and right views of an ace/fgf8 mutant embryo. Left/right asymmetric expression indicated in the mutant (arrowhead); asterisk indicates reduced expression in the third gill arch. (F, G) Overstained control (DMSO) and embryo treated with the FGF receptor inhibitor SU5402 from 24 hpf to 48 hpf. Lateral views with anterior to the left, panel D was flipped for comparison; d, dorsal and v, ventral expression domains of the second arch; e, eye; gill arches are numbered; g, gut primordium; h, hyoid arch; m, mandibular arch; ov, otic vesicle. Scale bar: (A–G) 50 μm.
