Loss of pax3 leads to a decrease in mitfa expression. (A-C) Medaka embryos at stage 28 (30 somite). (D-F) Zebrafish embryos at 19.5 hpf (21 somite). Arrowheads indicate the posterior ends of mitfa expression in the neural crest (D-F). Lateral views at top and dorsal views at bottom. The mitfa-expressing cells were largely lost in the absence of Pax3 in medaka (A,B) and in zebrafish (D,E). Those cells appeared to be normal or rather increased in the medaka pax7a mutant (C) and in the zebrafish pax7a; pax7b double mutant (F). Images are representative of more than ten embryos. Scale bars: 250 µm.
