Whole-mount (A–I) and sagittal section (J–L) analysis of irf6 expression in early zebrafish embryos. Ubiquitous expression is observed in 2-cell (A) and 16-cell (B) cleavage stage embryos, and in the 40% epiboly stage blastula (C). At the 80% epiboly stage (D) and bud stage (E), expression is concentrated in the forerunner cells and Kupffer′s vesicle, respectively. No expression was observed in 6-somite and 10-somite stage embryos (data not shown). At the 14-somite stage, irf6 begins to be expressed in the otic placode (F). At the 22-somite stage, additional expression in the cloaca is observed (G). At 26 hpf, lateral (H) and dorsal (I) views of whole-mounts show expression in olfactory placode, otic vesicle, and gut. Sagittal tissue sections of 26 hpf stained embryos confirm irf6 expression in the olfactory placode (J), otic vesicle (K) and gut (L). No staining signal was observed when embryos and larvae were hybridized with sense RNA probe (data not shown). cl, Cloaca; f, forerunner cell; g, gut; k, Kupffer′s vesicle; of; olfactory placode/vesicle; ot, otic placode/vesicle. |
