FOXE1 expression in developing chicken embryos. Antero-lateral views showing whole mount in situ hybridization localization of FOXE1 transcripts in chicken embryos at stages 14 (A), 17 (B), and 18 (C); anterior view of the embryonic pharyngeal arches at stage 25 (D). Transverse sections showing FOXE1 expression at stages 14 (E), 17 (F), and 35 (G). In situ hybridization showing the localization of the thyroid expressed gene HHEX stages 14 (H) and 35 (I). FOXE1 is expressed in distal growing feathers by HH stage 42 (J).
