Fig. 7. Gene expression analysis of the pharyngeal arches in
Ednrb-knock-in embryos. (A,B) Whole-mount
lacZ staining of E10.5 EdnralacZ/+ (A) and
EdnralacZ/B (B) mouse embryos. (C-L) Whole-mount in
situ hybridization for Dlx3 (C,D), Dlx5 (E,F), Dlx6
(G,H), Hand2 (I,J) and Goosecoid (K,L) in wild-type
(C,E,G,I,K) and EdnraB/B (D,F,H,J,L) embryos at E9.5
(C-H), E10.0 (K,L) or E10.5 (I,J). The expression of Dlx3, Dlx5, Dlx6,
Hand2 and Goosecoid was downregulated in
EdnraB/B arches.
