Fig. 1 Laterality defects in laf/alk8 mutant embryos. (A–C) Wild-type sibling (A) and laf/alk8 mutant (B) embryo at 30 hpf stained for cmlc2 expression to reveal positioning of the heart and quantification of the results (C). (D–G) Wild-type sibling (D) and laf/alk8 mutant (E, F) embryos at 50 hpf stained for foxa3 expression to reveal the positioning of the liver (l), pancreas (p) and gut (g) and quantification of the results (G). (H–K) Wild-type sibling (H) and laf/alk8 mutant (I, J) embryos at 22 somite stage stained for lefty1 expression in the dorsal diencephalon and quantification of the results (K). All pictures are of dorsal views with anterior to the top (M, middle; L, left; R, right; B, bilateral; A, absent).
