Expression patterns of foxa1/2/3 and gata4/6 in the endoderm. (A-E) Expression patterns of foxa1 (A), foxa2 (B), foxa3 (C), gata4 (D) and gata6 (E) at 26, 30, 38 and 48 hpf show that expression of these genes in the endoderm is fairly static at least during these stages. foxa1 expression is in the entire endoderm, whereas foxa2 and foxa3 expression are relatively restricted to the anterior and posterior region of the endoderm, respectively. Like foxa3, gata4 and gata6 expression appear restricted to the posterior region of the endoderm. Arrows indicate the liver. Dorsal views, anterior towards the left. Scale bar: 100 μm.
