Expression of the GATA4 and GATA6 genes in the postimplantation mouse embryo. Histological and in situ hybridization analyses performed on E5.5 (A–C) and E6.5 (D–F) murine embryos. (A) A hematoxylin and eosin-stained section through the E5.5 embryo. (B) Hybridization of the GATA4 antisense riboprobe to yolk sac visceral endoderm (VE) and parietal endoderm (PE) of E5.5 embryos. (C) Hybridization of the antisense GATA6 riboprobe to the E5.5 embryo. (D) A hemotoxylin and eosin-stained section through the E6.5 embryo. (VE) Visceral endoderm, (PE) parietal endoderm, (EC) embryonic ectoderm. (E) Hybridization of the GATA4 (E) and GATA6 (F) antisense riboprobe to E6.5 embryos.
