Caption Absence of an endocardial/endothelial lineage in Etv2Gt(141.1H7)Cmhd/Etv2Gt(141.1H7)Cmhd heart and embryo. (Top) Morphological appearance of E8.5 wild-type (+/+, WT) and Etv2Gt(141.1H7)Cmhd/Etv2Gt(141.1H7)Cmhd (-/-) embryo littermates. Note that the whole-mount WT and null embryos are indistinguishable at E8.5. (Middle) Histological analyses of the WT and null embryo demonstrating an absence of the endocardial/endothelial lineage (End) and vasculature (PHV, primary heart vein; DA, dorsal aorta) in the null embryo compared to WT littermate. (Bottom) Immunohistochemical analysis of alpha-endomucin in the WT and null embryo further demonstrating an absence of the endocardial/endothelial lineage (arrowhead shown in WT) and an absence of the vasculature in the null embryo. A higher magnification field reveals an absence of endocardium in the null heart compared to the WT littermate (alpha-endomucin expressing endocardium indicated by an arrowhead).
