Fig. 1 Zoep and ntl are not required for the formation of cardiac mesoderm or vascular endothelium. Anterior, left; dorsal, uppermost; genotypes as indicated (bottom left) (A?D) flk-1 expression. Note the presence of flk-1 expressing cells in the Zoep;ntl embryo, which are disorganized and possibly more numerous than in wild-type or either single mutant embryos. (E) Myosin staining (brown) detects the cardiac primordium (arrow), as well as somitic tissue in the anterior trunk, as previously reported.
