Endocardial aggregation in tal1-deficient embryos does not require hand2 function. (A–D) Three-dimensional reconstructions of confocal stacks depict dorsal views of wild-type (A), han mutant (B), tal1-deficient (C) and han mutant; tal1-deficient (D) embryos expressing Tg(fli1a:negfp) (green) at 20s. (A′–D′) Reconstructions of optical sections displaying transverse slices through the endocardium of the embryos shown in (A–D). Arrowheads mark progenitors of the lateral dorsal aortae. The endocardium forms a single-layered sheet in wild-type (A and A′) and han mutant (B and B′) embryos. In contrast, the endocardium in embryos that are deficient for both han and tal1 (D and D′) forms a multi-layered aggregate similar to that seen in tal1-deficient embryos (C and C′). |
