Fig. 7. Comparison between embryonic expressions of wdr68, ppet-1, ece-1 and ednra genes. (A) Antero dorsal view of mid-neurula stage. ppet-1 transcripts are detected in the mesoderm underlying the neural crest (asterisks) (Bonano et al., 2008). (B) Dorsal view of an embryo at neurula stage showing ece-1 expression in the lateral neural folds area (asterisks), in the ectoderm and mesoderm surrounding neural crest territory (Bonano et al., 2008). (C) Dorsal view of an embryo at neurula stage showing wdr68 expression at the cephalic region and in somitic mesoderm. (D) Lateral view of tailbud stage embryos. ednra is expressed in the branchial arches (arrow heads), in otic and optic vesicles and also in the migratory truncal neural crest streams. (E) At tailbud stages, the head shows a strong expression of wdr68, mainly at the otic and optic vesicles and in the branchial arches. At the trunk level, wdr68 is expressed in the somitic mesoderm.
