Fig. 4. Expression pattern for the wdr68 gene during Xenopus early development. (A, B) Dorsal view of embryo. (C–F) Side view. (G, H) Transverse sections. (A) wdr68 expression is ubiquitous during early stages of development. (B, C) Since the late neurula stage, there is an enrichment in its expression in the head region (black arrowhead in B), in the migratory streams of the cranial neural crest (black arrowheads in C) and in the developing somites (white arrow). (D) At stage 25, wdr68 transcripts are evident in the otic vesicle. In the somitic region (black arrow), they acquire a segmental pattern. (E, F) Since the tailbud stage, wdr68 is strongly marked in the branchial arches (brackets). (G) Front section at the level of the branchial arches (blue broken line in F). Notice that the ectodermal cell population corresponding to the neural crest expresses wdr68. (H) Transverse section at the trunk level (red broken line in F). wdr68 expression is evident on the floor of the neural tube and in somitic mesoderm.

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.
