Fig. 7. Developmental expression of C9 from gastrula to organ bud stage. Anterior is to the left and dorsal to the top unless otherwise indicated. (A) Dorsal view of stage 10 embryo showing early spotted expression dorsal ectoderm. Anterior is to the top. (B) Anterior view of stage 17 embryo showing discrete neural crest (nc) and neural groove expression (ng). (C) Anterior view of stage 19-20 embryo. The three segments of the anterior neural crest show discrete expression at this stage. Mandibular segment ex- pression surrounds the presumptive eye field (e). (D) Lateral view of stage 22 embryo shows expression in mandibular (ma) and branchial segments (br) of anterior migrating neural crest. There is discrete hyoid expression noticeable between those two seg- ments. (E) Stage 27 embryo. Neural crest expression is seen in all three segments, as well as in the otic vesicle (ov), the lens (l), and the endoderm (en). (F) Stage 35 embryo shows strong liver and endodermal expression. (G) Isolated gut tube shows liver (li) and intestinal expression sparing the foregut (f), but no distal intestinal (proctodeum) expression (arrow); (lu) lung, (pa) pancreatic bud. |
