Fig. 3. Developmental expression of C3 from gastrula to organ bud stage. (A) Dorsal view of stage 10 embryo. Anterior is to the top. There is early, punctate expression of C3 in the neuroectoderm (ne); (b) blastopore. (B) Midline view of a bisected gastrula; dorsal is to the right. C3 is expressed in dorsal ectoderm and dorsal mesoderm (m). (C) Dorsal view of stage 13 embryo shows complex expression pattern in and around the neural plate (np). Anterior is to the left. (D) Sagital view of early neurula embryo shows expression in anterior endoderm (ae) and continued expression in neuroectoderm at the top. Anterior is to the left and dorsal to the top. (E) Anterior view of stage 17 embryo showing defined expression in both neural crest (nc) and neural groove (ng). Dorsal is to the top. (F) Frontal section through the embryo in (E) shows gene expression in neural crest (nc). Dorsal is to the top. (G) Stage 27 embryo shows expression in the mandibular and branchial segments of anterior neural crest. Hyoid segment is visible between the mandibular (ma) and branchial segments (br). At this stage there is strong endodermal expression (en). (H) Isolated gut tube from stage 42 embryo shows strong expression in liver and presumptive intestine, with sparing of foregut and pancreas. (f) foregut, (i) presumptive intestine, (li) liver, (lu) lung, (pa) pancreas. Image published in: McLin VA et al. (2008) Copyright © 2008.
