F I G U R E 1 | Main steps of neural crest development in Xenopus embryos. The steps of neural crest formation are described during gastrulation, neurulation, and organogenesis. For each step, a characteristic marker expression pattern is shown. Pax3, dorsal view of a stage 14 Xenopus laevis embryo; snail2, dorsal view of a stage 18 neurula; sox10, dorsal view of a stage 22 tailbud embryo; melanocytes, one of the neural crest derivatives, side view of a tadpole. All dorsal views are shown with the anterior to the front. |
