Figure 2. Expression of class-3 semaphorins in Xenopus laevis. Gastrula, neurula, and tadpole stage Xenopus laevis embryos were analyzed by whole mount in situ hybridization. Rows represent the expression pattern of the semaphorin indicated at the left side. Columns show different stages of Xenopus laevis development. Gastrula stage 11-12 embryos are shown with the dorsal side up. Neurula stage 14-15 and the left panel of neurula stage 16-19 embryos are shown from the dorsal side. The right panel of stage 16-19 neurula embryos presents an anterior view of the embryo shown at left. ba, branchial arches; e, eye; h, heart; m, somitogenic mesoderm; mh, midbrain hindbrain boundary; nt, neural tube; no, notochord; s, somites; sm, splanchnic mesoderm.
