Fig. 7. Neural crest expression of G37 in neurula and tailbud Xenopus embryos. A: Lateral view of a stage 15 embryo. Arrowheads indicate staining of cranial neural crest. B: Dorsal view of A. G37 expression is seen in the most anterior cranial neural crest. Segregation into individual neural crest segments (arrowheads) has begun. C: Lateral view of a stage 21 embryo. G37 mRNAs are now found in cranial (m, mandibular crest; h, hyoid crest; ab, anterior branchial; pb, posterior branchial), and truncal (1) neural crest segments. The periphery of the eye vesicle (ev) is populated by mandibular (m) neural crest expressing G37 mRNA. D: Dorsal view of C to illustrate expression of G37 mRNAs in the posterior branchial arch segment (pb), and in truncal (1) neural crest. E: Lateral view of a stage 27 embryo. Expression of G37 mRNAs in all cranial neural crest segments and in truncal (1) neural crest of the dorsal fin. F: Close-up view of E at higher magnification to illustrate expression in cranial and truncal neural crest (see C for labeling). Neural crest derivatives were labeled according to the nomenclature of Sadaghiani and Thiebaud (1987). Scale bars: A, B = 160 pm; C, D = 144 pm; E = 225 pm; F = 112.5 pm.
