Fig. 2. Expression of a-tubulin in the skin of Xenopus embryos at different developmental stages.
Expression of a-tubulin detected by whole-mount in situ hybridization on Xenopus embryos at stage 13
(A-C), stage 16 (D-F) and stage 20 (G-I). Dorsal views (A,D,G) and lateral views (B,E,H) show that a-
tubulin expression occurs in the non-neural ectoderm (nne) and not in the neural plate (np). Expression
is also absent from the cement gland (cg). (C,F,I) Sections of whole-mount-stained embryos show that
cells expressing a-tubulin are located in the inner layer (parenthesis or arrow labeled “i”) at stage 13,
and in the outer layer (brackets labeled “o”) at stage 16 and older, indicating that the ciliated cells first
arise in the inner layer before stage 13 and then subsequently move into the outer layer. Image published in: Deblandre GA et al. (1999) Copyright © 1999.
