Transforming growth factor-beta5 expression during early development of Xenopus laevis.

Kondaiah P , Taira M , Vempati UD , Dawid IB .

Members of the transforming growth factor-beta (TGF-beta) superfamily play various roles during development in both vertebrates and invertebrates. Two isoforms, TGF-beta2 and -beta5, have been isolated from Xenopus laevis. We describe here the localization of TGF-beta5 mRNA in early embryos of X. laevis, assessed by whole-mount in situ hybridization. The first detectable expression of TGF-beta5 was seen in the stage 14 embryo at the posterior tip of notochord, which continued to later stages, accompanied by the expression in bilateral regions of posterior wall in the tail region next to the notochord. At later stages, transient expression was seen in the cement gland (around stage 21) and in the somites (stages 24-27). In addition, expression was present in the branchial arches (stage 29-36) and olfactory placodes (stage 36).
