title: Expression of Axwnt-8 and Axszl in the urodele, axolotl: comparison with Xenopus.
abstract: In both the urodele axolotl and the anuran Xenopus, Wnt-8 is expressed in posterior lateral plate mesoderm (LPM) in neurula and tailbud stages. In contrast to Xenopus, expression in axolotl is more prominent in gastrula endoderm, is not initiated in mesoderm until late gastrulation, and is present in the tailbud and in the brain at tailbud stages. Sizzled is expressed in axolotl in the ventral region, similar to its pattern in Xenopus. In axolotl, the Wnt-8-expressing LPM remains relatively dorsal through tailbud stages, while ventral blood island (VBI) markers appear in a wide ventral arc.
