Abstract:

Abstract: African clawed frog（Xenopus laevis）, as one of the several important model organisms, has contributed significantly in our understanding of the molecular mechanisms during early embryonic development in vertebrates. One of the most important findings is the recognition that signaling pathways play key roles in regulating development. In this review we focus on the roles of Wnt signaling in Xenopus early embryos.
Key words: Xenopus; embryonic development; Wnt signaling
