Wnt proteins form a family of highly conserved secreted molecules that are critical mediators
of cell-cell signaling during embryogenesis. Partial data on Wnt activity in different tissues
and at different stages have been reported in frog embryos. Our objective here is to provide
a coherent and detailed description of Wnt activity throughout embryo development. Using a
transgenic Xenopus tropicalis line carrying a Wnt-responsive reporter sequence, we depict
the spatial and temporal dynamics of canonical Wnt activity during embryogenesis. We …
Wnt proteins form a family of highly conserved secreted molecules that are critical mediators of cell-cell signaling during embryogenesis. Partial data on Wnt activity in different tissues and at different stages have been reported in frog embryos. Our objective here is to provide a coherent and detailed description of Wnt activity throughout embryo development. Using a transgenic Xenopus tropicalis line carrying a Wnt-responsive reporter sequence, we depict the spatial and temporal dynamics of canonical Wnt activity during embryogenesis. We provide a comprehensive series of in situ hybridization in whole-mount embryos and in cross-sections, from gastrula to tadpole stages, with special focus on neural tube, retina and neural crest cell development. This collection of patterns will thus constitute a valuable resource for developmental biologists to picture the dynamics of Wnt activity during development.
