Difference in XTcf-3 dependency accounts for change in response to beta-catenin-mediated Wnt signalling in Xenopus blastula

Wnt signalling functions in many tissues and during different stages of animal development to produce very specific responses. In early Xenopus embryos there is a dramatic change in response to Wnt signalling within only a few hours of development. Wnt signalling in very early embryos leads to a dor...
