A role for maternal β-catenin in early mesoderm induction in Xenopus

Mesoderm formation results from an inducing process that requires maternal and zygotic FGF/MAPK and TGFβ activities, while maternal activation of the Wnt/β‐catenin pathway determines the anterior–dorsal axis. Here, we show a new role of Wnt/β‐catenin signaling in mesoderm induction. We find that mat...
