Wnt/β-catenin signaling plays fundamental roles in body patterning in many invertebrate and vertebrate species, by acting as a key regulator of germ layer and body axis specification. This article focuses on the roles of Wnt/β-catenin signaling in mouse early embryos, which exhibit a unique mode of development compared to non-mammalian vertebrates. Current experimental evidence suggests that Wnt/β-catenin signaling is not essential for patterning embryos before implantation. However, Wnt/β-catenin signaling regulates critical developmental events after implantation, namely the patterning of visceral endoderm, the induction of primitive streak, and the formation of anterior neural ectoderm. While Wnt/β-catenin signaling regulates the body axis formation in both mouse and frog, the mode of its action is significantly diverged between these two vertebrate species.
