The Wnt signaling pathway is highly conserved in eukaryotes and is one of the most important signaling pathways. It is used extensively during animal development to regulate diverse processes including cell proliferation, differentiation, polarity, and migration, which are fundamental to embryogenesis. Wnt signals are transduced by at least two distinct pathways: the well-established canonical Wnt/β-catenin pathway and the β-catenin independent noncanonical Wnt pathway. Noncanonical Wnt signaling is very diverse and is still evolving into more and more branches. Two non-canonical signaling pathways have been well studied, the Wnt/PCP and Wnt/Ca2+...
