Molecular control of gonadal differentiation within the chicken embryo
When you look at the embryo that is mammalian two important ovarian pathways have already been defined. The initial requires the canonical ?-catenin signalling path. In this pathway, ovarian signalling particles R-Spondin 1 (Rspo1) and Wnt-4 activate the ?-catenin pathway into the developing feminine gonad (Fig. 2 ).
