Wnt6 is required for gene expression in endomesoderm cells and for the initial nuclear entry of β-catenin in macromeres. (A) Expression profile of Wnt8 and Blimp1 in controls, DnWnt6 and Wnt6 overexpressing embryos at the early blastula stage (7 hpf). (B) Expression pattern of FoxA and Gcm at the mid-blastula stage (9 hpf) in control, DnWnt6 and Wnt6-overexpressing embryos. (A,B) All embryos are in lateral view. (C) Immunostaining for endogenous β-catenin proteins in 32-cell stage control, DnWnt6 and Wnt6-overexpressing embryos.
