Caption Excessive Wnt/beta-catenin signaling results in anterior head defects during embryonic development. (A) Whole mounts of E9.5 wild-type (WT, +/+) and ApcMin/Apctm1Tno (min/fl) mutant embryos and E17.5 Apc+/Apctm1Tno(+/fl) and ApcMin/Apctm1Tno (min/fl) mutant embryos. (B) Whole mounts of E13.5 wild-type and mutant embryos of the indicated genotypes. Genetic ablation of one allele of beta-catenin in (min/fl) headless mutant (ApcMin/Apctm1Tno Ctnnb1tm4.1Wbm/Ctnnb1+) rescues normal head morphology in (min/fl; +/-) mice. (C) Histological cross sections of E12 wild-type (+/+) and mutant (min/fl) embryos. (D) Confocal cross section of E3.5-5.5 (+/fl) and (min/fl) embryos stained for beta-catenin protein. The arrowheads demarcate the outer layer (anterior visceral endoderm) of the embryo which shows increased and expanded beta-catenin expression in the (min/fl) mutant. A, Anterior; P, Posterior. (E) Whole mount in vivo X-gal staining of E16 embryos to monitor canonical Wnt/beta-catenin dependent activity in compound mutant mice harboring the corresponding BAT::gal reporter transgene. Genotypes are as follows: wild-type (+/+); Apc+/fl (+/fl); Apcfl/fl (fl/fl); Apcmin/+ (min/+); Apcmin/fl (min/fl); Apcmin/fl;Ctnnb1+/- (min/fl; +/-).
