Fig. 5From: β-catenin is required in the neural crest and mesencephalon for pituitary gland organogenesisImmunostaining for β-CATENIN (green) on e14.5 sagittal sections, counterstained with DAPI (blue) a–c Wild type, boxed regions in a are magnified in b and c. b Region highlighting neural crest derived mesenchyme c Region highlighting ventral diencephalon d–f Wnt1-cre; β-cat fx/fx, boxed regions in d are magnified in e and f. e Region highlighting neural crest derived mesenchyme where β-CATENIN is lost f Region highlighting ventral diencephalon where b-catenin is maintained. Arrow indicates a small region with no β-CATENIN expression. Scale bars in a and d equal 100 μm, scale bars in b, d, e, and f equal 20 μmBack to article page
