Morphological and morphometric analyses of the palate in Wnt1-Cre;Ldb1fl/-mutants. A-R) Coronal sections of the heads were stained with cresyl violet. Arrows in A-D, the distal tip of the palatal shelf. Arrow in P, a protrusion on the medial side of the palatal shelf, considered an intermediate structure for palatal shelf elevation. Abbreviation: DT, diastema tooth. Bar, 0.5 mm. S and T) Quantitative analysis of the area of the palatal shelf. The boundary of the palatal shelf used for this measurement is indicated by the dotted lines in A-L. *: p < 0.05.
