Bmp4 gene expression
Bmp4 (Bone morphogenetic protein 4) – MGI gene detail Description: Bmp4 is expressed in both epithelium and mesenchyme at E12.5. Its expression is restricted to the mesenchyme from E13.5. Bmp4 is expressed only in the anterior and distal regions of the palatal shelves. Source: Zhang et al. (2002) Rescue of cleft palate in Msx1-deficient mice by transgenic…Continue Reading Bmp4 gene expression
Beta-catenin gene expression
Beta-catenin – MGI gene detail Description: Beta-catenin is expressed in the palatal epithelium along the AP axis throughout development, including the oral and nasal epithelia and in the MEE at E14.5. Source: He et al. (2011) Epithelial Wnt/β-catenin signaling regulates palatal shelf fusion through regulation of Tgfβ3 expression. Dev. Biol. 350(2): 511-9….Continue Reading Beta-catenin gene expression
