Abstract excerpt
Transforming growth factor (TGF)-beta3 is an important contributor to the regulation of medial edge epithelium (MEE) disappearance during palatal fusion. SMAD2 phosphorylation in the MEE has been shown to be directly regulated by TGF-beta3. No phospho-SMAD2 was identified in the MEE in Tgf-beta3-null mutant mice (Tgf-beta3-/-), which was correlated with the persistence of the MEE and failure of palatal fusion. In...
