Description
Branching morphogenesis is a basic way of the kinds of complex organs’ development including lungs, kidneys, thyroid glands and salivary glands.1 Submandibular gland (SMG) development is a classic model to reveal the mechanism of branching morphogenesis and it also provides novel approaches to tissue engineering for salivary glands regenerating or for creating artificial salivary glands.And for murine salivary glands’ development, two main components are formed, epithelial and mesenchyme. The elongation and branch of epithelial make up the main process of its development which supported by mesenchymal secretion.This processes are controlled by many factors like growth factors, hormones and miRNAs etc.567 All these factors play different roles in the branching morphogenesis of mouse salivary glands. Transforming growth factor β1 (TGF-β1) is a pivotal factor of them and it has a huge impact on SMG development through its action on the mesenchyme.
