The Role Of Rac1 Signaling In Tissue Polarity And Branching Morphogenesis During Salivary Gland Development, Janice Jin
Biological Sciences
Salivary gland development in embryonic mouse occurs through the process of branching morphogenesis and differentiation to ultimately give rise to a fully functional, saliva-secreting adult gland. During branching morphogenesis, epithelial cells establish an apical and basal pole which determines the ultimate direction in which salivary fluid and proteins are secreted. Exactly how salivary tissue polarity is determined on a cellular and glandular level is not fully understood. Rac1, a member of the Rho GTPase family, is an intracellular signal transducer that has been shown in other cell types to regulate cell polarization. Rac1 is also important for the organization of …
