Integrin alpha5/beta1 mediates fibronectin-dependent epithelial cell proliferation through epidermal growth factor receptor activation.

Abstract

Human integrin alpha5 was transfected into the integrin alpha5/beta1-negative intestinal epithelial cell line Caco-2 to study EGF receptor (EGFR) and integrin alpha5/beta1 signaling interactions involved in epithelial cell proliferation. On uncoated or fibronectin-coated plastic, the integrin alpha5 and control (vector only) transfectants grew at similar… (More)
