Epithelial-Mesenchymal Transition (EMT) is the trans-differentiation of stationary epithelial cells into motile mesenchymal cells. During EMT, epithelial cells lose their junctions and apical-basal polarity, reorganize their cytoskeleton, undergo a change in the signaling cascade that defines cell shape and reprograms gene expression. Collectively, these changes increase the motility of individual cells and enables the development of an invasive phenotype.
Fibronectin is a glycoprotein found in the extracellular matrix (ECM) that binds to integrins and other components of the ECM such as collagen and fibrin. Under normal physiological conditions, fibronectin is an important factor in cell adhesion, growth, differentiation, and migration.
Laminin is one of a large number of proteins expressed on the basal laminar of the ECM (extracellular matrix). The laminin antibody database covers several proteins, which interact with integrins and other receptor proteins to support cellular differentiation, morphology, migration, cell survival and the maintenance of tissue phenotypes. Laminin antibody studies have played a key role in research into angiogenesis and tumor development.
