Model Systems of Epithelium Mesenchyme Transitions

Abstract
This contribution discusses which factors bring about the transformation of epithelium to mesenchyme. Amongst biological agents which have this role are a number of cytokines (e.g. EGF, FGF-1, TGF-β, HGF/SF) and extracellular matrix macromolecules, such as collagens. The coordinated changes in cell morphology, associated with the induction of cell motility and the loss of intercellular junctions, are under the control of signaling molecules that transduce the signal emanating from the plasma membrane, which ultimately lead to changes in gene expression.
