Integrin and ECM functions: roles in vertebrate development.
The analysis of mutant mice is bringing novel insights on the role of extracellular matrix (ECM) and integrin receptors during a variety of physiological processes, including embryonic development. The requirement of these adhesion molecules in epithelial morphogenesis or histogenesis in organs such as kidneys and lungs, in limbs, and in the development of mesoderm and the nervous system has been unraveled by the study of single or compound mutants. Their role in tissue integrity has also been highlighted. Models have been produced that should prove very useful in defining the cellular mechanisms and the functions of integrins and ECM signaling cascades in vivo.
