Multiple roles of integrins in cell motility.
Motility is essential for many important biological events, including embryonic development, inflammatory responses, wound healing, and tumor metastasis. During these events cells are in dynamic contact with the extracellular matrix through integrins. Integrins are the primary receptors for extracellular matrix proteins and consequently are required for cell motility. Cells have evolved multiple mechanisms to modulate integrin adhesive functions, which impact cell migration. In addition to providing a mechanism that allows cells to contact the extracellular matrix, integrins also promote intracellular signals that stimulate and regulate cell movement. Here we discuss the role of integrins during the multiple steps of cell migration.
