WebCell–ECM adhesion proteins, actin cytoskeleton, and ECM stiffness evidently play a major role in driving cancer cell invasion and metastasis being involved in virtually all steps of the metastatic process from cell dissociation from the original tumor, to invasion through surrounding ECM until the final step of cancer cell homing in the new … Focal adhesions are integrin-containing, multi-protein structures that form mechanical links between intracellular actin bundles and the extracellular substrate in many cell types. Focal adhesions are large, dynamic protein complexes through which the cytoskeleton of a cell connects to the ECM. They are limited to clearly defined ranges of the cell, at which the plasma membrane closes to within 15 nm of the ECM substrate. Focal adhesions are in a state of constant flux: pro…
