Focal adhesion

(重定向自Focal adhesions)
Immunofluorescence coloration of actin (green) and the focal adhesion protein vinculin (red) in a fibroblast. Focal adhesion are visible as red dots at the end of the green bundles.

In cell biology, focal adhesions (also cell–matrix adhesions or FAs) are large macromolecular assemblies through which mechanical force and regulatory signals are transmitted between the extracellular matrix (ECM) and an interacting cell. More precisely, focal adhesions are the sub-cellular structures that mediate the regulatory effects (i.e., signaling events) of a cell in response to ECM adhesion.
