 Staining of focal adhesions in human cell line A-431 (HPA004835)
Scale bar represents 10µm

Focal adhesions

Focal adhesions are the endpoints of the actin filaments and are used by the cell to attach to the extracellular matrix. They are also involved in cell motility and migration.

Immunofluorescent staining

Focal adhesions are localized just outside the plasma membrane and can thus be found either just under the cell or at the edge of the plasma membrane, where the cell is attached to the surface.
