Actin networks in cell migration and organization of nascent adhesions and focal adhesions. Left, scheme of a migrating cell displaying characteristic actin structures: lamellipodial and filopodial actin networks and the three classes of stress fibers (transverse arcs, dorsal stress fibers, ventral stress fibers). Right, actin-binding proteins in focal complexes and focal adhesions. PM, plasma membrane; ECM, extracellular matrix.
