  • Title: [Focal contacts and the cytoskeleton].
    Author: Tint IS, Neĭfakh AA, Bershadskiĭ AD.
    Journal: Tsitologiia; 1987 Jul; 29(7):739-48. PubMed ID: 3314051.
    Abstract:
    Cultured cells attach to the substratum by means of specialized domains of cell surface, called focal contacts. The inner side of the cell membrane is associated in these structures with cytoskeletal elements, while the outer side is connected with extracellular matrix. The present review describes both light and electron microscopic methods of studying the focal contacts and ultrastructure of adhesion plaque, that is the cytoskeletal domain of focal contact. The proteins of adhesion plaque and focal contact membranes are also characterized. The processes of the formation of focal contacts and their association with the bundles of actin microfilaments in normal cultured fibroblasts are described in detail. Association of focal contacts with other cytoskeletal elements microtubules and intermediate filaments is discussed. The neoplastic transformation induced changes of focal contact system and cytoskeletal structures associated with contact sites are described.
