Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Cell adhesion molecules (CAMs) are a subset of cell surface proteins [1] that are involved in the binding of cells with other cells or with the extracellular matrix (ECM), in a process called cell adhesion. [2] In essence, CAMs help cells stick to each other and to their surroundings. CAMs are crucial components in maintaining tissue structure ...
As the cell progresses along its chosen path, a given focal adhesion moves closer and closer to the trailing edge of the cell. At the trailing edge of the cell the focal adhesion must be dissolved. The mechanism of this is poorly understood and is probably instigated by a variety of different methods depending on the circumstances of the cell.
Cell junctions [1] or junctional complexes are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. [2] They also maintain the paracellular barrier of epithelia and control paracellular transport. Cell junctions ...
This cell-to-ECM adhesion is regulated by specific cell-surface cellular adhesion molecules (CAM) known as integrins. Integrins are cell-surface proteins that bind cells to ECM structures, such as fibronectin and laminin, and also to integrin proteins on the surface of other cells.
Vascular cell adhesion protein 1 also known as vascular cell adhesion molecule 1 (VCAM-1) or cluster of differentiation 106 (CD106) is a protein that in humans is encoded by the VCAM1 gene. [5] VCAM-1 functions as a cell adhesion molecule .
In this diagram, the interface between neighboring cells or the basolateral membrane is depicted as "sheets"; the space between these sheets being the extracellular environment and the location of adhesion protein interaction. Stable cell-cell interactions are required for cell adhesion within a tissue and controlling the shape and function of ...
The neural cell adhesion molecule NCAM1 appears on early embryonic cells and is important in the formation of cell collectives and their boundaries at sites of morphogenesis. Later in development, NCAM1 (CD56) expression is found on various differentiated tissues and is a major CAM mediating adhesion among neurons and between neurons and muscle.
