(Redirected from Adhesion molecules). Cell adhesion molecules (CAM s) are proteins located on the cell surface involved in binding with other cells or with the extracellular matrix (ECM) in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings.
Adhesin: structure or macromolecule located on the surface of a cell or extracellularly that facilitates the adherence of a cell to a surface or to another cell; site of attachment is often a specific receptor, but the adherence may also be nonspecific; host cell receptors are often sugar moieties (see lectin)
