Cell adhesion results from specific attractive interactions between molecules on the cell surface and a substrate, which may be coated with more than one kind of molecule. Cell detachment represents the termination of these interactions by physical, chemical, electrical, optical, or other means.
WebCell Adhesion Proteins. Cell-cell adhesion is a selective process, such that cells adhere only to other cells of specific types. This selectivity was first demonstrated in classical studies of embryo development, which showed that cells from one tissue (e.g., liver) specifically adhere to cells of the same tissue rather than to cells of a different tissue … WebA working definition of a cell adhesion molecule is a cell surface receptor whose interaction with ligand is capable of ... cell adhesion molecules is usually low Ka (lo6- lo8), unlike growth factors and their receptors where the individual affinity constants are much higher 10” (figure 3a).
