des·mo·some. ( des’m?-s?m) A site of adhesion between two epithelial cells, consisting of a dense attachment plaque separated from a similar structure in the other cell by a thin layer of extracellular material. Synonym (s): macula adherens. [ desmo- + G. s?ma, body], Desmosomes, also called macula adherens or anchoring junctions, are a type of intercellular junction that fastens sheets of cells together, like rivets, to increase tensile strength. They connect intermediate filaments of adjacent cells together, and important tissues where they are found include high stress tissues like skin and muscle.

A desmosome is also known as a spot desmosome or macula adherens (macula = latin for spot), because it is circular or spot like in outline, and not belt- or band shaped like adherens junctions. Desmosomes are particularly common in epithelia that need to withstand abrasion (see skin). Desmosomes are also found in cardiac cells, but the intermediate filament in this case is desmin, not.
8/5/2009 · In polarized epithelia of vertebrates, the AJ is part of the tripartite junctional complex localized at the juxta-luminal region, which comprises the tight junction (zonula occludens), AJ, and desmosome (macula adherens) aligned in this order from the apical end of the junction ( Farquhar and Palade 1963 ).
10/23/2009 · Desmosome ( macula adherens ) A patchlike junction found between adjacent cells in epithelial tissues that helps strengthen the tissue by binding the cells together while allowing movement of materials within the intercellular space. It consists of a discrete cluster of fibres running across a space, some 25 nm wide, between the two cells.
