Artwork of two desmosomes (at centre) between cells. Desmosomes form the commonest type of junction between epithelial cells, providing points of adhesion and acting as anchorage points for the cell's cytoskeleton. Plaques are seen lying beneath the membranes, and fine fibres (tonofibrils) extend into the cell cytoplasm.
