Stratum spinosum
A desmosome is an adherent junction consisting of an electron-dense, proteinaceous attachment plaque into which keratin filaments insert. Proteins extend from the plaque into the intercellular space, where they overlap and provide the attachment between the cells. 70,000x

Intercellular space >
Adhesion proteins extend from the attachment plaques into the intercellular space, where they overlap with similar proteins from the adjacent cell. This overlap and the molecular interactions of the adhesion proteins provide the attachment between adjacent cells.
