Cytoplasmic OrganellesIntercellular Junctions - Desmosomes |
|
|
| Desmosomes are special cell
junction that are characteristic of epithelial cells. The
desmosome consists of two opposing dense plaques (arrow)
on the cytoplasmic membranes. Tonofilament bundles insert
into each half of the desmosome. Amorphous material is
present in the intercellular space and often, a central
dense line can be seen. Desmosomes are characteristic of squamous differentiation. They are prominent in normal squamous epithelium and some squamous cell carcinomas. |
