Desmosomes are specialized structures that help cells adhere to one another, providing mechanical strength to tissues. They are particularly important in tissues that experience significant stress, such as skin and heart muscle. Desmosomes consist of protein complexes that anchor to the cell's cytoskeleton, linking adjacent cells together. These structures are formed by proteins called cadherins, which extend from one cell to another, creating a strong bond. This connection helps maintain the integrity of tissues during stretching and movement, ensuring that cells remain attached and function properly in their respective roles within the body.
