What do desmosomes assist in doing?

Desmosomes are specialized structures that play a crucial role in cellular adhesion, specifically by holding cells together. They are like molecular "anchors" that connect the cytoskeletons of adjacent cells, providing them with mechanical strength and stability. This structural integrity is especially important in tissues that experience significant physical stress, such as the skin. By ensuring that cells remain firmly attached to one another, desmosomes help maintain the overall integrity of the tissue, preventing cells from tearing apart during movement or stretching. This is essential for the skin's function as a protective barrier, as it allows for resilience against various external forces while maintaining a cohesive cellular structure.
