CD44

CD44 is a protein found on the surface of many cells in the body. It plays a key role in cell communication, helping cells stick to each other and to the surrounding environment. This is important for various biological processes, such as wound healing, immune responses, and tissue repair. CD44 also acts as a receptor for hyaluronic acid, a substance that provides hydration and structure to tissues. Abnormal levels of CD44 are associated with certain diseases, including cancer, where it can influence tumor growth and spread. Overall, CD44 is essential for maintaining healthy cellular interactions and functions.
