Extracellular Matrix Proteins are essential components of the extracellular matrix (ECM), a complex network that provides structural and biochemical support to surrounding cells. These proteins play a crucial role in tissue development, repair, and maintenance, influencing cell behavior and function. The ECM is composed of various proteins, including collagen, elastin, and fibronectin, which work together to form a scaffold that helps cells adhere, migrate, and communicate. Understanding these proteins is vital for insights into various biological processes and diseases, such as cancer and fibrosis.
