The extracellular matrix (ECM) is a complex network of proteins and carbohydrates found outside of cells. It provides structural support to tissues and organs, helping to maintain their shape and integrity. The ECM also plays a crucial role in cell communication, influencing cell behavior, growth, and differentiation. In addition to providing support, the ECM serves as a reservoir for signaling molecules that regulate various biological processes. Components of the ECM, such as collagen, elastin, and glycoproteins, work together to create a dynamic environment that facilitates tissue repair and development.
