The extracellular matrix (ECM) is a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. Key components of the ECM include collagen, which gives strength and structure, and elastin, which allows tissues to stretch and return to their original shape. Other important elements are glycoproteins and proteoglycans, which help in cell signaling and maintaining hydration. The ECM plays a crucial role in tissue development, repair, and overall function. It influences cell behavior, including migration, proliferation, and differentiation. Additionally, the ECM is involved in wound healing and can affect the progression of diseases, such as cancer, by altering the cellular environment.
