The extracellular matrix (ECM) is a complex network of proteins and polysaccharides that provides structural and biochemical support to cells. The major components of the ECM include collagen, elastin, glycoproteins, and proteoglycans. Collagen provides tensile strength, elastin allows tissues to resume their shape after stretching, glycoproteins facilitate cell adhesion, and proteoglycans contribute to the ECM's hydration and resilience.
