PLAY. extracellular matrix Non-living material secreted by cells that fills spaces between the cells in a tissue, protecting them and helping to hold them together. Extracellular matrix is a general term for the extremely large proteins and polysaccharides that are secreted by some cells in a multicellular organism, and which acts as connective material to hold cells in a defined space. The extracellular matrix is comprised of non-cellular components within tissues that form an essential scaffold for cellular constituents. When a molecule within the matrix binds to the receptor, it changes the molecular structure of the receptor. Anonymous.
