The extracellular matrix is an integral and dynamic component of all tissues. Articular cartilage is a composite tissue made of cells and fibrillar proteins embedded in a hydrophilic polymeric meshwork. Examples Of Physical Properties Of The Extracellular Matrix A Download Scientific Diagram Elastin is found in the extracellular matrix in elastic fibers which may comprise a small 2-4 but important fraction of the dry weight as in the skin or greater than 50 as in large. . The elastic properties of many tissues such as the lung dermis and large blood vessels are due to the presence of elastic fibers in the extracellular space. In biology the extracellular matrix is a three-dimensional network consisting of extracellular macromolecules and minerals such as collagen enzymes glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells. Protein collagen is made up of a matrix of carbohydrate and proteins
