The extracellular matrix (ECM) is a vague term used to refer to all the material surrounding cells in a multicellular organism, except circulating fluids such as blood or lymph. In some cases, the ECM accounts for more of the organism's bulk than its cells. In plants, arthropods and fungi the ECM is primarily composed of nonliving material such

Extracellular matrix (ECM) is a non-cellular three-dimensional macromolecular network composed of collagens, proteoglycans/glycosaminoglycans, elastin, fibronectin, laminins, and several other glycoproteins.

3. We now know that the extracellular matrix is comprised by a large and varied group of dynamic macromolecules and their regulatory factors [1] which provides structural support and is a physical barrier. However, it also elicits cellular responses and its interactions are involved in development and organ formation [2].

Extracellular Matrix (ECM) and Adrenal Fatigue Syndrome. Internal milieu is a conceptual term coined by 19th Century French physician Claude Bernard that refers to the internal environment of an organism. According to Bernard, the cells of our bodies live under optimal and thriving conditions because they are protected from the external world.

().Among defined cell types, the extracellular matrix (ECM), a cellspecific and highly specified environment, contributes to the function, capability In biology, the extracellular matrix (ECM) 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.
