In biology, the extracellular matrix (ECM) is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells. Because multicellularity evolved independently in different multicellular lineages, the composition of ECM varies between multicellular structures; however, cell adhesion...

(from the article `cell`) A substantial part of tissues is the space outside of the cells, called the extracellular space. This is filled with a composite material, known as ... Another type of adhesion that keeps cells in place is their attachment to the extracellular matrix, the network of substances secreted by cells and ... [2 re...

Any material produced by cells and secreted into the surrounding medium, but usually applied to the noncellular portion of animal tissues. The ecm of connective tissue is particularly extensive and the properties of the ecm determine the properties of the tissue.

A complex network of fiber-forming proteins interwoven in a hydrated polysaccharide gel that helps hold cells and tissues together and provides a meshwork for cells to migrate on and interact with one another. The extracellular matrix influences cell development, migration, proliferation, shape and metabolic functions.

(= ecm; ECM) Any material produced by cells and secreted into the surrounding medium, but usually applied to the non-cellular portion of animal tissues. The ecm of connective tissue is particularly extensive and the properties of the ecm determine the properties of the tissue. In broad terms there are three major components: fibrous elements (particularly collagen, elastin, or reticulin), link proteins (eg. fibronectin, laminin), and space-filling molecules (usually glycosaminoglycans). The matrix may be mineralised to resist compression (as in bone) or dominated by tension-resisting fibres (as in tendon). The basal lamina of epithelial cells is another commonly encountered ecm. Although ecm is produced by cells, it has recently become clear that the ecm can influence the behaviour of cells quite markedly, an important factor to consider when growing cells in vitro : removing cells from their normal environment can have far-reaching effects.

(ECM) Region outside of metazoan cells which includes compounds attached to the plasma membrane, as well as dissolved substances attracted to the surface charge of the cells. The ECM functions both to keep animal cells adhered together, and well as buffering them from their environment.
