Extracellular matrix

extracellular matrix: 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.
