EXTRACELLULAR MATRIX Department of Natural Sciences University of St. La Salle Bacolod City 2. It contains high quantities of water, several types of cells, and a fibrous extracellular matrix.The connective tissue of an organ is usually referred to as the stroma.This tissue type can have very different structures according to the proportions of its components. It provides a substrate for cell anchorage, serves as a tissue scaffold, guides cell migration during embryonic development and wound repair, and has a key role in tissue morphogenesis. Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM. en.wiktionary.2016 Connective tissue is found between other tissue types and organs. 19.03.16 Saradbrata Mishra 319.03.16 Saradbrata Mishra DEFINITION • Extracellular matrix (ECM) is a network of interstitial proteins that constitutes a significant proportion of any tissue. extracellular matrix.
