“…Several mass-spectrometry(MS)-based proteomic studies have found predominant ECM components in connective tissues and basal membranes, including collagen I, III, IV, VIII, XII, XIV, and XXI types, laminins, nidogens, fibronectin, vimentin, perlecan, prolargin, versican, matriline, tenascins, thrombospondin, decorin, and fibromodulin. 36 , 37 The maintenance of homeostasis and ECM turnover is involved in several factors and mechanisms. This comprises complex interactions between matrix metalloproteinases (MMP) and tissue inhibitors of matrix metalloproteinases (TIMP).…”
