The Many cells, including skeletal muscle fibers, are coated by a layer of extracellular matrix material called the basement membrane (BM). They are formed of secreted proteins that associate with cell surfaces and are the most ancient animal extracellular matrix. On hydrolysis, it yields equimolecular quantities of D-Glucosamine, D-Glucuronic acid and acetic acid The framework of collagen fibrils builds up this membrane. Basement Membrane Underlying most epithelia is the basement membrane (basal lamina). The interstitial matrix is composed mainly of fibrillar collagens, proteoglycans, and glycoproteins.
