Extracellular Matrix (ECM) - The ECM provides structural support to the cell and also plays a role in cell signaling. -Components: • Collagen • Glycoproteins (proteins with an oligosaccharide) • GAGs (long polysaccharide chains with amino sugars) • Proteoglycans (a core protein with one or more GAG chains connected) - Composed mostly of water. All of those proteins, glycoproteins, and proteoglycans are dissolved and assembled within a watery medium and most typically the protein ...

Alternative treatment for Osteoarthritis include: - lifestyle changes , such as losing weight to take the strain of the body's joints, and exercise to keep you active and building muscle, thereby strengthening your joints.
