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 ...
