BIOB10H3 Lecture Notes - Lecture 11: Ultimate Tensile Strength, Mammary Gland, Laminin
Document Summary
The extracellular matrix (ecm: everything that surrounds the cells is part of the ecm. All of the ecm is made by cells: an organized network of extracellular materials present beyond the pm, cartilage producing cells = chondrocytes, ecm is very fibrous networks. The ecm : function: provides support to cells and tissues, give cells identity , can be sites of cell attachment, generates signals survival signals cell migration signals, can regulate cell function. Ecm sends signals to maintain cells in differentiated and functional state ex: mammary gland epithelial cells. Answer: if the collagen was processed inside the cell by enzymes then it would start to form the giant fimbrils inside the cell. This would damage the cell due to the large size. Proteoglycans: proteoglycan is a protein-polysaccharide complex composed of a mixture of. Protein and glycosaminoglycans: glycosaminoglycans (gags), gag"s are polysaccharides with the structure a-b-a-b etc.
