21. Cell Adhesion and the Extracellular Matrix Components of the Extracellular Matrix (ECM): The ECM is a complex community of proteins and polysaccharides surrounding cells, providing structural aid and inﬂuencing cell behaviour. Key components consist of: • Collagen: Provides tensile power. • Elas n: Allows ssues to stretch and go back to their original form. • Proteoglycans: Trap water, impar ng hydra on and cushioning. Role of Cell Adhesion Molecules (CAMs) in Tissue Forma on: CAMs are proteins on the cell ﬂoor that mediate the binding of cells to the ECM and to each diﬀerent, playing a essen al role in ssue forma on and protec on. Examples include cadherins and integrins. Func ons of the ECM in Cellular Processes: The ECM not best gives structural help however also regulates cell migra on, diﬀeren a on, and survival. It performs a key func on in wound restora on and ssue regenera on. Conclusion: The ECM and cell adhesion molecules are vital for the structural integrity and feature of ssues, inﬂuencing many elements of cell conduct.
