What is the Role of the Cytoskeleton in Cellular Support?
The cytoskeleton is a network of protein filaments within the cell that provides structural support, maintains cell shape, and facilitates intracellular transport. It is composed of microfilaments (actin filaments), intermediate filaments, and microtubules. The cytoskeleton interacts with the ECM through integrins and other cell surface receptors, linking the intracellular and extracellular environments.
