Cytoskeleton has MANY roles it can: serve as a scaffold providing structural support and maintain cell shape, serve as an internal framework to organize organelles within the cell and direct cellular locomotion and the movement of materials within the cell. The cytoskeleton is made up of 3 protein filaments: actin filaments (also known as microfilaments), intermediate filaments and microtubules. The microtubules facilitate movement of vesicles between compartments. By axonal transport it facilitates the movement of neurotransmitters across the cell. Going further, there 2 major groups of microtubule motor proteins... The dynein and kinesin. Dynein is responsible for the movement of cilia and flagella; and move toward the minus end of the microtubules. Whereas, kinesins move toward the plus end of the microtubules. Hope this video helps

Smooth muscle cell migration has been implicated in the development of respiratory and cardiovascular systems; and airway/vascular remodeling. Cell migration is a polarized cellular process involving a protrusive cell front and a retracting trailing rear. There are three cytoskeletal systems in mammalian cells: the actin cytoskeleton, the intermediate filament network, and microtubules; all of which regulate all or part of the migrated process. The dynamic actin cytoskeleton spatially and temporally regulates protrusion, adhesions, contraction, and retraction from the cell front to the rear. c-Abl tyrosine kinase plays a critical role in regulating actin dynamics and migration of airway smooth muscle cells and nonmuscle cells. Recent studies suggest that intermediate filaments undergo reorganization during migration, which coordinates focal adhesion dynamics, cell contraction, and nucleus rigidity. In particular, vimentin intermediate filaments undergo phosphorylation and reorientation in smooth muscle cells, which may regulate cell contraction and focal adhesion assembly/disassembly. Motile cells are characterized by a front-rear polarization of the microtubule framework, which regulates all essential processes leading to cell migration through its role in cell mechanics, intracellular trafficking, and signaling. This review recapitulates our current knowledge how the three cytoskeletal systems spatially and temporally modulate the migratory properties of cells. We also summarize the potential role of migration-associated biomolecules in lung and vascular diseases.

Have you ever heard of the cytoskeleton? It's like a scaffold inside a cell that helps all the organelles and molecules stay in place and move around. Basically, it's like a network of tiny filaments that reach all over the cell. Scientists used to think that everything inside a cell just floated around randomly, but they were wrong! They noticed that there was an order to things and that the cytoskeleton was responsible for it. Even though it's called a "skeleton," it's actually really flexible and does more than just hold things up.

Cytoskeleton, a system of filaments or fibers that is present in the cytoplasm of eukaryotic cells. The cytoskeleton organizes other constituents of the cell, maintains the cell’s shape, and is responsible for the locomotion of the cell itself and the movement of the various organelles within it.
