Cytoskeleton refers to a fibrous protein structure in eukaryotic organisms, and the cytoskeleton is mainly composed of microtubules, microfilaments, intermediate fibers and other materials. The cytoskeleton in a broad sense includes the nucleoskeleton, cytoplasmic skeleton, cytosolic skeleton, and extracellular matrix. The cytoskeleton plays an important role in maintaining the normal morphology of cells, withstanding certain external forces, and maintaining the normal operation of various cell functions. In addition, the cytoskeleton has other important functions, for example, the cytoskeleton can play an important function in cell division. The cytoskeleton also plays an important role in the transport of substances and the translocation of substances.
