Abstract：
:Actin filaments, microtubules, and intermediate filaments, have all been found to be dynamic structures in living cells. Recent studies have shed important light on the assembly, disassembly, and mobility of these structures. In addition, a growing emphasis has been placed on the regulation of cytoskeletal activities by various signal transduction pathways.
