   Abstract:
   Four processes involve in the formation of new cytoskeletal network and its disassembly have been discussed, which include crawling inside a pipet, phagocytosis, polymerization inside tethers, and pseudogrowth. Network formation and disassembly are thus coupled, and determine the network dynamics. This dynamics, however, cannot be characterized directly; the experimentally measured parameters that is closely related to it is the advancement of network front or network 'boundary'. Accordingly, the front advancement along a tether is studied for different temperatures for a medium containing Ca²⁺ and for Ca²⁺-free medium. The slope of the Arrhenius plot of this dependence is hence related to the activation energy of network formation.
