During the G2 phase, a structure in the cytoplasm of animal cells that coordinates the formation of microtubules, called a centrosome , allows cell division to proceed during reproduction. (coursehero.com)
Studies in tissue culture cells indicate that actin- and myosin-based cortical flow is primarily responsible for driving late centrosome separation, whereas other studies suggest that actin plays a more passive role by serving as an attachment site for astral microtubules to pull centrosomes apart. (escholarship.org)
Our studies show that the dynamics of actin polymerization drive centrosome separation and this has important implications for centrosome positioning during processes such as cell migration, cell polarity maintenance, and asymmetric cell division. (escholarship.org)

In his embryos, astral microtubules, which extend out to the cortex were primarily responsible for initiating a furrow, however, smaller somatic cells seem to position the furrow through the overlapping antiparallel central spindle. (escholarship.org)
The lack of furrow formation at the central spindle then is explained by the fact that the syncytial divisions rely on a maternally supplied form of RhoGEF, RhoGEF2, lacking the specific domains that localize zygotically expressed RhoGEF (Pebble) to the central spindle. (escholarship.org)
This generates ectopic furrows strikingly similar to conventional cleavage furrows that form perpendicular to the central spindle during the syncytial divisions. (escholarship.org)
These studies demonstrate that the early Drosophila embryo is primed to form furrows at either the overlapping astral microtubules or central spindle with the shift to the latter being driven in large part by a corresponding shift from maternal-to-zygotic forms of RhoGEF. (escholarship.org)
The spindle fibers contract, pulling the chromatids towards opposite poles of the cell. (bookvea.com)
