Chromosome congression: another fine mesh we've gotten into.
Collecting chromosomes prior to their accurate distribution by the mitotic spindle is widely believed to be a microtubule-driven process. However, a recent study in Nature by Lénart et al. (2005) has revealed that a contractile actin network makes an essential contribution to chromosome capture in animal oocytes.
