1·The centrosome, the major microtubule organizing center regulates cell division through forming bipolar mitotic spindles and plays an essential role in the maintenance of chromosomal stability.
中心体作为细胞的主要微管组织中心，在细胞周期过程中建立两极纺锤体，调节细胞有丝分裂，从而对维持染色体的稳定起着重要的作用。
2·Partial synchronization of cell division at anaphase-telophase has also been obtained only using HU treatment, mitotic frequency has reached at 17%.
HU对后、末期的部分同步化也有明显作用，约有17%的后、末期细胞被检测到。
