它在细胞分裂之前复制，其中一个中心粒移向细胞的另一端，组织纺锤体和中心体。
Prior to cell division it replicates, and the sister centrioles move to opposite ends of the cell to lie within the spindle - organizing structure, the centrosome.
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。
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.
