Asymmetric cell division (ACD) is a strategy for achieving cell diversity. Research carried out over the last two decades has shown that in some cell types that divide asymmetrically, mother and daughter centrosomes are noticeably different from one another in structure, behaviour, and fate, and that robust ACD depends upon centrosome function. Here, I review the latest advances in this field with special emphasis on the complex structure-function relationship of centrosomes with regards to ACD and on mechanistic insight derived from cell types that divide symmetrically but is likely to be relevant in ACD. I also include a comment arguing for the need to investigate the centrosome cycle in other cell types that divide asymmetrically.
不对称细胞分裂(ACD)是一种实现细胞多样性的策略。过去二十年的研究表明,在一些不对称分裂的细胞类型中,母细胞和子细胞的中心体在结构、行为和命运上明显不同,而强大的 ACD 取决于中心体的功能。在这里,我回顾了这一领域的最新进展,特别强调了中心体与 ACD 相关的复杂结构-功能关系,以及从对称分裂但可能与 ACD 相关的细胞类型中获得的机制见解。我还包括了一条评论,认为有必要在其他不对称分裂的细胞类型中研究中心体周期。
