许多研究都强调了动物细胞中单个微管(MT)阵列的自定心活动,但相对较少的工作涉及在共同细胞质中共存的多个阵列的行为。在多核盘基网柄菌细胞中,每个中心体组织一个放射状的 MT 网络,并且这些网络彼此保持分离。这一特征提供了揭示负责多个中心体定位的机制的机会。使用激光微束消除双核细胞中的两个中心体之一,我们发现未改变的阵列快速重新定位在细胞中心。这一结果表明,每个 MT 阵列不断受到对中力的作用,并推断出一种平衡多个阵列位置的机制。我们的结果解决了已知对维持 MT 组织有影响的三种驱动蛋白和交联 MAP 的有限作用,并提出了一种用于保持阵列分离的简单方法。
Numerous studies have highlighted the self-centering activities of individual microtubule (MT) arrays in animal cells, but relatively few works address the behavior of multiple arrays that coexist in a common cytoplasm. In multinucleatedDictyostelium discoideumcells, each centrosome organizes a radial MT network, and these networks remain separate from one another. This feature offers an opportunity to reveal the mechanism(s) responsible for the positioning of multiple centrosomes. Using a laser microbeam to eliminate one of the two centrosomes in binucleate cells, we show that the unaltered array is rapidly repositioned at the cell center. This result demonstrates that each MT array is constantly subject to centering forces and infers a mechanism to balance the positions of multiple arrays. Our results address the limited actions of three kinesins and a cross-linking MAP that are known to have effects in maintaining MT organization and suggest a simple means used to keep the arrays separated.
