有几种技术,可以捕捉有丝分裂过程中发生的三维空间与所需的时空分辨率。由于这些技术上的限制,我们对有丝分裂的理解,自19世纪80年代初以来一直在研究,关于有丝分裂过程及其在分子水平上的调节机制仍然是不完整的。最近开发的高分辨率类型的光片显微镜,晶格光片显微镜(LLSM),已经实现了前所未有的时空分辨率扫描的细胞内空间在全细胞水平。这项技术使以前不可能的实验成为可能(例如,跟踪每个纺锤体微管末端的生长和活细胞中单个染色体的区分),从而为有丝分裂过程的分析提供了新的途径。在这里,LLSM技术的原理进行了介绍,以及实验技术,成为可能与LLSM。此外,该技术在有丝分裂研究中的应用还有待解决的问题,大图像数据问题,提出了有助于指导有丝分裂研究进入一个新时代。
There are few technologies that can capture mitotic processes occurring in three-dimensional space with the desired spatiotemporal resolution. Due to such technical limitations, our understanding of mitosis, which has been studied since the early 1880s, is still incomplete with regard to mitotic processes and their regulatory mechanisms at a molecular level. A recently developed high-resolution type of light-sheet microscopy, lattice light-sheet microscopy (LLSM), has achieved unprecedented spatiotemporal resolution scans of intracellular spaces at the whole-cell level. This technology enables experiments that were not possible before (e.g., tracking of growth of every spindle microtubule end and discrimination of individual chromosomes in living cells), thus providing a new avenue for the analysis of mitotic processes. Herein, principles of LLSM technology are introduced, as well as experimental techniques that became possible with LLSM. In addition, issues remaining to be solved for use of this technology in mitosis research, big image data problems, are presented to help guide mitosis research into a new era.
