虽然荧光显微镜提供了一个重要的窗口,活标本的生理,许多生物过程太脆弱,太小,或发生太快,看到清楚与现有的工具。我们从二维光学晶格中制作了超薄光片,使我们能够在衍射极限及更高范围内以亚秒级的间隔对数百个体积的三维(3D)动态进行成像。我们将其应用于跨越四个数量级的空间和时间的系统,包括干细胞球状体中单个转录因子分子的扩散,有丝分裂微管的动态不稳定性,免疫突触,中性粒细胞在3D矩阵中的运动,以及秀丽隐杆线虫和黑腹果蝇的胚胎发生。这些结果从内心提醒我们生命系统的美丽和复杂性。
Although fluorescence microscopy provides a crucial window into the physiology of living specimens, many biological processes are too fragile, too small, or occur too rapidly to see clearly with existing tools. We crafted ultra-thin light sheets from two-dimensional optical lattices that allowed us to image three-dimensional (3D) dynamics for hundreds of volumes, often at sub-second intervals, at the diffraction limit and beyond. We applied this to systems spanning four orders of magnitude in space and time, including the diffusion of single transcription factor molecules in stem cell spheroids, the dynamic instability of mitotic microtubules, the immunological synapse, neutrophil motility in a 3D matrix, and embryogenesis in Caenorhabditis elegans and Drosophila melanogaster. The results provide a visceral reminder of the beauty and complexity of living systems.
