摘要: 传统荧光显微镜由于对某些荧光分子存在光毒性、光损伤等方面的缺陷,无法满足对部分活体样本进行长时间观测的需求。光片荧光显微镜(light sheet fluorescence microscope,LSFM)是一种新型荧光显微镜,有别于激光共聚焦显微镜,其特殊的正交光路设计和高效的信号采集装置,使其具备低光毒性、低光漂白、低光损伤和高时空分辨率等优良特性,从而能对细胞及大尺度生物组织样本进行时空连续性较好的记录,尤其适宜于活体生物样品。基于此,概述了光片荧光显微镜的成像原理、成像优势、成像效果的改进与优化历程及其在生命科学领域应用所取得的研究成果,重点对近三年相关应用进行了汇总,并简要介绍了其在神经生物学、发育生物学、动物细胞生物学和植物科学领域中一部分代表性研究内容,最后,总结了光片荧光显微镜的优点与发展至今仍存在的不足,并对其在光遗传学和多组学研究中的潜在应用进行了展望,以期为研究人员提供较为系统的光片荧光显微镜相关基础知识、最新的研究应用进展以及未来的潜在应用方向,为研究人员提供参考。

Abstract: Conventional fluorescence microscopes are unable to meet the demand for prolonged observation of live samples with some certain fluorescence signal molecules due to their high phototoxicity, phtodamage, etc. As a novel fluorescence microscope, light sheet fluorescence microscope(LSFM) has outstanding characteristics which are different from laser scanning confocal microscope, such as the low phototoxicity, low photobleaching, low photodamage and the high spatiotemporal resolution due to its special orthogonal optical path design and efficient signal acquisition device, thus it can continuously record cells and large-scale biological tissue samples, especially for the live samples. Based on this, the imaging principle, imaging advantages, improvement and optimization process of imaging effect of LSFM and its research achievements obtained in the field of life science were summarized, focusing on the related applications in recent three years, and some representative research contents in the fields of neurobiology, developmental biology, animal cell biology and plant science were briefly introduced. Finally, the advantages and disadvantages of LSFM were summarized, and its potential applications in optogenetics and multi-group studies were prospected, in order to provide researchers with systematic basic knowledge, latest research applications and potential applications in the future, and provide reference for researchers.
