德国海德堡欧洲分子生物学实验室Robert Prevedel团队近期取得重要工作进展。他们研究开发出用于胚胎发育过程中机械特性实时成像的高分辨率线扫描布里渊显微镜。相关研究成果2023年3月30日在线发表于《自然—方法学》杂志上。

据介绍,布里渊显微镜能以三维(3D)、全光和非接触的方式评估生物样品的机械特性,但其微弱信号往往会导致成像时间过长,并且需要对生物体有害的照明剂量。

研究人员开发出了一种高分辨率线扫描布里渊显微镜,用于低光毒性动态生物过程的多路复用和快速3D成像。改进的背景抑制和分辨率与荧光光片成像相结合,可以在果蝇、海鞘和小鼠胚胎等活体模型中可视化细胞和组织在空间和时间上的机械特性。

Abstract: Brillouin microscopy can assess mechanical properties of biological samples in a three-dimensional (3D), all-optical and hence non-contact fashion, but its weak signals often lead to long imaging times and require an illumination dosage harmful for living organisms. Here, we present a high-resolution line-scanning Brillouin microscope for multiplexed and hence fast 3D imaging of dynamic biological processes with low phototoxicity. The improved background suppression and resolution, in combination with fluorescence light-sheet imaging, enables the visualization of the mechanical properties of cells and tissues over space and time in living organism models such as fruit flies, ascidians and mouse embryos.
