细胞生物学的一个主要目标是了解体内大分子复合物的功能组织。电子显微镜正在帮助细胞生物学家实现这一目标,这要归功于其在纳米范围内解析结构细节的能力。虽然有关标本制备,成像和图像解释的问题,使这种方法的细胞结构困难,最近的方法,设备和软件的改进,促进了重要的大分子复合物和细胞标本相对较大的体积的研究。在这里,我们描述了最近的进展,在电子显微镜的细胞和相关的方法,有助于阐明细胞结构的方式。
A major goal in cell biology is to understand the functional organization of macromolecular complexes in vivo. Electron microscopy is helping cell biologists to achieve this goal, thanks to its ability to resolve structural details in the nanometer range. While issues related to specimen preparation, imaging, and image interpretation make this approach to cell architecture difficult, recent improvements in methods, equipment, and software have facilitated the study of both important macromolecular complexes and comparatively large volumes from cellular specimens. Here, we describe recent progress in electron microscopy of cells and the ways in which the relevant methodologies are helping to elucidate cell architecture.
