摘要: 外泌体是细胞通过胞吐过程分泌的一类粒径为30~200 nm的囊泡,其组成包括脂质双分子层以及其内部包裹的细胞来源的蛋白质、核糖核苷酸(RNA)和脱氧核糖核苷酸(DNA)等生物分子。作为一种细胞间交流的重要方式,外泌体在一系列生理和病理过程中起着至关重要的作用。由于体液环境复杂,加之自身体积小、密度低,外泌体的富集与分离对于其后续分析和功能研究至关重要。该文介绍了外泌体的研究策略、表征手段及生物学功能和临床应用研究进展,特别对外泌体的提取方法进行了详细介绍,并加以系统评述。

Abstract: Exosomes are vesicles secreted by many types of cells through exocytosis, and their sizes range from 30 to 200 nm. Exosomes consist of a lipid bilayer membrane, containing a number of bioactive molecules, e. g., proteins, ribose nucleic acid (RNA), and deoxyribo nucleic acid (DNA) derived from the cell of origin. As intercellular communication carriers, exosomes participate in many physiological and pathological processes. Because of the complexity of body fluids, as well as the small size and low density of exosomes, the isolation of exosomes is an essential and challenging step before subsequent analysis and functional studies. This review summarizes the advances in the analytical approaches, characterization methods, biological functions and clinical applications of exosomes, with particular emphasis on exosomes isolation techniques.
