[Abstract] To study the inhomogeneity within a cell population including exosomes properties such as exosome secretion rate of cells and surface markers carried by exosomes, we need to quantify and characterize those exosomes secreted by each individual cell. Here we develop a method to collect and analyze exosomes secreted by an array of single cells using antibody-modified glass slides that are position-registered to each single cell. After each collection, antibody-conjugated quantum dots are used to label exosomes to allow counting and analysis of exosome surface proteins. Detailed studies of exosome properties related to cell behaviors such as responses to drugs and stress at single cell resolution can be found in the publication (Chiu et al., 2016).
[摘要] 为了研究细胞群体内的不均匀性，包括外来体特征，如外来体外分泌细胞分泌速度和外来体携带的表面标志物，我们需要量化和表征每个细胞分泌的那些外来体。在这里，我们开发收集和分析由单个细胞阵列分泌的外来体的方法，使用位置登记到每个单细胞的抗体修饰的玻片。每次收集后，使用抗体缀合的量子点来标记外来体以允许外来体表面蛋白的计数和分析。在出版物（Chiu等人，2016）中可以找到与细胞行为相关的外来物质性质的详细研究，例如对药物的反应和单细胞分辨率的压力。
