Methods and devices are provided herein for identifying a cell population comprising an effector cell that exerts an extracellular effect. In one embodiment the method comprises retaining in a microreactor a cell population comprising one or more effector cells, wherein the contents of the microreactor further comprise a readout particle population comprising one or more readout particles, incubating the cell population and the readout particle population within the microreactor, assaying the cell population for the presence of the extracellular effect, wherein the readout particle population or subpopulation thereof provides a direct or indirect readout of the extracellular effect, and determining, based on the results of the assaying step, whether one or more effector cells within the cell population exerts the extracellular effect on the readout particle. If an extracellular effect is measured, the cell population is recovered for further analysis to determine the cell or cells responsible for the effect.
本文提供了用于鉴定细胞群的方法和装置,该细胞群包括产生细胞外效应的效应细胞。在一个实施方案中,该方法包括在微反应器中保留包含一个或多个效应细胞的细胞群,其中微反应器的内容物进一步包含包含一个或多个读出粒子的读出粒子群,在微反应器中培养细胞群和读出粒子群、检测细胞群是否存在细胞外效应,其中读出粒子群或其亚群提供细胞外效应的直接或间接读出,并根据检测步骤的结果确定细胞群中的一个或多个效应细胞是否对读出粒子产生细胞外效应。如果测得细胞外效应,则回收细胞群进行进一步分析,以确定产生效应的细胞。
