快速和选择性地分离具有独特空间和形态特征的单细胞仍然是一个技术挑战。在这里,我们通过建立高速图像支持的细胞分选(ICS)来解决这个问题,ICS记录荧光图像,并根据图像数据的测量结果以每秒15,000个事件的速度对细胞进行分选。我们表明,ICS量化细胞形态和标记蛋白的定位,并通过分离有丝分裂阶段增加细胞周期分析的分辨率。我们将联合收割机ICS与CRISPR合并筛选相结合,以识别NF-κB通路的调节因子,从而在大约9小时的运行时间内完成全基因组基于图像的筛选。通过评估复杂的细胞表型,ICS大大扩展了细胞分选应用和合并遗传筛选的表型空间。
Fast and selective isolation of single cells with unique spatial and morphological traits remains a technical challenge. Here we address this by establishing high speed image-enabled cell sorting (ICS), which records multicolor fluorescence images, and sorts cells based on measurements from image data at speeds up to 15,000 events per second. We show that ICS quantifies cell morphology and localization of labeled proteins, and increases the resolution of cell cycle analyses by separating mitotic stages. We combine ICS with CRISPR-pooled screens to identify regulators of the NF-κB pathway, enabling the completion of genome-wide image-based screens in around nine hours of run-time. By assessing complex cellular phenotypes, ICS substantially expands the phenotypic space accessible to cell sorting applications and pooled genetic screening.
