[Abstract]  The ability to conduct investigation of cellular transcription, signaling, and function at the single-cell level has opened opportunities to examine heterogeneous populations at unprecedented resolutions. Although methods have been developed to evaluate high-dimensional transcriptomic and proteomic data (relating to cellular mRNA and protein), there has not been a method to evaluate corresponding high-dimensional functionomic data (relating to cellular functions) from single cells. Here, we present a protocol to quantitatively measure the differentiation potentials of single human hematopoietic stem and progenitor cells, and then cluster the cells according to these measurements. High dimensional functionomic analysis of cell potential allows cell function to be linked to molecular ... [摘要]  在单细胞水平进行细胞转录,信号传导和功能调查的能力为以前所未有的决议研究异质人群开启了机会。 尽管已经开发了评估高维转录组学和蛋白质组学数据(与细胞mRNA和蛋白质有关)的方法,但尚未有方法从单个细胞评估相应的高维功能组学数据(与细胞功能有关)。 在这里,我们提出了一种方案来定量测量单个人造血干细胞和祖细胞的分化潜能,然后根据这些测量结果聚集细胞。 细胞电位的高维功能组分析允许细胞功能与相同祖细胞群体内的分子机制相关联。

【背景】单细胞水平的细胞转录,信号传导和功能单细胞测量技术的发展,以及流式细胞仪等先前存在的技术的发展,使得新镜头能够检测复杂的异质群体。这些方法产生大量数据,这可以借助于降维算法来解释,如使用Mpath,Monocole,PCA,Wishbone或扩散图算法在单细胞RNA-Seq上所示的(Paul等, 2016年;参见 et al。,2017),以及使用tSNE或PhenoGraph的CyTOF(Amir et al。,2013; Levine et al 。,2015)。

我们开发了这个协议,以允许在单细胞环境中对造血祖细胞的大规模培养物进行功能分析和随后的降维。在这个协议中,我们描述了在细胞因子的基质细胞培养物中培养人CD34 ...
