质谱流式细胞术(MC)是一种最新的技术,其将悬浮液中的细胞的基于等离子体的电离与飞行时间质谱法配对,以灵敏地定量金属同位素标记的亲和试剂对关键蛋白质、RNA和肽的单细胞丰度。由于能够多重读出(每个细胞约50个)并在每个实验中捕获数百万个细胞,MC提供了一种强大的方法来检测与人类发育和疾病相关的罕见过渡细胞状态。在这里,我们回顾MC的方法,让我们在一个单一的实验中,在多个条件和样品类型的细胞调控的动力学探测。此外,我们还讨论了MC的当前限制和未来扩展以及通常用于从单细胞蛋白质组数据集提取生物学见解的计算工具。
Mass cytometry (MC) is a recent technology that pairs plasma-based ionization of cells in suspension with time-of-flight mass spectrometry to sensitively quantify single cell abundance of metal isotope-tagged affinity reagents to key proteins, RNA and peptides. Given the ability to multiplex readouts (~50 per cell) and capture millions of cells per experiment, MC offers a robust way to assay rare, transitional cell states that are pertinent to human development and disease. Here, we review MC approaches that let us probe dynamics of cellular regulation across multiple conditions and sample types in a single experiment. Additionally, we discuss current limitations and future extensions of MC as well as computational tools commonly used to extract biological insight from single-cell proteomic datasets.
