代谢组指的是生物样本中的整套小分子或代谢物。这些分子参与许多基本的细胞内功能,反映细胞的生理状况。在单细胞水平上检测和识别代谢物并确定和监测其数量的能力,使人们能够对细胞之间的生物变异和功能异质性进行一系列令人兴奋的研究,甚至在可能是同质的细胞群体中也是如此。基于质谱、微流体和毛细管分离的单细胞代谢组学生物分析工具的开发和应用取得了重大进展。这些方法在灵敏度、特异性和通量方面的显著改进使得能够在一系列单个细胞样品中同时研究多种代谢物。
The metabolome refers to the entire set of small molecules, or metabolites, within a biological sample. These molecules are involved in many fundamental intracellular functions and reflect the cell’s physiological condition. The ability to detect and identify metabolites and determine and monitor their amounts at the single cell level enables an exciting range of studies of biological variation and functional heterogeneity between cells, even within a presumably homogenous cell population. Significant progress has been made in the development and application of bioanalytical tools for single cell metabolomics based on mass spectrometry, microfluidics, and capillary separations. Remarkable improvements in the sensitivity, specificity, and throughput of these approaches enable investigation of multiple metabolites simultaneously in a range of individual cell samples.
