MicroRNA(miRNAs)是一类长度为17-25 nt的非编码RNA,在发育过程中的多种生物学过程中发挥重要作用。最近开发的miRNA微阵列技术有助于加速对miRNA的研究。然而,在某些情况下,只有有限数量的材料可用于分析,这需要更敏感的技术,可以优选地在单细胞上工作。在这里,我们证明,它是可能的,分析miRNA在单细胞中使用实时PCR为基础的220-plex miRNA表达谱方法。该技术的发展将极大地促进对细胞的miRNA相关研究,例如原始生殖细胞的创始者群体,其中在少数细胞中发生快速和动态变化,以及用于分析细胞的异质群体。在这些和类似的情况下,我们的单细胞分析方法对于阐明miRNA的不同作用至关重要。
MicroRNAs (miRNAs) are a class of 17–25 nt non-coding RNAs that have been shown to have critical functions in a wide variety of biological processes during development. Recently developed miRNA microarray techniques have helped to accelerate research on miRNAs. However, in some instances there is only a limited amount of material available for analysis, which requires more sensitive techniques that can preferably work on single cells. Here we demonstrate that it is possible to analyse miRNA in single cells by using a real-time PCR-based 220-plex miRNA expression profiling method. Development of this technique will greatly facilitate miRNA-related research on cells, such as the founder population of primordial germ cells where rapid and dynamic changes occur in a few cells, and for analysing heterogeneous population of cells. In these and similar cases, our method of single cell analysis is critical for elucidating the diverse roles of miRNAs.
