This work presents a fully integrated microfluidic device capable of performing high-precision RT-qPCR measurements of gene expression from hundreds of single cells per run, and shows that nanoliter volume processing reduced measurement noise, increased sensitivity, and provided single nucleotide specificity.Abstract:
A long-sought milestone in microfluidics research has been the development of integrated technology for scalable analysis of transcription in single cells Here we present a fully integrated microfluidic device capable of performing high-precision RT-qPCR measurements of gene expression from hundreds of single cells per run Our device executes all steps of single-cell processing, including cell capture, cell lysis, reverse transcription, and quantitative PCR In addition to higher throughput and reduced cost, we show that nanoliter volume processing reduced measurement noise, increased sensitivity, and provided single nucleotide specificity We apply this technology to 3,300 single-cell measurements of (i) miRNA expression in K562 cells, (ii) coregulation of a miRNA and one of its target transcripts during differentiation in embryonic stem cells, and (iii) single nucleotide variant detection in primary lobular breast cancer cells The core functionality established here provides the foundation from which a variety of on-chip single-cell transcription analyses will be developedread more

TL;DR: A hydrodynamic single cell trapping and culturing platform that facilitates cell observation and experimentation using standard bio-lab equipment and leverages the stochastic position of the cells as they flow into the structured microfluidic channels, where hundreds of single cells are then arrayed in nanoliter chambers for simultaneous cell specific data collection.

Monitoring immunoglobulin heavy chain evolution in b-cell acute lymphoblastic leukemia
TL;DR: In this article, the authors proposed a method of monitoring B-cell lymphoid proliferative disorders, such as acute lymphoblastic leukemias, by measuring the presence, absence and/or levels of correlating, or index, clonotypes and related clonotype that have evolved therefrom, for example, as part of the disease condition.

TL;DR: A new, bead-based flow cytometric miRNA expression profiling method is used to present a systematic expression analysis of 217 mammalian miRNAs from 334 samples, including multiple human cancers, and finds the miRNA profiles are surprisingly informative, reflecting the developmental lineage and differentiation state of the tumours.
