Foreword
In a series of commissioned pieces, authors discuss methods for the analysis of single cells and consider technical developments still needed. Three Reviews describe methods to study single-cell gene expression, peptide, and small-molecule metabolite profiles. Two Perspectives describe live-cell imaging and clonal analysis applied to single stem cells. A Commentary provides an overview of the technological developments underlying single-cell analysis and discusses applications of genome analysis in single cells.
Single-cell analysis - Methods to study single cell genomics
Since the beginning of research on cell biology, say Stephen Quake and Tomer Kalisky in a Commentary, technological advances have driven biological understanding of the single cell. Early microscopes that permitted biologists to observe single cells have led, via molecular marking techniques and flow cytometry, to the ability to rapidly monitor dozens of markers on thousands of individual cells. But the scale of single-cell analysis has not stopped there. The authors discuss methodologies, such as microfluidics, that are enabling highly parallel genome-scale analysis at single-cell resolution. They consider new applications—including haplotyping of human cells and the analysis of complex bacterial populations—for whole-genome sequencing of single cells. (Nat. Methods 8, 311–314, 2011)
Transcriptomes - Methods for single-cell transcriptome profiling
Strategies for single-cell transcriptome analysis
Cells, even when derived from a common tissue source or progenitor, vary in their gene expression, and this in turn influences their behavior and fate. It is thus important to analyze transcriptomes at single-cell resolution. In a Review, Azim Surani and colleagues take the reader through the steps of single-cell transcriptome analysis, from the isolation of single cells to the release and reverse transcription of mRNA and the amplification of the resulting cDNA, followed by DNA microarray analysis or high-throughput sequencing. The authors present available software tools for bioinformatic analysis of sequence data and discuss current limitations of single-cell transcriptome analyses such as the lack of discrimination between sense and antisense strands and the exclusion of non-polyadenylated transcripts. Finally, they describe up-and-coming areas such as single-molecule sequencing for full-length RNAs and the ability to sequence RNA that is actively being translated. (Nat. Methods 8, S6–S11, 2011)
Transcript imaging - Validating transcripts in single cells
Schematic of a branched probe for transcript imaging
High-throughput sequencing of transcripts in a single cell yields bulk information on what is being transcribed; to follow up on single transcripts in more detail, one needs to visualize the transcripts. In a Review, Alexander van Oudenaarden and Shalev Itzkovitz discuss methods for single-molecule transcript imaging in living and fixed cells. For transcript imaging in fixed cells, they describe fluorescence in situ hybridization (FISH) and derivative approaches based on labeled probes. For live cells, the authors compare methods based on gene fusion to the MS2 bacteriophage coat protein and molecular beacons. They discuss imaging technology and data analysis needed to extract information from single-molecule FISH experiments. In an outlook section they provide a glimpse into what is still required to make these methods more sensitive and to combine them with quantitative measurements of DNA and protein for a more complete picture of the expression networks that underlie tissue function. (Nat. Methods 8, S12–S19, 2011)

Advanced qPCR Techniques for Publication Success: Following MIQE Recommendation
http://www.embl.de/training/events/2011/MIQ11-01/index.html
Overview -The real-time reverse transcription (RT) polymerase chain reaction (PCR) (RT-qPCR) and real time PCR methods address the evident requirement for quantitative data analysis in molecular medicine, biotechnology, microbiology, diagnostics and other areas and have become the methods of choice for the quantification of nucleic acid targets and identification of sequence specific variations. Although often described as a "gold" standard, these are far from being routine assays.
Date: July 11–15, 2011
