Analysis

Extracting a cellular hierarchy from high-dimensional cytometry data with SPADE pp886 - 891

Peng Qiu, Erin F Simonds, Sean C Bendall, Kenneth D Gibbs Jr, Robert V Bruggner, Michael D Linderman, Karen Sachs, Garry P Nolan & Sylvia K Plevritis

doi:10.1038/nbt.1991

New instruments can measure the presence of >30 molecular markers for massive numbers of single cells, but data analysis algorithms have lagged behind. Qiu et al. describe an approach called SPADE for recovering cellular hierarchies from mass or flow cytometry data.

Direct lineage conversions: unnatural but useful? pp892 - 907

Thomas Vierbuchen & Marius Wernig

doi:10.1038/nbt.1946


Analysis

Performance comparison of exome DNA sequencing technologies pp908 - 914

Michael J Clark, Rui Chen, Hugo Y K Lam, Konrad J Karczewski, Rong Chen, Ghia Euskirchen, Atul J Butte & Michael Snyder

doi:10.1038/nbt.1975

Capturing and sequencing only the coding regions of the human genome leverages resources in the pursuit of rare disease-causing mutations. Clark et al. compare the performance of three leading exome-capture methods and their advantages over whole-genome sequencing.

Efficient de novo assembly of single-cell bacterial genomes from short-read data sets pp915 - 921

Hamidreza Chitsaz, Joyclyn L Yee-Greenbaum, Glenn Tesler, Mary-Jane Lombardo, Christopher L Dupont, Jonathan H Badger, Mark Novotny, Douglas B Rusch, Louise J Fraser, Niall A Gormley, Ole Schulz-Trieglaff, Geoffrey P Smith, Dirk J Evers, Pavel A Pevzner & Roger S Lasken

doi:10.1038/nbt.1966

DNA can be amplified and sequenced from a single cell, but unevenness of the sequence coverage complicates efforts to assemble a high-quality genome. Chitsaz et al. devise an algorithm to address this problem and apply it to assemble a genome draft of an uncultured single-cell marine organism from one lane of Illumina sequence data.


Comparative genomic analysis of the thermophilic biomass-degrading fungi Myceliophthora thermophila and Thielavia terrestris pp922 - 927

Randy M Berka, Igor V Grigoriev, Robert Otillar, Asaf Salamov, Jane Grimwood, Ian Reid, Nadeeza Ishmael, Tricia John, Corinne Darmond, Marie-Claude Moisan, Bernard Henrissat, Pedro M Coutinho, Vincent Lombard, Donald O Natvig, Erika Lindquist, Jeremy Schmutz, Susan Lucas, Paul Harris, Justin Powlowski, Annie Bellemare, David Taylor, Gregory Butler, Ronald P de Vries, Iris E Allijn, Joost van den Brink, Sophia Ushinsky, Reginald Storms, Amy J Powell, Ian T Paulsen, Liam D H Elbourne, Scott E Baker, Jon Magnuson, Sylvie LaBoissiere, A John Clutterbuck, Diego Martinez, Mark Wogulis, Alfredo Lopez de Leon, Michael W Rey & Adrian Tsang

doi:10.1038/nbt.1976

Thermostable enzymes are used for a range of industrial processes, including biofuel production. Berka et al. report the genome sequences of two thermophilic eukaryotic fungi with enzymes that operate at the elevated temperatures needed to digest biomass and prepare many biochemicals.


Tracking single hematopoietic stem cells in vivo using high-throughput sequencing in conjunction with viral genetic barcoding pp928 - 933

Rong Lu, Norma F Neff, Stephen R Quake & Irving L Weissman

doi:10.1038/nbt.1977

Heterogeneity within populations of stem cells, cancer cells or other cell types of interest presents a formidable barrier to analysis. Lu et al. use viral barcoding and high-throughput sequencing to track the differentiation of single hematopoietic stem cells in vivo.


CD140a identifies a population of highly myelinogenic, migration-competent and efficiently engrafting human oligodendrocyte progenitor cells pp934 - 941

Fraser J Sim, Crystal R McClain, Steven J Schanz, Tricia L Protack, Martha S Windrem & Steven A Goldman

doi:10.1038/nbt.1972

Oligodendrocyte progenitors capable of myelination in myelin-deficient mice have been isolated from human fetal brain cells, but at low purity. Sim et al. show that sorting based on PDGFRα expression yields a purer population of myelinogenic cells free of neuronal and committed astrocyte cells.

A reversibly photoswitchable GFP-like protein with fluorescence excitation decoupled from switching pp942 - 947

Tanja Brakemann, Andre C Stiel, Gert Weber, Martin Andresen, Ilaria Testa, Tim Grotjohann, Marcel Leutenegger, Uwe Plessmann, Henning Urlaub, Christian Eggeling, Markus C Wahl, Stefan W Hell & Stefan Jakobs

doi:10.1038/nbt.1952

Brakemann et al. present a reversibly photoswitchable fluorescent protein, called Dreiklang, that can be turned on and off at wavelengths distinct from those used for imaging. They show that the protein is advantageous for studying protein dynamics in living cells and for super-resolution imaging.
