    CellH5: a format for data exchange in high-content screening (2013)
    Oxford University Press
    Details
    Publication Date: 2013-06-06
    Description: : High-throughput microscopy data require a diversity of analytical approaches. However, the construction of workflows that use algorithms from different software packages is difficult owing to a lack of interoperability. To overcome this limitation, we present CellH5, an HDF5 data format for cell-based assays in high-throughput microscopy, which stores high-dimensional image data along with inter-object relations in graphs. CellH5Browser, an interactive gallery image browser, demonstrates the versatility and performance of the file format on live imaging data of dividing human cells. CellH5 provides new opportunities for integrated data analysis by multiple software platforms. Availability: Source code is freely available at www.github.com/cellh5 under the GPL license and at www.bioconductor.org/packages/release/bioc/html/rhdf5.html under the Artistic-2.0 license. Demo datasets and the CellH5Browser are available at www.cellh5.org . A Fiji importer for cellh5 will be released soon.

    Phenotypic profiling of the human genome by time-lapse microscopy reveals cell division genes (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-04-03
    Description: Despite our rapidly growing knowledge about the human genome, we do not know all of the genes required for some of the most basic functions of life. To start to fill this gap we developed a high-throughput phenotypic screening platform combining potent gene silencing by RNA interference, time-lapse microscopy and computational image processing. We carried out a genome-wide phenotypic profiling of each of the approximately 21,000 human protein-coding genes by two-day live imaging of fluorescently labelled chromosomes. Phenotypes were scored quantitatively by computational image processing, which allowed us to identify hundreds of human genes involved in diverse biological functions including cell division, migration and survival. As part of the Mitocheck consortium, this study provides an in-depth analysis of cell division phenotypes and makes the entire high-content data set available as a resource to the community.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3108885/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3108885/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Neumann, Beate -- Walter, Thomas -- Heriche, Jean-Karim -- Bulkescher, Jutta -- Erfle, Holger -- Conrad, Christian -- Rogers, Phill -- Poser, Ina -- Held, Michael -- Liebel, Urban -- Cetin, Cihan -- Sieckmann, Frank -- Pau, Gregoire -- Kabbe, Rolf -- Wunsche, Annelie -- Satagopam, Venkata -- Schmitz, Michael H A -- Chapuis, Catherine -- Gerlich, Daniel W -- Schneider, Reinhard -- Eils, Roland -- Huber, Wolfgang -- Peters, Jan-Michael -- Hyman, Anthony A -- Durbin, Richard -- Pepperkok, Rainer -- Ellenberg, Jan -- 077192/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Apr 1;464(7289):721-7. doi: 10.1038/nature08869.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MitoCheck Project Group, European Molecular Biology Laboratory (EMBL), Meyerhofstrasse 1, D-69117 Heidelberg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360735" target="_blank"〉PubMed〈/a〉

    Cortical constriction during abscission involves helices of ESCRT-III-dependent filaments (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-02-12
    Description: After partitioning of cytoplasmic contents by cleavage furrow ingression, animal cells remain connected by an intercellular bridge, which subsequently splits by abscission. Here, we examined intermediate stages of abscission in human cells by using live imaging, three-dimensional structured illumination microscopy, and electron tomography. We identified helices of 17-nanometer-diameter filaments, which narrowed the cortex of the intercellular bridge to a single stalk. The endosomal sorting complex required for transport (ESCRT)-III co-localized with constriction zones and was required for assembly of 17-nanometer-diameter filaments. Simultaneous spastin-mediated removal of underlying microtubules enabled full constriction at the abscission site. The identification of contractile filament helices at the intercellular bridge has broad implications for the understanding of cell division and of ESCRT-III-mediated fission of large membrane structures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guizetti, Julien -- Schermelleh, Lothar -- Mantler, Jana -- Maar, Sandra -- Poser, Ina -- Leonhardt, Heinrich -- Muller-Reichert, Thomas -- Gerlich, Daniel W -- New York, N.Y. -- Science. 2011 Mar 25;331(6024):1616-20. doi: 10.1126/science.1201847.
