In zebrafish, silberblick (slb)/wnt11 regulates normal gastrulation movements by activating a signalling pathway similar to the Frizzled-signalling pathway, which establishes epithelial planar cell polarity (PCP) in Drosophila. However, the cellular mechanisms by which slb/wnt11 functions during zebrafish gastrulation are still unclear. Using high-resolution two-photon confocal imaging followed by computer-assisted reconstruction and motion analysis, we have analysed the movement and morphology of individual cells in three dimensions during the course of gastrulation. We show that in slb-mutant embryos, hypoblast cells within the forming germ ring have slower, less directed migratory movements at the onset of gastrulation. These aberrant cell movements are accompanied by defects in the orientation of cellular processes along the individual movement directions of these cells. We conclude that slb/wnt11-mediated orientation of cellular processes plays a role in facilitating and stabilising movements of hypoblast cells in the germ ring, thereby pointing at a novel function of the slb/wnt11 signalling pathway for the regulation of migratory cell movements at early stages of gastrulation."}],"pmid":1,"oa":1,"publist_id":"1975","type":"journal_article","publisher":"Company of Biologists","article_type":"original","day":"15","issue":"22","page":"5375 - 5384","intvolume":"       130","language":[{"iso":"eng"}],"date_created":"2018-12-11T12:07:13Z","publication_identifier":{"issn":["1011-6370"]},"title":"Slb/Wnt11 controls hypoblast cell migration and morphogenesis at the onset of zebrafish gastrulation","article_processing_charge":"No","acknowledgement":"We thank Jennifer Geiger, Mathias Köppen, Christian Dahmann and Marcos Gonzalez-Gaitan for helpful comments on earlier versions of this manuscript,Beate Kilian for technical assistance, Ugur Yalcin, Katrin Anczok and Viktor Schnabel for help with the image analysis, Vinzenz Link for programming Excel Macros and Harald Brush-Janovjak for extensive reviews of the statistics part of this work.
