The automated reconstruction of a prototypic 4D atlas for vertebrate early embryos, using multicolor fluorescence <i>in situ</i> hybridization with nuclear counterstain, requires dedicated computational strategies. To this goal, we designed an original methodological framework implemented in a software tool called Match-IT. With only minimal human supervision, our system is able to gather gene expression patterns observed in different <i>analyzed embryos</i> with phenotypic variability and map them onto a series of common 3D <i>templates</i> over time, creating a 4D atlas. This framework was used to construct an atlas composed of 6 gene expression templates from a cohort of zebrafish early embryos spanning 6 developmental stages from 4 to 6.3 hpf (hours post fertilization). They included 53 specimens, 181,415 detected cell nuclei and the segmentation of 98 gene expression patterns observed in 3D for 9 different genes. In addition, an interactive visualization software, Atlas-IT, was developed to inspect, supervise and analyze the atlas. Match-IT and Atlas-IT, including user manuals, representative datasets and video tutorials, are publicly and freely available online. We also propose computational methods and tools for the quantitative assessment of the gene expression templates at the cellular scale, with the identification, visualization and analysis of coexpression patterns, synexpression groups and their dynamics through developmental stages.</p></div>", "links"=>[], "tags"=>["Computational biology", "developmental biology", "morphogenesis", "molecular biology", "Molecular biology techniques", "Gene mapping", "organisms", "animals", "vertebrates", "fishes", "osteichthyes", "zebrafish", "signal processing", "Image processing", "visualize", "atlas", "cellular"], "article_id"=>1062262, "categories"=>["Biological Sciences"], "users"=>["Carlos Castro-González", "Miguel A.
