From user-defined reactions and initial substance quantities, it generates cell lineages, i.e. genealogic pedigrees of cells related through mitotic division. Each cell's dynamics is driven by a delayed stochastic simulation algorithm (delayed SSA), allowing multiple time delayed reactions.<\/jats:p><jats:p>The cells of the lineage can be individually subject to \u2018perturbations\u2019, such as gene deletion, duplication and mutation. External interventions, such as adding or removing a substance at a given moment, can be specified. Cell differentiation lineages, where differentiation is stochastically driven or externally induced, can be modeled as well. Finally, CellLine can generate and simulate the dynamics of multiple copies of any given cell of the lineage.<\/jats:p><jats:p>As examples of CellLine use, we simulate the following systems: cell lineages containing a model of the P53-Mdm2 feedback loop, a differentiation lineage where each cell contains a 4 gene repressilator (a bistable circuit), a model of the differentiation of the cells of the retinal mosaic required for color vision in Drosophila melanogaster, where the differentiation pathway depends on one substance's concentration that is controlled by a stochastic process, and a 9 gene GRN to illustrate the advantage of using CellLine rather than simulating multiple independent cells, in cases where the cells of the lineage are dynamically correlated.<\/jats:p><jats:p>Availability: The CellLine program, instructions and examples are available at http:\/\/www.cs.tut.fi\/~sanchesr\/CellLine\/CellLine.html<\/jats:p><jats:p>Contact: \u00a0andre.sanchesribeiro@tut.fi<\/jats:p>","DOI":"10.1093\/bioinformatics\/btm491","type":"journal-article","created":{"date-parts":[[2007,10,11]],"date-time":"2007-10-11T00:13:23Z","timestamp":1192061603000},"page":"3409-3411","source":"Crossref","is-referenced-by-count":8,"title":["<i>CellLine<\/i>, a stochastic cell lineage simulator"],"prefix":"10.1093","volume":"23","author":[{"given":"Andre S.","family":"Ribeiro","sequence":"first","affiliation":[{"name":"Institute for Biocomplexity and Informatics, University of Calgary, Canada"}]},{"given":"Daniel A.","family":"Charlebois","sequence":"additional","affiliation":[{"name":"Institute for Biocomplexity and Informatics, University of Calgary, Canada"}]},{"given":"Jason","family":"Lloyd-Price","sequence":"additional","affiliation":[{"name":"Institute for Biocomplexity and Informatics, University of Calgary, Canada"}]}],"member":"286","published-online":{"date-parts":[[2007,10,9]]},"reference":[{"key":"2023041107444012600_","doi-asserted-by":"crossref","first-page":"1129","DOI":"10.1126\/science.1070919","article-title":"Stochastic gene expression in a single cell","volume":"297","author":"Elowitz","year":"2002","journal-title":"Science"},{"key":"2023041107444012600_","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1007\/s11538-006-9066-z","article-title":"Gene expression time delays and turing pattern formation systems","volume":"68","author":"Gaffney","year":"2006","journal-title":"Bull.
