Knowledge of differentiation network will enable generation of desired cell fates by careful alteration of the governing network by adequate manipulation of cellular environment.<\/jats:p>\n               <jats:p>Results: We have developed a novel integer programming-based approach to reconstruct the underlying regulatory architecture of differentiating embryonic stem cells from discrete temporal gene expression data. The network reconstruction problem is formulated using inherent features of biological networks: (i) that of cascade architecture which enables treatment of the entire complex network as a set of interconnected modules and (ii) that of sparsity of interconnection between the transcription factors. The developed framework is applied to the system of embryonic stem cells differentiating towards pancreatic lineage. Experimentally determined expression profile dynamics of relevant transcription factors serve as the input to the network identification algorithm. The developed formulation accurately captures many of the known regulatory modes involved in pancreatic differentiation. The predictive capacity of the model is tested by simulating an in silico potential pathway of subsequent differentiation. The predicted pathway is experimentally verified by concurrent differentiation experiments. Experimental results agree well with model predictions, thereby illustrating the predictive accuracy of the proposed algorithm.<\/jats:p>\n               <jats:p>Contact: \u00a0ipb1@pitt.edu<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btq139","type":"journal-article","created":{"date-parts":[[2010,4,2]],"date-time":"2010-04-02T00:13:12Z","timestamp":1270167192000},"page":"1332-1339","source":"Crossref","is-referenced-by-count":7,"title":["An integer programming formulation to identify the sparse network architecture governing differentiation of embryonic stem cells"],"prefix":"10.1093","volume":"26","author":[{"given":"Ipsita","family":"Banerjee","sequence":"first","affiliation":[{"name":"1 Center for Engineering in Medicine, Massachusetts General Hospital, Harvard Medical School, Shriners Hospital for Children, 51 Blossom Street, Boston, MA-02114, 2 Department of Chemical Engineering, University of Pittsburgh, 1242 Benedum Hall, 3700 O'Hara Street, Pittsburgh, PA 15261 and3 Department of Mechanical Engineering \u2013 Engineering Mechanics, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA"},{"name":"1 Center for Engineering in Medicine, Massachusetts General Hospital, Harvard Medical School, Shriners Hospital for Children, 51 Blossom Street, Boston, MA-02114, 2 Department of Chemical Engineering, University of Pittsburgh, 1242 Benedum Hall, 3700 O'Hara Street, Pittsburgh, PA 15261 and3 Department of Mechanical Engineering \u2013 Engineering Mechanics, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Spandan","family":"Maiti","sequence":"additional","affiliation":[{"name":"1 Center for Engineering in Medicine, Massachusetts General Hospital, Harvard Medical School, Shriners Hospital for Children, 51 Blossom Street, Boston, MA-02114, 2 Department of Chemical Engineering, University of Pittsburgh, 1242 Benedum Hall, 3700 O'Hara Street, Pittsburgh, PA 15261 and3 Department of Mechanical Engineering \u2013 Engineering Mechanics, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natesh","family":"Parashurama","sequence":"additional","affiliation":[{"name":"1 Center for Engineering in Medicine, Massachusetts General Hospital, Harvard Medical School, Shriners Hospital for Children, 51 Blossom Street, Boston, MA-02114, 2 Department of Chemical Engineering, University of Pittsburgh, 1242 Benedum Hall, 3700 O'Hara Street, Pittsburgh, PA 15261 and3 Department of Mechanical Engineering \u2013 Engineering Mechanics, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Yarmush","sequence":"additional","affiliation":[{"name":"1 Center for Engineering in Medicine, Massachusetts General Hospital, Harvard Medical School, Shriners Hospital for Children, 51 Blossom Street, Boston, MA-02114, 2 Department of Chemical Engineering, University of Pittsburgh, 1242 Benedum Hall, 3700 O'Hara Street, Pittsburgh, PA 15261 and3 Department of Mechanical Engineering \u2013 Engineering Mechanics, Michigan Technological University, 1400 Townsend Drive, Houghton, MI 49931, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2010,3,31]]},"reference":[{"key":"2023012507520828400_B1","doi-asserted-by":"crossref","first-page":"815","DOI":"10.1093\/bioinformatics\/btl003","article-title":"Inference of gene regulatory networks and compound mode of action from time course gene expression profiles","volume":"22","author":"Bansal","year":"2006","journal-title":"Bioinformatics"},{"key":"2023012507520828400_B2","doi-asserted-by":"crossref","first-page":"17533","DOI":"10.1074\/jbc.M009088200","article-title":"A pancreatic \u03b2-cell-specific enhancer in the human Pdx-1 gene is regulated by HNF-3\u03b2, HNF\u22121\u03b1, and SPs transcription factors","volume":"276","author":"Ben-Shushan","year":"2001","journal-title":"J.
