The complexity of this \u0027extracellular matrix\u0027 makes it difficult to identify ligand-receptor interactions with adherent cells and to understand the signaling pathways that these interactions regulate.  This seminar Will describe a bottom-up approach that uses self-assembled monolayers to prepare substrates that are simple mimics of the complex matrix.  Examples will include the use of surfaces that control the shapes, sizes, and differentiation of cells, the use of surfaces to identify novel adhesion ligands in the extracellular matrix and the preparation of surfaces that are dynamic in that the activities of immobilized ligands can be switched on and off while cells are adherent.  These examples reveal the molecular control that is now possible in creating models of the extracellular matrix and illustrate how the tailored substrates can be valuable in fundamental studies of cell adhesion and signaling.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:christine.payne@chemistry.gatech.edu\u0022\u003EProf. Christine Payne\u003C\/a\u003E (404-385-3125).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Milan Mrksich, University of Chicago\n\nTailored Substrates for Cell Biology","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Milan Mrksich, University of Chicago"}],"uid":"27275","created_gmt":"2009-05-06 00:00:00","changed_gmt":"2016-10-08 01:57:11","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2009-09-10T16:00:00-04:00","event_time_end":"2009-09-10T17:00:00-04:00","event_time_end_last":"2009-09-10T17:00:00-04:00","gmt_time_start":"2009-09-10 20:00:00","gmt_time_end":"2009-09-10 21:00:00","gmt_time_end_last":"2009-09-10 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/mrksich-group.uchicago.edu\/mrksich.htm","title":"Prof. Milan Mrksich, University of Chicago"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"5232","name":"paleobiochemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
