However, these possibilities are hampered by challenges in controlling transplanted cell fate, and the limited prognostic capabilities of overly simplistic in vitro models.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nI will describe the use of biomaterials and bioengineering approaches to overcome both sets of challenges. I will first describe studies on control of MSC differentiation via 3D hydrogel rigidity, the use of new biochemical and molecular fluorescence (FRET) assays to discover morphology-independent mechanisms for that MSC mechanosensing, and finally, the application of this knowledge to control osteogenic behavior of transplanted MSC. I will next describe the development of miniaturized Heart-On-A-Chip models from genetically defined Human Induced Pluripotent Stem Cells (iPS). Culturing iPS-derived cardiomyocytes (iPS-CM) in micro-tissues improves maturation into adult-like cardiomyocytes, leading to more clinically relevant physiology and pharmacology. In particular, iPS-CM in micro-tissues exhibit action potentials reminiscent of adult ventricular myocytes, which will likely improve their safety and efficacy in therapeutic transplantation, and increase their utility in drug efficacy and toxicology testing.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nFinally, I will discuss future plans to combine hydrogel and organ-on-a-chip technologies to study mechanisms of mechanically and metabolically linked iPS-CM maturation, as well as to create in vitro models of familial heart disease and the development of other mechanosensitive tissues, including bone. I will also address the application of these mechanistic studies towards the design of new hydrogel materials to control the biology of iPSC and iPS-CM in the context of cell transplantation and cell manufacturing.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nHost: \u003Ca href=\u0022mailto:edward.botchwey@bme.gatech.edu\u0022\u003EEdward Botchwey, Ph.D.\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cbr \/\u003E\r\n\u003Cstrong\u003ETuesday, February 14\u003C\/strong\u003E\u003Cbr \/\u003E\r\n10:30 a.m.\u003Cbr \/\u003E\r\nMcIntire Room 3115,\u003Cbr \/\u003E\r\nWhitaker Bldg.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nVideoconference:\u003Cbr \/\u003E\r\nEmory: HSRB E182\u003Cbr \/\u003E\r\nGeorgia Tech:\u0026nbsp;TEP 104\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"BME Speaker Seminar with Nathaniel Huebsch, Ph.D.*"}],"uid":"27513","created_gmt":"2017-02-06 21:00:27","changed_gmt":"2017-04-13 21:12:57","author":"Walter Rich","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-02-14T10:30:00-05:00","event_time_end":"2017-02-14T11:30:00-05:00","event_time_end_last":"2017-02-14T11:30:00-05:00","gmt_time_start":"2017-02-14 15:30:00","gmt_time_end":"2017-02-14 16:30:00","gmt_time_end_last":"2017-02-14 16:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"586996":{"id":"586996","type":"image","title":"Nathaniel Huebsch, Ph.D.*","body":null,"created":"1486414475","gmt_created":"2017-02-06 20:54:35","changed":"1486414475","gmt_changed":"2017-02-06 20:54:35","alt":"Nathaniel Huebsch, Ph.D.*","file":{"fid":"223695","name":"photo of Nate Huebsch-edited.jpg","image_path":"\/sites\/default\/files\/images\/photo%20of%20Nate%20Huebsch-edited.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/photo%20of%20Nate%20Huebsch-edited.jpg","mime":"image\/jpeg","size":65503,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/photo%20of%20Nate%20Huebsch-edited.jpg?itok=Wbi7QUlA"}}},"media_ids":["586996"],"groups":[{"id":"1254","name":"Wallace H.
