However, limitations of this treatment approach, including limited tissue availability and poor revascularization post-grafting, have motivated the development of cell- and protein-based strategies. Although recombinant human bone morphogenetic protein 2 (rhBMP-2) is clinically utilized to promote bone repair in incidences of non-union, supra-physiologic dosing of rhBMP-2 can result in adverse effects including heterotopic bone formation and systemic inflammation. Mesenchymal stem cell (MSC)-based bone tissue engineering strategies offer several potential advantages over the use of osteoinductive protein alone. However, challenges to control delivered cell behavior remain a significant barrier to the clinical translation of MSC-based therapeutics.\u003C\/p\u003E\u003Cp\u003EHuman platelet lysate (hPL) utilization and cell aggregation have each demonstrated the capacity to modulate a range of MSC outcomes, including cell number, phenotype, and secretome. The goal of this work was to investigate their potential application in MSC-based large bone defect repair. We pursued this objective through development of a bioluminescent cell tracking protocol and subsequent evaluation of these strategies for improved MSC survival and facilitated bone regeneration. Additional to engineering an efficacious MSC-based treatment for bone injury, this research aimed to relate key principles influencing cell-based tissue regeneration more globally.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EPhD Defense Presentation-\u0026nbsp;\u0022Modulation of Stem Cell Delivery Strategy by Platelet Lysate Utilization and Cell Aggregation for Enhanced Bone Regeneration\u0022- Ashley Allen\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"\u0022Modulation of Stem Cell Delivery Strategy by Platelet Lysate Utilization and Cell Aggregation for Enhanced Bone Regeneration\u0022"}],"uid":"27917","created_gmt":"2015-06-09 11:18:49","changed_gmt":"2017-04-13 21:19:13","author":"Laura Paige","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-06-24T10:00:00-04:00","event_time_end":"2015-06-24T12:00:00-04:00","event_time_end_last":"2015-06-24T12:00:00-04:00","gmt_time_start":"2015-06-24 14:00:00","gmt_time_end":"2015-06-24 16:00:00","gmt_time_end_last":"2015-06-24 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/guldberglab.gatech.edu\/","title":"Guldberg Musculoskeletal Research Lab"}],"groups":[{"id":"65448","name":"Bioengineering Graduate Program"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003ELaura Paige\u003C\/p\u003E\u003Cp\u003E404-385-6655\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
