Cell response (from both therapeutic cells and host tissue) is dependent on multiple properties (chemistry, mechanical property and topology) of scaffolds. To achieve improved \u003Cem\u003Ein vivo\u003C\/em\u003E performance, optimization on multiple properties of scaffolds are desired. However, traditional scaffolds are often composed of single material with distinct merits as well as drawbacks and usually display bulk topology, lacking regulation of cells on multiple scales.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this project, three types of scaffolds with integrated properties were developed and characterized. In the first study, nano-thin hydrogel was integrated on surface of polyester microfiber. After integration, the scaffold became water absorbable meanwhile preserving the mechanical strength of microfibers. In the second study, scaffolds with multiple scales of topologies was achieved by introducing microwell patterns on electrospun fibers. We found the microwell patterns could regulate the spatial distribution of seeded mesenchymal stem cell (MSC) spheroids. We further tested their application in MSC transplantation in mice model of hind limb ischemia. In the third study, spherical hollow scaffolds with controllable pore size were developed. The scaffold showed unique parallel channels bearing nanoscale to microscale pores. When loaded with MSCs, the cells showed\u003Cem\u003E in vitro\u003C\/em\u003E cellular responses and \u003Cem\u003Ein vivo\u003C\/em\u003E residence time that were correlatable with the pore structures within the bead wall. Overall, this work adds to our knowledge of strategies for development of scaffold with integrated properties, and broadens our understanding of design principles of scaffolds to be used for cell transplantation.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETo join the Meeting:\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022https:\/\/bluejeans.com\/681178207\u0022\u003Ehttps:\/\/bluejeans.com\/681178207\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETo join via phone :\u003C\/p\u003E\r\n\r\n\u003Cp\u003E1)\u0026nbsp; Dial:\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u003Cspan class=\u0022baec5a81-e4d6-4674-97f3-e9220f0136c1\u0022 style=\u0022white-space:nowrap\u0022\u003E+1.408.740.7256\u003C\/span\u003E (United States)\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u003Cspan class=\u0022baec5a81-e4d6-4674-97f3-e9220f0136c1\u0022 style=\u0022white-space:nowrap\u0022\u003E+1.888.240.2560\u003C\/span\u003E (US Toll Free)\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u003Cspan class=\u0022baec5a81-e4d6-4674-97f3-e9220f0136c1\u0022 style=\u0022white-space:nowrap\u0022\u003E+1.408.317.9253\u003C\/span\u003E (Alternate number)\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp; (see all numbers - \u003Ca href=\u0022http:\/\/bluejeans.com\/numbers\u0022\u003Ehttp:\/\/bluejeans.com\/numbers\u003C\/a\u003E)\u003C\/p\u003E\r\n\r\n\u003Cp\u003E2)\u0026nbsp; Enter Conference ID : 681178207\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Scaffold with integrated properties and applications in cell transplantation"}],"uid":"27707","created_gmt":"2017-06-07 12:20:44","changed_gmt":"2017-06-07 12:20:44","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-06-07T21:15:00-04:00","event_time_end":"2017-06-07T23:00:00-04:00","event_time_end_last":"2017-06-07T23:00:00-04:00","gmt_time_start":"2017-06-08 01:15:00","gmt_time_end":"2017-06-08 03:00:00","gmt_time_end_last":"2017-06-08 03:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
