SUMMARY:BE Seminar: "Engineering Synthetic Biomaterials for Islet Transplantation" (María M. Coronel)
DESCRIPTION:This event will be held virtually via Zoom (check email or contact ksas@seas.upenn.edu). \nTwo major challenges to the translation of cellular-based tissue-engineered therapies are the lack of adequate oxygen support post-implantation and the need for systemic immunosuppression to halt the strong inflammatory and immunological response of the host. As such\, strategies that aim at addressing oxygen demand\, and local immunological responses can be highly beneficial in the translation of these therapies. In this seminar\, I will focus on two biomaterial strategies to create a more favorable transplant niche for pancreatic islet transplantation. The first half will describe an in-situ oxygen-releasing biomaterial fabricated through the incorporation of solid peroxides in a silicone polymer. The implementation of this localized\, controlled and sustained oxygen-generator mitigates the activation of detrimental hypoxia-induced pathways in islets and enhances the potency of extrahepatic 3D islet-loaded devices in a diabetic animal model. In the second part\, I will focus on engineering synthetic biomaterials for the delivery of immunomodulatory signals for transplant acceptance. Biomaterial carriers fabricated with polyethylene glycol microgels are used to deliver immunomodulatory signals to regulate the local microenvironment and prevent allograft rejection in a clinically relevant pre-clinical transplant model. The use of synthetic materials as an off-the-shelf platform\, without the need for manipulating the biological cell product\, improves the clinical translatability of this engineered approach. Designing safer\, responsive biomaterials to boost the delivery of targeted therapeutics will significantly reinvigorate interventional cell-based tissue-engineered therapies.
