Immune Cells Composition of Humanized Mouse Kidney Compared to Normal Human Kidney
*Purpose: Most clinical studies fail in spite of promising mouse studies, in part due to fundamental differences between mice and human responses. Attempts have been…2019 American Transplant Congress
Pluripotent Stem Cell Differentiation: Delaying Forward Differentiation Signals Maintains Definitive Endoderm Phenotype for Cellular Transplantation
*Purpose: Endodermal precursors (EP), derived in vitro from mouse pluripotent stem cell (PSC) sources, are capable of clinically useful engraftment in the unmodified (quiescent) liver…2019 American Transplant Congress
CD46 Transgene Modification and Thrombosis in Neonatal Porcine Islet Xenotransplantation
Surgery, Duke University, Durham, NC
*Purpose: Vascular thrombosis activation is an important cause for early xeno-islet loss. To better understand the thrombosis process in islet xenotransplantation and the effect of…2019 American Transplant Congress
Differentiation and Characterization of Human Endodermal Precursors for Liver Cell Therapies
*Purpose: Mouse pluripotent stem cell (PSC)-derived endoderm precursors (EPs) have small size, endoderm lineage gene expression signatures, and high proliferation rates, that allow engraftment in…2019 American Transplant Congress
AMD3100 (Plerixafor) as a Single-Dose Stem Cell Mobilizing Agent in Vascularized Composite Tissue Allograft (VCA) Transplantation in a Canine DLA-Mismatch Model
*Purpose: Vascularized Composite Allograft (VCA) transplantation is a clinical reality but limited by toxicities of chronic immunosuppression and rejection. Current clinical tolerance protocols rely on…2019 American Transplant Congress
Parathyroid CD34+ Cells Induce Neovascularization of Donor and Recipient Leading to Chimeric Vessel Formation and Improved Engraftment of Co-Transplanted Pancreatic Islets
1UCSF, San Francisco, CA, 2San Francisco Veterans Affairs, San Francisco, CA
*Purpose: We recently showed improved engraftment and diabetes reversal when mature islets or stem-cell-derived beta cells (SCIPC) were co-transplanted with parathyroid gland (PTG). The CD34+…2019 American Transplant Congress
Can Cxcl8 Inhibitor (reparixin) Improve Islet Engraftment And Clinical Outcomes After Islet Allotransplantation? University Of Chicago Preliminary Results From A Phase 3 Multicenter Randomized, Double-blinded, Prospective Study.
1University of Chicago Medicine, Chicago, IL, 2Medical University of Gdansk, Gdansk, Poland
*Purpose: Reparixin is a novel CxCR1/2 chemokine receptor-blocking molecule, which has been shown improving islet engraftment in animal models. A multicenter trial was organized to…2018 American Transplant Congress
The Role of CD46 in Early Islet Engraftment in a Dual Transplant Model
Department of Surgery, Duke University School of Medicine, Durham, NC.
IntroductionMembrane cofactor protein (CD46) is known to attenuate the complement cascade by facilitating cleavage of C3b and C4b. In solid organ xenotransplantation, organs expressing CD46…2018 American Transplant Congress
Robust Hematopoietic Mixed Chimerism and Donor-Specific Skin Allograft Tolerance after Non-Genotoxic Anti-CD117 Immunotoxin Conditioning and Donor Bone Marrow Allotransplantation
Establishing hematopoietic chimerism enables donor-specific allograft tolerance; however, chimerism protocols typically require either genotoxic conditioning or mega-doses of donor bone marrow cells (BMC), impeding clinical…2018 American Transplant Congress
A Novel Approach to Preserve Pancreatic Islet Grafts in Extrahepatic Space for Reversal of Diabetes Using Parathyroid Gland Co-Transplantation
Intro: Islet transplantation can cure type 1 diabetes; however, multiple donors are needed due to extensive perioperative loss of islets away from their native blood…
