AMD3100 (Plerixafor) as a Single-Dose Stem Cell Mobilizing Agent in Vascularized Composite Tissue Allograft (VCA) Transplantation in a Canine DLA-Mismatch Model
B. Swearingen¹, S. Graves², R. Storb², D. W. Mathes¹
¹University of Colorado School of Medicine, Aurora, CO, ²Fred Hutchinson Cancer Research Center, Seattle, WA
*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…

Pharmacological Mobilization of Host Stem Cells Prevents Delayed Graft Function Following Kidney Transplantation in Rats
W. Wang, L. Qi, J. Huang, A. Ahmadi, A. Krishnan, R. Wesson, A. Cameron, Z. Sun
Johns Hopkins University School of Medicine, Baltimore, MD
*Purpose: Delayed graft function (DGF) caused by ischemia-reperfusion injury (IRI) is an early complication that occurs in nearly a quarter of all deceased-donor kidneys and…

Human Mesenchymal Stem Cells Inhibits Hypoxia-Induced Islets Apoptosis via Regulation of Autophagy
R. Pengfei, X. Yuzhi
The Third Xiang Ya Hospital,Central South University, ChangSha, China
*Purpose: Xenotransplantation of porcine islets has been an emerging and effective option for clinicians to treat type 1 diabetes recently. Comparing with other damage, hypoxic…

Human Neutrophil Function against Pathogens in Solid Organ and Stem Cell Transplant Recipients
N. Barros, N. Alexander, Z. Dagher, S. Knooihuizen, A. Viens, A. R. Hopke, D. Irimia, M. K. Mansour
Transplant Infectious Diseases, Massachusetts General Hospital, Boston, MA
*Purpose: The effects of solid organ (SOT) and allogeneic stem cell transplantation (SCT) on the neutrophil function is not well described. In this study, we…

Immune Cells Composition of Humanized Mouse Kidney Compared to Normal Human Kidney
S. Noel¹, J. T. Kurzhagen¹, S. Lee¹, M. Sadasivam², A. R. Hamad², P. M. Pierorazio³, H. Rabb¹
¹Medicine, Johns Hopkins University, Baltimore, MD, ²Pathology, Johns Hopkins University, Baltimore, MD, ³Urology, Johns Hopkins University, Baltimore, MD
*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…

RNA Splicing and Lineage Progression: Identification of an Integrated Splicing Pattern in Endodermal Lineage Progression
J. Fair¹, N. Liu¹, S. G. Widen², W. S. Fagg¹
¹Surgery, University of Texas Medical Branch, Galveston, TX, ²Biochemistry and Molecular Biology, University of Texas Medical Branch, Galveston, TX
*Purpose: Epigenetic states such as histone modifications and DNA methylation that influence transcription are well-characterized regulators of stem cell pluripotency and differentiation to specific lineages.…

Pluripotent Stem Cell Differentiation: Delaying Forward Differentiation Signals Maintains Definitive Endoderm Phenotype for Cellular Transplantation
J. Fair¹, M. M. Shoja¹, N. Liu¹, I. Patrikeev², M. Motamedi², W. S. Fagg¹
¹Surgery, University of Texas Medical Branch, Galveston, TX, ²Opthalmology and Visual Sciences, University of Texas Medical Branch, Galveston, TX
*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…

An Open-Label Proof-of-Principle Phase 2A Study to Evaluate Autologous Hematopoietic Stem Cell Transplantation for Allogeneic Organ Transplant Tolerance (ASCOTT)
A. Chruscinski¹, H. Atkins², A. Clement², D. Grant¹, C. Bredsen², E. Renner¹, J. Zhang¹, M. Epstein¹, L. Lilly¹, N. Selzner¹, O. Adeyi¹, R. Smith¹, S. Moshkelgosha¹, A. Humar¹, S. Juvet¹, G. Levy¹
¹Multi-Organ Transplantation, University Health Network, Toronto, ON, Canada, ²Ottawa Hospital Research Institute, Ottawa, ON, Canada
*Purpose: Long-term survival of recipients of solid organ transplants is hampered by chronic rejection, disease recurrence and immunosuppression-induced toxicity. Self-tolerance is re-established after autologous hematopoietic…
