Neonatal Tolerance Induction: Behaviours of Allogeneic Spleen and Bone Marrow Inocula in Neonatal Mice are Largely Determined by the Nature of Their CD8 T Cells
R. A. Bascom, K. Tao, L. J. West
University of Alberta, Edmonton, AB, Canada
*Purpose: Injected adult allo-spleen (SC) and bone marrow cells (BMC) traffic to secondary lymphoid organs, proliferate and spread throughout neonatal mice; allo-SC consistently cause acute…

Steatosis by PDFF Affects Percent Remnant Liver Regeneration in Living Donors without Impacting on Clinical Outcomes
A. Duarte-Rojo, Q. Qi, K. Chupetlovska, D. R. Jorgensen, A. A. Borhani, A. Furlan, S. Ganesh, A. Humar
University of Pittsburgh Medical Center, Pittsburgh, PA
*Purpose: Mild steatosis (5-33% of fat) is not expected to affect liver regeneration following partial hepatectomy. Novel methods to assess steatosis, such as proton density…

Impact of Kidney Transplant Type and Previous Transplant on Baseline Donor-Derived Cell Free DNA
K. K. Sureshkumar, B. Chopra
Nephrology and Hypertension, Allegheny General Hospital, Pittsburgh, PA
*Purpose: Donor derived-cell free DNA (dd-cfDNA) is a biomarker useful in predicting acute rejection in renal allografts. The technology uses next generation sequencing and does…

Photo Elicitation Interviewing Exposes Educational Discordance Amidst a Web of Resources among Kidney Transplant Recipients
J. R. Montgomery, M. J. Kirsch, A. Rau, M. E. Byrnes, S. A. Waits
General Surgery, University of Michigan, Ann Arbor, MI
*Purpose: Comprehensive patient education is the bedrock of success for kidney transplant (KT) recipients. Despite the importance, we have a poor understanding of how patients…

R. A. Bascom, K. Tao, L. J. West
Pediatrics, University of Alberta, Edmonton, AB, Canada
*Purpose: Comparing the behaviour of fully allogeneic spleen (SC) vs bone marrow cells (BMC) in non-conditioned neonatal mice is important for maximizing synergistic interactions between…
