Vimentin Regulates ß-Catenin Translocation During Epithelial to Mesenchymal Transition in Renal Fibrosis.
R. Lopez-Soler, Z. Wang, A. Divanyan.
Sugery, Section of Transplantation, Albany Medical Center, Albany, NY
Introduction: Most renal transplants ultimately fail secondary to chronic allograft nephropathy (CAN). The development of Epithelial to Mesenchymal Transition (EMT) in renal tubular epithelial cells…

Digital Image Analysis of Pediatric Liver Allograft Biopsies Correlates with METAVIR Fibrosis Score.
R. Fischer,¹ S. Foster,² J. Daniel,¹ R. Hendrickson,¹ W. Andrews,¹ A. Kats.¹
¹Children's Mercy Hospital, Kansas City, MO; ²University of Kansas Medical Center, Kansas City, KS
Background: Serial surveillance biopsies demonstrate post-transplant inflammation and fibrosis in long-surviving pediatric liver allografts. These changes can ultimately lead to cirrhosis and graft failure. However,…
