Radiosensitive Cell Population Prolongs Graft Survival of Vascularized Composite Allografts in Non-Human Primates.
M. Uluer, J. Woodall, W. Hassanein, U. Drhu, B. Bojovic, A. Nam, S. Bartlett, R. Barth.
University of Maryland School of Medicine, Baltimore, MD.
Background: Vascularized composite allografts (VCA) containing vascularized bone marrow (VBM) prolong graft survival. To help elucidate this protective immunomodulatory effect, we irradiated donor facial VCA…

Acute Allograft Glomerulopathy: A Distinct Form of Cellular Rejection.
O. AL-Badri, M. Alexander, F. Cosio, L. Cornell.
Mayo Clinic, Rochester, MN.
Background: Acute allograft glomerulopathy (AAG) is an unusual glomerular lesion of allografts with endocapillary hypercellularity, markedly enlarged endothelial cells occluding the capillary lumen, and absence…
