Endothelial Cell Cytoskeleton Rearrangement (ECCSKR) and Endothelial to Mesenchymal Transition (EndoMT) in Liver Allografts Following Acute Rejection (AR): Its Significance on the Development of Liver Fibrosis (LF) and Graft Survival
B. H. Ozdemir¹, G. Ozgun¹, E. H. Ayvazoglu Soy², N. Haberal¹, G. Moray², M. Haberal²
¹Pathology, Baskent University, Ankara, Turkey, ²Transplantation, Baskent University, Ankara, Turkey
