Introduction: Hematopoietic stem cells are able to “transdifferentiate“ into parenchymal cells, however the regulation of this process is not yet elucidated. The present study was designed to investigate the extent of parenchymal chimerism after experimental and clinical gender mismatched liver transplantation. Methods: Rate and frequency of Y-chromosome containing hepatocytes was determined by Fluorescence-in-situ Hybridization (FISH) using a human or rat Y-chromosome specific probe. Biopsy samples from patients after full-size or partial liver transplantation were evaluated. In addition animal experiments were…
