The work of liver stem cell biologists, largely carried out in rodent models, has now started to manifest in human investigations and applications. We can now recognize complex regenerative processes in tissue specimens that had only been suspected for decades, but we also struggle to describe what we see in human tissues in a way that takes into account(More)
High titre replication of human cytomegalovirus (HCMV) in cell culture is restricted to primary human fibroblasts. During acute infection in vivo, HCMV nucleic acids and antigens have been found in various organs. Using only morphological criteria, inconsistent data have been reported about the cell types that can be infected by HCMV. In particular, the(More)
BACKGROUND & AIMS Progressive familial intrahepatic cholestasis (PFIC), an inherited liver disease of childhood, is characterized by cholestasis and either normal or increased serum gamma-glutamyltransferase activity. Patients with normal gamma-glutamyltransferase activity have mutations of the FIC1 locus on chromosome 18q21 or mutations of the BSEP gene on(More)
BACKGROUND & AIMS During endotoxemia, expression of inducible nitric oxide synthase (iNOS) and nitric oxide production in the liver is increased. NO has been suggested to have a hepatoprotective function. The aim of this study was to investigate the distribution of iNOS and the effect of different NO synthase inhibitors on liver damage and hemodynamics(More)
Interest in hepatic ductular reactions (DRs) has risen in recent years because of a greater appreciation of their potential roles in regeneration, fibrogenesis, and carcinogenesis. However, confusion exists because there is significant, but often unappreciated diversity at the tissue, cellular, and subcellular levels in DRs of different diseases and stages(More)
In contrast to traditional static cold preservation of donor livers, normothermic machine perfusion may reduce preservation injury, improve graft viability and potentially allows ex vivo assessment of graft viability before transplantation. We have studied the feasibility of normothermic machine perfusion in four discarded human donor livers. Normothermic(More)
UNLABELLED Quantitative data on the expression of multiple factors that control angiogenesis in hepatocellular carcinoma (HCC) are limited. A better understanding of the mechanisms underlying angiogenesis in HCC will improve the rational choice of anti-angiogenic treatment. We quantified gene and protein expression of members of the vascular endothelial(More)
BACKGROUND/AIMS Biliary strictures are a serious cause of morbidity after liver transplantation. We have studied the role of altered bile composition as a mechanism of bile duct injury after human liver transplantation. METHODS In 28 liver transplant recipients, bile samples were collected daily posttransplantation for determination of bile composition.(More)
BACKGROUND & AIMS Although regeneration of intrahepatic bile ducts has been extensively studied and intrahepatic progenitor cells have been identified, few studies have focussed on the extrahepatic bile duct (EHBD). We hypothesized that local progenitor cells are present within the EHBD of humans. Human EHBD specimens (n = 17) were included in this study.(More)
