In recent years there has been an increasing need for transplantation, but the number of donor livers available has increased only slightly, despite intensive public relations activities. New concepts in the field of transplantation, for instance the transplantation of living donor organs or the splitting of organs, are urgently required, to safeguard the treatment of patients with severe liver disease. The development and clinical application of cell therapy for patients with liver disease could soon present a significant enhancement of the therapeutic options. The aim of such cell therapy is to repair or improve the biological function of the chronically and acutely damaged liver. Even though systematic trials are not available, individual case reports and small series already show promising clinical results. Present concepts of cell therapy for liver diseases based on the use of primary hepatocytes have recently been considerably extended through new data on the biology of stem cells. The adult haematopoetic stem cell as a pool for hepatocyte grafts - what would be the perspectives for the clinical application? This book is the proceedings of the Falk Symposium No. 126 on `Hepatocyte Transplantation' (Progress in Gastroenterology and Hepatology Part III) held in Hannover, Germany, October 2-3, 2001, and is a forum for basic research, but also for questions concerning clinical applications in the field of hepatocyte transplantation.

Due to its efficacy in animal models, cellular therapy using human hepatocytes is being evaluated worldwide as an alternative to organ transplantation in patients with liver-based metabolic disease and acute liver failure. In Hepatocyte Transplantation: Methods and Protocols, an international panel of experts provide up-to-date laboratory and clinical techniques covering the many key areas necessary for successful transplantation, such as cryopreservation, quality assurance, detection of cell engraftment, and the future of the field with the development of foetal hepatoblasts and stem cell derived hepatocytes. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters in this volume present brief introductions to the material, lists of the necessary materials and reagents, readily reproducible, step-by-step laboratory protocols, and Notes sections which highlight tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Hepatocyte Transplantation: Methods and Protocols is an ideal guide for researchers setting out in the rapidly progressing field of hepatocyte transplantation, as well as those who already have experience with this new therapy for liver disease.

A major new reference work on Liver Transplantation written by the transplantation team of one of Asia's leading transplant centres with a foreword by Prof. Sir Roy Calne the liver transplantation pioneer and expert in immunosuppressant techniques. The book begins with an overview of transplantation team composition, international donor selection guidelines and donor management and goes on to discuss technique and management of DDLT, LDLT, Pediatric, Split, Domino and ABO-incompatible liver transplantation. Post-transplant management, immuno-suppression, follow-up, short and long-term complications and their outcomes, as well as recent advances in liver transplantation such as stem cell, hepatocyte and xenotransplantation, are also discussed.

It is thirty years since the technique of high-yield preparation of isolated hepatocytes, by collagenase perfusion of the liver, was published. The original method described by Berry and Friend has undergone many minor modifications by other workers, and the two-step procedure introduced by Seglen in 1976 has become the most frequent way to prepare hepatocyte suspensions. An important development introduced by Bissell in 1973 was the use of the cells as the first step in monolayer culture. The availability of the isolated hepatocyte preparation as cells in suspension or culture has undoubtedly facilitated research on the liver. This was emphasised in our book, published (with Dr. Greg Barritt) in 1990, which described in detail methods of preparation and the properties of the isolated hepatocytes. It also discussed the usefulness of the preparation for the study of intermediary and xenobiotic metabolism, calcium ion transport, and the growth and differentiation of hepatocytes in culture. The book also touched briefly on a range of specialised techniques, including peri fusion, subcellular fractionation, transplantation, cryopreservation and measurement of intracellular pH. Although standard procedures for the manipulation of hepatocytes have not changed a great deal in ten years, they have undoubtedly been refined. This applies particularly to hepatocyte culture techniques, cryopreservation, and even to preparation of hepatocyte suspensions, where it is now feasible to use purified enzymes. There is also much more emphasis on the use and study of human hepatocytes, particularly in the field of pharmacology and therapeutics.

The aim of this Special Issue is to review, understand, and evaluate new and exciting opportunities from the field on regenerative medicine, biomaterials, and stem cell research for the bioengineering of human liver grafts that can be applied for transplantation and personalized treatment of end-stage liver disease.The development of culture conditions for long-term expansion of LGR5+ intestinal stem cells as crypt-villus structures demonstrated the feasibility of deriving complex, organ-like structures in vitro from primary adult tissues, including the liver. Moreover, human pluripotent stem cells (hPSCs) can be applied to generate functionally maturated liver and bile duct epithelial cells.In this Special Issue, we welcome reviews and original papers focussing on hepatic cell sources, including adult hepatic stem cells, organoids, fetal and induced pluripotent stem cells, and primary cells (i.e., hepatocytes, cholangiocytes, and endothelial cells) and how these cells can be applied in tissue engineering strategies to generate implantable and personalized liver grafts. Potential topics include, but are not limited to, the following: liver tissue engineering, liver regeneration, graft repair, liver stem cells and organoids, bio-scaffolds, and 3D printing.We invite you to contribute original research papers, as well as comprehensive reviews, aligned with these themes, to advance and improve the actual state-of-the-art in liver bioengineering and providing new opportunities for the imminent medical problem of organ and tissue shortage for transplantation.

Hepatocyte transplantation is being evaluated as an alternative to orthotopic liver transplantation in the management of liver-based metabolic disorders and acute liver failure. The use of magnetic resonance imaging (MRI) as a non-invasive technique to monitor donor cell engraftment following transplantation was investigated. -- Studies were performed to optimise labelling conditions for human hepatocytes with clinically available superparamagnetic iron oxide nanoparticles (SPIOs). Labelling with 50 g Fe/ml of SPIOs in culture had minimal effect on cell metabolic function and allowed label incorporation at sufficient levels for in vitro detection on a 7-T MRI system. Intrasplenic transplantation of human hepatocytes labelled with SPIOs was performed in non-obese diabetic/severe combined immunodeficient (NOD-SCID) mice. Two hours after hepatocyte transplantation, SPIO-labelled hepatocytes could be imaged in the liver. -- Incorporation of the contrast agent in hepatocytes was significantly improved using the transfection agents poly-L-lysine and protamine sulphate (PS). A rat model of acute liver failure induced by D(+)-galactosamine was used to study the engraftment potential of the labelled cells in vivo. At day 7 there was a decrease in the MRI signal intensity in the liver of rats transplanted with SPIO-PS complex-labelled cells. However, histology demonstrated that the iron in the liver was in Kupffer and endothelial cells in periportal areas rather than hepatocytes, indicating clearance of labelled hepatocytes. Donor cells were detected in the spleen of animals receiving SPIO-PS labelled hepatocytes, suggesting that some of the cells were retained in the spleen in this model. -- As an alternative approach, 99mTechnetium-labelled galactosyl-serum albumin, which binds to asialoglycoprotein receptors on the surface of hepatocytes was also investigated.
