Hepatocyte Isolation and Transplantation in the Pig
Abstract:Hepatocyte transplantation (HTX) has received great expectation for the treatment of a wide spectrum of liver diseases. Considering the severe shortage of human livers for hepatocyte isolation, porcine hepatocytes are an attractive alternative to normal human hepatocytes. To develop such therapy, establishment of an efficient hepatocyte isolation and transplantation model that enables accurate assessment of safety and efficacy of HTX is extremely important. Porcine hepatocytes were isolated from a surgically removed liver segment with a four-step retrograde perfusion using dispase and collagenase. The resultant hepatocytes of >84% viability were used for transplantation experiment in a pig model of acute liver failure induced by intravenous administration of D-galactosamine (D-gal) (0.5 mg/kg). Twenty-four hours after D-gal injection, transplantation of freshly isolated porcine hepatocytes (1 × 109) was safely conducted and prolonged the survival of D-gal-treated pigs. We describe an efficient porcine hepatocyte isolation and subsequent cell transplantation in pigs with D-gal-induced liver failure.

- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
