Human hepatocyte transplantation: Worldwide results

The conception (1) and animal modeling (2) of hepatocyte transplantation along with a partial listing of human hepatocyte infusions over the last 13 years have been detailed in authoritative reviews (3-8). However, to adequately best represent the worldwide effort of moving from highly successful clinical solid liver transplants "back to" isolated hepatocyte therapy requires repeating important concepts with explanations of how or why not animal experimental data translate to human experience. This overview summarizes 78 human clinical hepatocyte transplant experiences authenticated by the authors (Tables 1-3). The human cell infusion experiences are categorized by liver disease treated (metabolic, chronic, and acute liver failure), and these are accompanied by seminal in vitro and in vivo experimental data.
