Hepatocyte transplantation: State of the art

Advances in biotechnology have allowed hepatocyte transplantation as a relevant proposition to treat liver disease. This procedure may change the crescent mortality in liver transplantation waiting lists due global organ shortage. Recent clinical trials have described promising results of hepatocyte transplantation for acute, acute-on-chronic and metabolic liver disease. In this report, we discuss progresses regarding hepatocyte culture, cryopreservation systems, hepatocyte immortalization, suitable recipient site for hepatocyte engraftment, cell differentiation and fusion into hepatocytes, current clinical trials, and summarize the bioartificial liver systems. These progressions motivate expectation concerning hepatocyte transplantation as a consistent therapy for liver disease.
