HEPATOCYTE TRANSPLANTATION: CLINICAL EXPERIENCE AND POTENTIAL FOR FUTURE USE

摘要

Hepatocyte transplantation has been proposed as a method to support patients with liver insufficiency. There are three main areas where the transplantation of isolated hepatocytes has been proposed and used for clinical therapy. Cell transplantation has been used: 1) for temporary metabolic support of patients in end-stage liver failure awaiting whole organ transplantation, 2) as a method to support liver function and facilitate regenera- tion of the native liver in cases of fulminant hepatic failure, and 3) in a manner similar to gene therapy, as a “cellular therapy” for patients with genetic defects in vital liver functions. We will briefly review the basic research that leads to clinical hepatocyte transplantation, the published clinical experience with this experimental technique, and some possible future uses of hepatocyte transplantation. In The Lancet today, Jacob Lavee and colleagues1 describe a new law recently approved by Israel’s Parliament. The law will become eff ective in January, 2010, and will grant donor-card holders priority in organ allocation, with the aim of increasing the number of organ donations and reducing the length of transplantation waiting lists.
