Abstract:

Acute liver failure (ALF) has a poor prognosis and, despite intensive care support, reported average survival is only 10‐40%. The most common causes responsible for ALF are viral hepatitis (mainly hepatitis A and B) and acetaminophen poisoning. Hepatic transplantation is the only appropriate treatment for patients with unlikely survival with supportive care alone. Survival rates after transplantation can be as high as 80‐90% at the end of the first year. However, there is a shortage of donors and is not uncommon that no appropriate donor matches with the patient in time to avoid death. Therefore, new technologies are in constant development, including blood purification therapies as plasmapheresis, hemodiafiltration, and bioartificial liver support. However, they are still of limited efficacy or at an experimental level, and new strategies are welcome. Accordingly, cell transplantation has been developed to serve as a possible bridge to spontaneous recovery or liver transplantation. Xenotransplant of adult hepatocytes offers an interesting alternative. Moreover, the development of transgenic pigs with less immunogenic cells associated with new immunosuppressor strategies has allowed the development of this area. This article reviews some of the newly developed techniques, with focus on xenotransplant of adult hepatocytes, which might have clinical benefits as future treatment for ALF.

More about this publication?
  • The importance of translating original, peer-reviewed research and review articles on the subject of cell therapy and its application to human diseases to society has led to the formation of the journal Cell Medicine. To ensure high-quality contributions from all areas of transplantation, the same rigorous peer review will be applied to articles published in Cell Medicine. Articles may 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, and stem cells, among others. Basic clinical studies and immunological research papers may also be featured if they have a translational interest. To provide complete coverage of this revolutionary field, Cell Medicine will report on relevant technological advances and their potential for translational medicine. Cell Medicine will be a purely online Open Access journal. There will therefore be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow your work to be disseminated to a wider audience and also entitle you to a free PDF, as well as prepublication of an unedited version of your manuscript.
