Abstract
Liver failure (LF) is serious liver damage caused by multiple factors, resulting in severe impairment or decompensation of liver synthesis, detoxification, metabolism, and biotransformation. The general prognosis of LF is poor with high mortality in non-transplant patients. The clinical treatments for LF are mainly internal medicine comprehensive care, artificial liver support system, and liver transplantation. However, none of the above treatment strategies can solve the problems of all liver failure patients and has its own limitations. Mesenchymal stem cells (MSCs) are a kind of stem cells with multidirectional differentiation potential and paracrine function, which play an important role in immune regulation and tissue regeneration. In recent years, MSCs have shown multiple advantages in the treatment of LF in pre-clinical experiments and clinical trials. In this work, we reviewed the biological characteristics of MSCs, the possible molecular mechanisms of MSCs in the treatment of liver failure, animal experiments, and clinical application, and also discussed the existing problems of MSCs in the treatment of liver failure.
