Abstract
Incidence and mortality of liver disease has increased globally in recent years. Orthotopic liver transplantation is a well-developed, effective therapy even for the end-stage liver diseases. However, the application of the technique is limited by the short supply of donors and the complexity of orthotopic liver transplantation. Therefore, hepatocyte transplantation as a new therapeutic option was developed. Unfortunately, the routine supply of high quality human hepatocytes was also restricted and the liver donor was lacking, too. Thus, exploration and study for available and renewable sources of nondonor hepatocytes are both necessary and important. Researches have proved that nondonor hepatocyte-like cells can be derived from various types of cells including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), liver stem cells (LSCs), fibroblasts by lineage reprogramming, hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). In this review, we describe recent advances in the field of the cell therapy in liver regeneration. In addition, we also discuss the existing restrictions in these types of therapies and ongoing developments.
