RESUMEN
The high incidence of chronic liver disease is a serious threat to public health, and the current comprehensive internal medicine treatment is ineffective. Liver transplantation is limited by the shortage of liver source and post-transplant rejection, and thus unmet the clinical needs. More importantly, cell therapy shows great promise for the treatment of chronic liver disease. Over recent years, domestic and foreign scholars have carried out a variety of cell therapy preclinical and clinical trials for critical liver disease, and achieved certain results, providing new methods for the treatment of chronic liver diseases. This review discusses the cell therapy research status and application progress, various existing problems and challenges, and key issues of mesenchymal stem cells in the treatment of chronic liver diseases.
