[Clinical research in cell therapy of liver diseases: progress and challenges].

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.慢性肝病发病率高，严重威胁人民群众健康，现有的内科综合治疗效果不佳。肝移植受限于肝源紧缺及移植后排异，不能满足临床需求。细胞治疗对于治疗慢性肝病展现出良好前景。近年来，国内外学者开展了多种细胞治疗危重肝病的临床前及临床试验，取得了一定的效果，为慢性肝病的治疗提供了新的方法。现就细胞治疗在慢性肝病治疗中的研究与应用进展进行综述，分别讨论各种类细胞治疗的研究现状、存在问题及挑战，并重点对间充质干细胞治疗慢性肝病的关键问题进行探讨。.
