Effect of Different Dosage of Umbilical Cord-mesenchymal Stem Cells Through Peripheral Vein in Patients With ESLD

There is a rise in the prevalence of end-stage liver disease during the last decade. End-stage liver disease has become one of the leading causes of death in Western countries. Liver transplantation is the only curative treatment for patients with end-stage liver disease. However, the shortage of donor, high cost, and postoperative complications limit its wide application in clinical practice. At present, stem cell-based therapy has been developed as an alternative treatment for end-stage liver disease. Stem cells can be differentiated into a variety of cell types, and stem cell transplantation, mainly umbilical cord-mesenchymal stem cells, has attracted more and more attention in the treatment of end-stage liver disease. The investigators therefore conduct a randomised controlled trial to investigate the efficacy and safety of human umbilical cord tissue mesenchymal stem cells for the treatment of end-stage liver disease.
