Therapeutic Strategy and the Role of Mesenchymal Stromal Cells for ABO Incompatible Liver Transplantation

Overview

The purpose of this study is to determine whether MSCs are safe and effective in reducing the primary nonfunction (PNF), acute rejection and Ischemic-type Biliary Lesions (ITBLs) morbidity in ABO-incompatible Liver Transplantation.

ABO incompatible liver transplantations is considered to be a rescue option in emergency transplantation.The A、B antibodies to grafts bind to the graft endothelium and activate complement, which attracts and activates neutrophils and platelets and increases the permeability of the endothelium. The neutrophils exude, the platelets aggregate, and the small vessels of the graft get thrombosed, resulting in ischemic damage,leading nonfunction grafts.In addition, if the A、 B antibodies remain high level, it can lead to acute humoral immune rejection. A lot of research confirmed that the ABO incompatible is a risk factor of postoperative short- and long-term survival. And mesenchymal stromal cells (MSCs) are characterized by the properties of immunosuppressive and regenerative properties, which make MSCs great attractive in treating immunological diseases (including transplant rejection) and organ/tissue ischemic injury. So we conduct this clinical study,to confirm the effect of MSCs in ABO incompatible liver transplantation by comparing the incidence of primary nonfunction, acute rejection, biliary complications and survival rates.
