e., bleeding, hematoma, infection, etc.) were observed and MG-132 purchase no elevation in the incidence of HCC was observed over a 192-week follow-up. In respect to short-term efficacy, the improvement in self-reported symptoms was

not different between the two groups. In respect to liver function at 1-4 weeks, the improvement in group A was superior to that in group B, as the improvement of ALB and TBIL levels and PT and MELD scores in group A were markedly superior to those in group B at 2-3 weeks after transplantation; however, ALT levels were not markedly changed. In respect to liver function at 1-48 weeks, the observed improvements were not maintained after 36 weeks. Furthermore, during the 192-week follow-up, results revealed no remarkable differences in the incidence of HCC or survival rate between the two groups. These finding

implied that autologous MMSC transplantation could not improve selleckchem the long-term prognosis of patients with liver failure caused by hepatitis B. Furthermore, in group A, no significant difference was observed in the incidence of HCC or survival rate at the different time points between patients with and without cirrhosis. Since cirrhosis is considered one of the most important risk factors for HCC and can lead to a high mortality for patients with hepatitis B,30, 31 our results provided evidence that autologous MMSC transplantation might exert protective effects for cirrhosis patients in regards to the occurrence of HCC and mortality. Based on the above results, we speculated that autologous MMSC transplantation was safe for patients with liver failure caused 上海皓元医药股份有限公司 by hepatitis B. Autologous MMSC transplantation had favorable short-term efficacy (from postoperative weeks 4 to 36) and played important roles in repair after acute liver injury as well as improved disease condition and mortality. Also, for patients with cirrhosis, autologous MMSC transplantation might exert better protective effects in regards to the occurrence of HCC and mortality, but could not markedly improve the long-term prognosis of these patients. In addition, the transfusion of MMSCs was

performed through the proper hepatic artery. However, it has been shown to be inappropriate to perform the transfusion through the hepatic artery,26 and transfusion through peripheral veins may achieve more favorable outcomes.12, 14 Furthermore, the limited number of MMSCs in the bone marrow from patients for transfusion32 and that the homing ability was difficult to increase are the main causes of the compromised efficacy of autologous MMSC transplantation, and this may be why our autologous MMSC transplantation did not achieve acceptable long-term effects on prognosis. In vitro proliferation of autologous MMSCs and multiple transplantations with MMSCs with high purity and high density may be the key factors for improving the efficacy of transplantation.
