PT and MELD scores of patients in group A were markedly improved, compared with those in group

B, at week 3 after transplantation MI-503 concentration (Table 2; Fig. 2C,D). Furthermore, in both groups, there were no significant differences in PT or MELD scores between the cirrhosis and noncirrhosis subgroups (Table 3). Liver function comparisons from baseline to 48 weeks after transplantation (Table 4; Fig. 3) indicated that there were no marked differences in ALT levels between the two groups (Table 4(TBL4)). ALB levels of patients in group A were significantly superior to those in group B at 3-24 weeks after transplantation, and significant deviations were not found after 24 weeks (Table 4; Fig. 3A). The improvement in TBIL levels and PT scores of group A was markedly superior to those of group B only at 4-12 week after transplantation (Table 4; Fig. 3B,C). The improvement of MELD scores of group A was markedly superior to that of group B at 3-36 weeks after transplantation (Table 4; Fig. 3D). In regards to long-term prognosis, only one patient in group A developed HCC at 20 weeks after transplantation, and nine patients in group B developed selleck chemical HCC throughout the 48-week follow-up; there were no significant deviations between these two groups (P = 0.107) (Fig. 4A). Furthermore, the survival rate of patients in group A was better than in group B, but significant deviations were not observed from 12 to 192 weeks of follow-up (P = 0.715) (Fig. 4B). No HCC

was found in the subgroup of patients with cirrhosis from group A, and only one incidence of HCC was observed at 20 weeks after transplantation in the subgroup of patients without cirrhosis from group A; significant deviations were not found. There were no significant deviations between these two subgroups for

survival rate (P = 0.915) (Fig. 4C). MMSCs demonstrate multipotentiality and can promote liver regeneration, secrete cytokines/growth factors, inhibit inflammation, inhibit activation of liver astrocytes, block the production of extracellular matrix (ECM), and facilitate the degradation of excessive ECM, leading to improvement of chronic hepatitis B, impediment of liver fibrosis, and repair of injured liver tissues.20 Great find more progress has been made in the treatment of liver diseases with the use of autologous MMSC transplantation and has included basic research and clinical studies.11-14, 21-24 Yet, there are still a number of problems requiring resolution in clinical practice, including the route of MMSC administration, the number of cells used for transplantation, and homing ability that may affect the efficacy of transplantation.25-27 In our previous research, we explored the bionomics of MMSCs from patients with hepatitis B.22, 28, 29 Based on these studies, we investigated the safety, short- and long-term therapeutic effects, and prognosis of a single transplantation of autologous MMSCs in patients with liver failure caused by hepatitis B.
