Abstract:
Objective To (e)xplore inhibition of endothelial progenitor cells (EPCs) against hepatic vein thrombosis after allogeneic bone marrow transplantation (BMT).Methods Balb/c mice were randomly divided into three groups: (1) BMT group [Balb/c mice were injected intravenously with 5 × 106 bone marrow cells after total body irradiation (TBI)]; (2) EPCs co-transfusion with bone marrow cells group: 5 × 105 EPCs were infused into recipient mice simultaneously; (3) Normal control group.Liver index was detected on the day 0,5,10,15 and 20 after transplantation.Hepatic vein thrombosis,hepatic cells and vascular endothelial damage were observed under the light microscopy after H&E staining.The injury of liver cells,liver veins,hepatic sinusoidal endothelial cells (SECs)and platelet adhesion conditions were observed under a transmission electron microscope (TEM).The proportion of activated platelets and TNF-α concentration in peripheral blood were detected by using flow cytometry.Results On the day 0,5,10,15 and 20 after transplantation,the proportion of activated platelets,liver index and TNF-α concentrations in BMT group and EPCs co-transfusion group showed an upward trend,peaked on the 15th day,and then decreased.However,they were still significantly higher than those in normal control group (P＜0.05).The above parameters in EPCs co-transfusion group at each time point were significantly lower than those in BMT group (P＜0.05).As compared with BMT group,platelet adhesion decreased,hepatic vein thromboses were reduced,hepatocyte swelling and necrosis were alleviated,and liver damage repaired rapidly in EPCs co-transfusion group.Conclusion EPCs co-transfusion with bone marrow cells could inhibit the hepatic veins thrombosis and ameliorate liver damage significantly.
