ABSTRACT

Objective To explore the effect of the association of low molecular heparin and Galectin-3 on the cell migration and cell proliferation of vascular endothelial cell from mesenchymal stem cells.Methods Depending on the administration, this study was divided into four groups: low molecular weight heparin group, adding 20 mg/L low molecular weight heparin into the cells;Galectin-3 group, adding 5 mg/L Galectin-3 into the cells;combination group, adding 20 mg/L low molecular weight heparin and 5 μg/ml of Galectin-3 into the cells;control group, equal volume of PBS buffer into the cells.The proliferation of vascular endothelial cell was to be detected by EdU incorporation,the cell growth cycle of vascular endothelial cell was to be detected by flow cytometry,and the cell migration of vascular endothelial cell was to be detected by scrath test.Then to investigate the effect of different conditions on the migration and proliferation of vascular endothelial cell.Results The OD490 of MWH group, Galectin-3 group, combined group and control group were (0.285±0.018), (0.297±0.041), (0.351±0.016), and (0.233±0.005) respectively, which indicates that the combined group could increase the cell proliferation significantly(P<0.05).Cultured for 24 hours, the cell migration rate was(42.02±7.62), (45.82±3.96), (68.53±11.22),and (34.21±3.99), suggesting that combined group have the largest cell migration(P<0.05).Conclusion The association of low molecular heparin and Galectin-3 could improve the cell migration and cell proliferation of vascular endothelial cell from esenchymal stemcells significantly.
