RESUMO
Objective To investigate the effects of BMP2 in the co-culture system of hBMSCs and hUVECs.Methods Based on the co-culture system of cells,a simple culture group (hBMSCs group),a combined culture group (BMSCs + hUVECs group) and a BMP2 silenced group (BMSCs + BMP2 silenced hUVECs) were established.On days 4,6,8,10,cells were counted for drawing cell growth curves.In addition,ALP and OC expression in BMSCs was detected in each group.Results At each time point,cell number in the BMSCs + hUVECs group were significantly greater than in the BMSCs group,while the BMP2 silenced group were in the median.ALP and OC expression in the BMSCs + hUVECs group were significantly greater than in the BMSCs group,while the BMP2 silenced group were in the median.Conclusion BMP2 plays an important role in the co-culture system,which can promote osteogenic differentiation and the growth of BMSCs.
