Objective:To study the effects of ascorbic acid on BMP-2 mRNA expression of osteoblast cell sheets.Methods:Rat os-teoblasts were primaryly cultured and identified;osteoblast cell sheets were built by physical scraping method in vitro;the osteoblast cell sheets were cultured with 1 5,50 and 85 mg/L ascorbic acid for 1 and 2 weeks respectively,and the expression of BMP-2 mRNA of the cell sheets was detected by RT-qPCR.Results:The obtained cells were conformed to be osteoblasts.The osteoblast cell sheets could be rolled into tube in vitro.The expression of BMP-2 mRNA of osteoblast cell sheets in experiment group,whether in week one or week two was higher than that in control group,50 mg/L group showed the highest expression(first week P <0.05;second week P>0.05);the expression of any group in week two was higher than that in week one(P <0.05).Conclusion:Ascorbic acid may pro-mote the expression of BMP-2 mRNA in osteoblast cell sheets.
