淫羊藿苷对人成骨细胞增殖及OPG蛋白表达的实验研究
Experimental study on the mechanism of icariin improving human osteoblasts proliferation and the expression of OPG protein
摘要
Abstract
Objective:To establish the human osteoblasts culture system in vitro,observe the effects of icariin on human osteoblasts proliferation and expression of OPG protein,and to explore the mechanism of promoting bone formation about human osteoblast in icariin.Methods:The femoral cancellous bone pieces were obtained from the operation.The enzyme digestion method was used for culturing.The third passage of human osteoblast was taken for experiments.The cells were divided into four groups,the control group was treated with 15％NCS-DMEM-F12 (1:1 ),the experimental groups were respectivelytreated with 10-6, l0-8, l0-10 mol/L icariin.The MTT method was used to observe the proliferation of human osteoblast on 1,3,5,7,9 d; in 8,10,12 d, western blot was used to determine the expression of OPG protein on human osteoblast.Results :① Results of MTT:the icariin promoted the proliferation of human osteoblast.There was a concentration-response relation, while with the concentration of icariin increased, the ability was more obvious.There was statistically difference between 10-6 mol/L icariin group (0.402±0.033) and the control group(0.268±0.031 ) (P＜0.05).In the timely research,as the time prolong, the number of human osteoblast were more.At the fifth day, the human osteoblast entered rapid growth period, and access the growth platform stage;the icariin began to promote the proliferation of human osteoblast from the fifth day, which almost maintained to the 7th day and the 9th day,and most obvious in the 9th day.There was statistically difference between 10-6mol/L icariin group (0.402±0.033) and the control group (0,268±0.031) at the 9th day.②The results of OPG protein expression:in the control group,the expression of OPG protein was detected at the 8th day (1.01 ±0.08),and reached the expression peak (1.80±0.10), there was statistically different (P＜0.05).In the different days and different concentration icariin groups, the expressions of OPG protein were all inferior to the control group.While the concentration decreasing, the expression was less.There were statistically difference (P＜0.05).At the day 12, there was no significant difference of OPG protein expression between the 10-6mol/L icariin group and the 10-8mol/L icariin group (P＞0.05).Conclusion: The effect of icariin promoting the proliferation of human osteoblast maybe is one of the mechanisms of improving the bone formation on human osteoblast.关键词
