摘　　要：背景:有研究报道中药葛根素具有减少骨吸收、促进骨形成的作用。目的:进一步验证中药葛根素对体外培养成骨细胞增殖的影响。方法:取新生大鼠的颅盖骨进行成骨细胞培养,取第3代细胞分别加入浓度为0,20,40,80和100μmol/L的葛根素+含体积分数10%胎牛血清DMEM培养基培养48 h。应用MTT法、碱性磷酸酶试剂盒及茜素红染色方法观察葛根素对体外培养成骨细胞的增殖、碱性磷酸酶活性及矿化结节形成的影响。结果与结论:与空白对照组比较,中药葛根素40,80μmol/L浓度组具有刺激成骨细胞增殖的作用;成骨细胞碱性磷酸酶活性检测显示葛根素在40μmol/L和80μmol/L浓度呈现明显的促进分化作用;在不同浓度葛根素中培养14 d可以清晰的观察到矿化组织形成,40μmol/L和80μmol/L葛根素培养的细胞矿化结节形成数量显著多于对照组。结果证实葛根素对体外培养的成骨细胞有明显的促进增殖作用。BACKGROUND：Studies have reported that puerarin can reduce bone resorption and promote bone formation. OBJECTIVE： To further explore the effects of puerarin at different doses on the proliferation of osteoblasts culturedin vitro. METHODS： Osteoblasts isolated from the cranium of newborn rats were culturedin vitro, and then passage 3 cels were cultured in DMEM medium with the presence of 0, 20, 40, 80 and 100 μmol/L puerarin＋10% fetal bovine serum for 48 hours. The viability of osteoblasts, alkaline phosphatase activity and mineral node formation were determined using MTT, alkaline phosphatase kit and alizarin red staining, respectively. RESULTS AND CONCLUSION：The viability of osteoblasts treated with puerarin at either 40 or 80 μmol/L was significantly higher than that of the control group. Alkaline phosphatase activity and the number of mineral modules were significantly increased in osteoblasts cultured with puerarin at 40 or 80 μmol/L when compared with the untreated cels. These findings demonstrate that puerarin is able to promote osteoblast proliferation in vitro.
