摘要
目的:研究骨康胶囊对体外培养的SaOS-2成骨肉瘤细胞增殖、分化及矿化的影响。方法:培养成骨肉瘤细胞SaOS-2,设立对照组、不同浓度的骨康胶囊组(生药浓度为1、10、100、200、400、800 mg/L)及维生素D3组,采用MTT法检测SaOS-2细胞增殖能力;选择10、100及200 mg/L骨康胶囊浓度处理SaOS-2细胞,对-硝基苯磷酸盐法(PNPP法)检测SaOS-2细胞碱性磷酸酶(ALP)活性,ELISA法检测SaOS-2细胞骨钙素(OTC)和钙离子(Ca^(2+))分泌能力,采用细胞钙茜素红染色法对成骨细胞进行染色、观察SaOS-2细胞矿化能力。结果:与对照组相比,骨康胶囊在体外可以显著促进成骨肉瘤细胞的增殖(P<0.01),当骨康胶囊浓度为200 mg/L时作用最大,此后随着骨康胶囊浓度增大对SaOS-2细胞增殖的促进作用有明显减弱的趋势;在10、100、200 mg/L浓度范围内,骨康胶囊剂量依赖性地增加SaOS-2细胞ALP活性、促进OTC和Ca^(2+)的分泌及细胞矿化结节形成(P<0.05或P<0.01)。结论:骨康胶囊对体外培养的SaOS-2细胞的增殖、分化和矿化有明显的促进作用。
Objective： To study the effects of Gukang capsule on cell proliferation,differentiation and mineralization of human osteoblast-like SaOS-2 cells cultivated in vitro. Methods： SaOS-2 cells were cultivated. The control group,Gukang capsule group with different concentrations（ The biological concentrations were 1,10,100,200,400 and 800 mg/L respectively） and Vitamin D3 group were set up,and cell proliferation was tested by MTT assay. The SaOS-2 cells were treated with the Gukang capsule（ 10,100 and 200 mg/L respectively）,and the Alkaline phosphatase（ ALP） activity was measured by PNPP method. Secretion of osteocalcin（ OTC） and Ca^2＋was detected by ELISA assay.Osteoblasts were stained with calcium alizarin red staining method and mineralization of SaOS-2 cells was observed. Results： Compared with the control group,Gukang capsule could significantly promote proliferation of SaOS-2 cells in vitro（ P〈0. 01）,and increase ALP activity in a dose-dependent manner（ P〈0. 01）. Moreover,it could also increase the secretion of OTC and Ca^2＋（ P〈0. 05,P〈0. 01）,and significantly promote the formation of osteoblast mineralization nodules（ P〈0. 05）.Conclusions： Gukang capsule could increase cell proliferation,differentiation and mineralization activities in SaOS-2 cells cultivated in vitro,which may contribute to its therapeutic effects.
