ObjectiveTo 在骨头髓的增长上调查 icariin 的效果在 Sprague-Dawley (SD ) rats.MethodsBMSCs 的间充质的干细胞(BMSC ) 与微分时间从 SD 老鼠骨头髓被获得支持者方法。它的特征通过区别房间表面抗原和多系(osteo/adipo/chondo ) 被识别区别潜力。3-(4,5-Dimethylthiazol-2-yl )-2,5-diphenyltetrazolium 溴化物(MTT ) 方法和 5-Bromo-2-Deoxyuridine (BrdU ) 加入被使用在 BMSC 增长上检测 icariin 的效果。流动 cytometry 被用来检测 BMSC 的增长索引。mRNA 水平和 -catenin 的分发被实时聚合酶链反应(PCR ) 和分别地染色的 Immunofluorescent 评估。西方的污点被用来检测贝它(GSK-3 ) , phospho 肝糖 synthase kinase-3 贝它(pGSK-3 ) 和 cyclinD1.ResultsIcariin 支持了的 -catenin, 肝糖 synthase kinase-3 的蛋白质表示层次在 0.05-2.0 mg/L 的集中的 BMSC 增长。BMSC 的 BrdU 积极房间的百分比从 40.98% ~ 70.42% 被增加,并且增长索引价值与 0.05 mg/L icariin 的处理从 8.9% ~ 17.5% 被增加,意义价值两个都是它不到 0.05。与控制组,全部、原子的 -catenin 蛋白质,以及 -catenin mRNA 相比表示,都与 icariin 处理被增加。同时, GSK-3 和 cyclinD1 蛋白质表情的 phosphorylation 水平也与现在的学习的调查结果表明了的 icariin treatment.ConclusionThe 在 BMSC 被增加 icariin 的那低剂量能支持 BMSC 增长。Wnt/-catenin 小径的激活涉及这个过程。
OBJECTIVE: To investigate the effect of icariin on proliferation of bone marrow mesenchymal stem cells(BMSCs) in Sprague-Dawley(SD) rats.METHODS: BMSCs were obtained from SD rat bone marrow with differential time adherent method. Its characteristic was identified through differentiation cell surface antigens and the multi-lineage(osteo/adipo/chondo) differentiation potential. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) method and 5-Bromo-2-Deoxyuridine(Brd U) incorporation were applied to detect the effect of icariin on BMSCs proliferation.Flow cytometry was used to detect proliferation in-dex of BMSCs. The m RNA level and the distribution of β-catenin were evaluated by Real-time Polymerase Chain Reaction(PCR) and Immunofluorescent staining respectively. Western blot was used to detect protein expression levels of β-catenin, glycogen synthase kinase-3 beta(GSK-3β), phospho-glycogen synthase kinase-3 beta(p GSK-3β)and cyclin D1.RESULTS: Icariin promoted BMSCs proliferation at the concentration of 0.05-2.0 mg/L. The percentage of Brd U positive cells of BMSCs was increased from40.98% to 70.42%, and the proliferation index value was increased from 8.9% to 17.5% with the treatment of 0.05 mg/L icariin, which significance values were both less than 0.05. Compared with the control group, total and nuclear β-catenin proteins, as well as β-catenin m RNA expression, were all increased with icariin treatment. Meanwhile, the phosphorylation level of GSK-3β and cyclin D1 protein expressions were also increased in BMSCs with icariin treatment.CONCLUSION: The findings of the present study demonstrated that low dosage of icariin could promote BMSCs proliferation. The activation of Wnt/β-catenin pathways was involved in this process.
