摘要
目的:研究银杏叶提取物(ginkgo biloba extract,GBE)对大鼠的骨髓间充质干细胞(bone marrow mesenchymal stem cells,BMSCs)增殖及成骨分化过程的影响。方法:将不同浓度的GBE作用于第3代BMSCs,通过CCK-8(Cell Counting Kit-8)法及流式细胞仪法检测其对细胞增殖活性变化的影响,通过茜素红染色及碱性磷酸酶(Alkalinet phosphatase,ALP)法判定其对细胞成骨能力的影响。RT-PCR检测成骨相关基因骨形成蛋白2(bone morphogenetic protein-2,BMP-2)、Runx2(runt-related transcription factor2)的mRNA的表达。结果:不同浓度的GBE对BMSCs的增殖无明显影响,但能使细胞处于S期,显著促进ALP的表达,在浓度为150mg/L时表达最多。其成骨相关基因BMP-2、Runx2的mRNA表达也相对增高。结论:银杏叶提取物对骨髓间充质干细胞的成骨分化具有积极意义。
