文题释义:
含药血清:
中药血清药理学是为了研究中药复方制剂而诞生的一种新的体外实验方法,即将受试药物经口给予动物后以含药血清代替中药粗提物作为药物源加入体外反应系统中研究其药理作用,因此目前多数学者认为血清药理学方法可以较客观地反映中药的药效。
细胞分化:是程序控制的有序有规律过程,其结果除取决于细胞在基因表达上的时空差异,还受细胞外环境的影响和调控,且有时这种外部控制条件或环境对形成特定细胞有着决定性作用。近年来,含药血清实验方法引起越来越多研究者的重视。通过天然中药、中药提取物及中药复方干预骨髓间充质干细胞增殖分化,运用中药血清药理学手段,从分子、细胞、基因水平角度研究中药的作用及作用机制,使骨髓间充质干细胞向更宽、更广领域参与骨代谢疾病、骨缺损、骨折不愈合及迟缓愈合等各类疾病的治疗,充分发挥其临床应用价值。

 

摘要
背景:
骨髓间充质干细胞是存在于骨髓中的一种具有多向分化潜能的干细胞,当受到含药血清作用时,其所涉及的多条信号通路上的基因表达会发生改变。
目的:考察复方接骨片和壮骨片含药血清在骨髓间充质干细胞体外分化过程中的作用。
方法:取60只SD大鼠,随机分为复方接骨片组、壮骨片组、两药联用组和空白对照组,制备含药血清。分离培养SD大鼠骨髓间充质干细胞,于培养瓶中加入不同的含药血清,培养24 h后,RT-PCR法检测BMP-2、Runx2、VEGF及Akt mRNA的表达,Western blot法检测BMP-2、Runx2、VEGF及Akt蛋白的表达。
结果与结论:①与对照组比较,复方接骨片组及两药联用组Akt和VEGF mRNA及蛋白的表达明显升高(P < 0.05或P < 0.01);②壮骨片组与对照组相比,Akt和VEGF mRNA及蛋白表达差异无显著性意义(P > 0.05);③与对照组比较,复方接骨片组BMP-2和Runx2 mRNA及蛋白表达升高(P < 0.05);④与对照组相比,壮骨片组及两药联用组BMP-2及Runx2 mRNA及蛋白表达均显著增加(P < 0.01);⑤结果表明,复方接骨片及壮骨片含药血清可在骨髓间充质干细胞体外分化通路中起到协同促进骨髓间充质干细胞向血管内皮细胞及成骨细胞分化的作用。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells in the bone marrow. Drug-containing serum treatment may be followed by a variation in the expression of genes involved in multiple signaling pathways.
OBJECTIVE: To study the effect of compound Jiegu Tablets and Zhuanggu Tablets on the differentiation of BMSCs in vitro
METHODS: Sixty Sprague-Dawley rats were randomized into Jiegu group, Zhuanggu group, combined group and blank control group. Different drug-containing sera were prepared and used to culture BMSCs isolated from the rat bone marrow. RT-PCR and western blot assay were used to detect the expression of BMP-2, Runx2, VEGF and Akt at mRNA and protein levels, respectively, at 24 hours after culture.
RESULTS AND CONCLUSION: Compared with the blank control group, the expression levels of Akt and VEGF mRNA and protein were significantly increased in the Jiegu group and combined group (P < 0.05 or P < 0.01), but showed no difference in the Zhuanggu group (P > 0.05). Compared with the blank control group, the expression levels of BMP-2 and Runx2 mRNA and protein were significantly increased in the Jiegu group (P < 0.05) and very significantly increased in the Zhuanggu group and combined group (P < 0.01). These findings indicate that compound Jiegu Tablets and Zhuanggu Tablets containing sera lead to synergistic effects on theBMSCs differentiation into vascular endothelial cells and osteoblasts in vitro
