文题释义:
骨向分化:
是指间充质干细胞在特定条件下,可被诱导为成骨细胞,此功能多用于骨病,如骨质疏松症的防治。通过促进间充质干细胞骨向分化可促进成骨细胞数量、分化及矿化,也可用于骨组织工程研究。
全骨髓贴壁法的特点:全骨髓贴壁法利用骨髓间充质干细胞的贴壁特性将其与造血细胞分离,通过换液、传代进一步纯化和扩增。与免疫磁珠法和密度梯度离心法相比,该法操作简便,对细胞干预小,提取过程中最大程度地保留了骨髓中其他干细胞和基质细胞所分泌的生长因子,利于原代细胞的贴壁及生长。

 

摘要
背景:
骨髓间充质干细胞参与骨形成,研究表明二仙汤能防治骨质疏松症,但对去卵巢大鼠骨髓间充质干细胞的作用并不清楚。
目的:通过研究二仙汤对骨质疏松大鼠骨髓间充质干细胞增殖及骨向分化的影响,探讨二仙汤防治骨质疏松与骨髓间充质干细胞之间的关系。
方法:将大鼠随机分为6组,分别为假手术组、模型组、雌激素组、二仙汤高、中、低剂量组。以去卵巢法复制大鼠骨质疏松模型,除假手术组外,其他各组均手术彻底摘除卵巢。假手术组、模型组大鼠灌胃生理盐水,雌激素组大鼠灌胃戊酸雌二醇(0.08 g/L),二仙汤给药组大鼠灌胃二仙汤提取液(含生药量分别为1.2,0.8,0.4 g/mL),给药剂量为10 mL/kg,连续给药90 d。全骨髓贴法分离骨髓间充质干细胞,MTT法绘制细胞生长曲线,碱性磷酸酶检测试剂盒检测细胞碱性磷酸酶活力,茜素红染色法检测细胞钙结节变化。
结果与结论:与模型组相比,高、中、低剂量二仙汤均可显著提高去卵巢大鼠骨髓间充质干细胞的增殖能力(P < 0.01);高、中、低剂量二仙汤明显改善去卵巢大鼠骨髓间充质干细胞碱性磷酸酶活力(P < 0.05,P < 0.01),中剂量二仙汤的改善作用最为显著(P < 0.01);高、中剂量二仙汤可促进去卵巢骨质疏松大鼠骨髓间充质干细胞钙结节的形成(P < 0.01)。结果证实,改善骨质疏松大鼠骨髓间充质干细胞增殖、骨向分化能力是二仙汤治疗骨质疏松症的内在机制之一。

Abstract:

BACKGROUND: Some studies have shown that bone marrow mesenchymal stem cells (BMSCs) are involved in bone formation. Erxian Decoction can treat osteoporosis, but its relationship with BMSCs in ovariectomized rats is not yet clear.
OBJECTIVE: To reveal the relationship between Erxian Decoction and BMSCs by exploring the effect of Erxian Decoction on proliferation and differentiation of BMSCs in rats with osteoporosis.
METHODS: Sprague-Dawley rats were randomly divided into six groups: sham group, model group, estrogen group, high-dose Erxian Decoction group, middle-dose Erxian Decoction group and low-dose Erxian Decoction groups. Ovariectomy was performed to establish rat osteoporosis models in all the groups except the sham group. The rats in the sham group and model group were given normal saline via gavage, and those in the estrogen group were fed with estradiol valerate (0.08 g/L). Rats in the high-, middle- and low-dose groups were given high (1.2 g/mL), middle (0.8 g/mL) and low (0.4 g/mL) concentrations of Erxian Decoction extracts at a dose of 10 mL/kg, for 90 continuous days. BMSCs were isolated by whole bone marrow adherent method, MTT method was used to draw the growth curve of BMSCs, alkaline phosphates kit was used to detect alkaline phosphatase activity, and alizarin red staining was used to detect calcium nodules in BMSCs.
RESULTS AND CONCLUSION: Compared with the model group, high-, middle -, and low-dose Erxian Decoction significantly increased the proliferative capacity of BMSCs in ovariectomized rats (P < 0.01), and significantly improved alkaline phosphatase activity in BMSCs of ovariectomized rats (P < 0.05, P < 0.0.1). The highest activity of alkaline phosphatase in BMSCs was found after treatment with middle-dose Erxian Decoction (P < 0.01). High- and middle-dose Erxian Decoction also promoted the formation of calcium nodules in BMSCs (P < 0.01). These results indicate that to improve BMSCs proliferation and osteogenic differentiation in ovariectomized rats is one of the intrinsic mechanisms of Erxian Decoction in the treatment of osteoporosis.
