摘要:

背景:现代研究表明骨碎补具有推迟细胞退行性变、降低骨关节病发病率的作用。

目的:比较不同剂量骨碎补冻干粉诱导兔骨髓间充质干细胞增殖、分化的效果,并筛选出最佳剂量。
方法:利用密度梯度离心法结合贴壁筛选法分离培养兔骨髓间充质干细胞,分为空白组、转化生长因子β1阳性对照组、骨碎补高、中、低剂量组(分别含骨碎补0.4 mg,0.1 mg,5 μg),取第3代骨髓间充质干细胞,根据实验分组加入不同培养液进行培养,1周后MTT比色法检测活细胞数目,免疫组化法测定Ⅱ型胶原表达。
结果与结论:MTT比色结果显示转化生长因子β1和骨碎补冻干粉均能促进骨髓间充质干细胞增殖,转化生长因子β1阳性对照组>骨碎补低剂量组>骨碎补中剂量组>骨碎补高剂量组>空白组。细胞免疫组化检测Ⅱ型胶原结果显示转化生长因子β1和骨碎补冻干粉均可以诱导兔骨髓间充质干细胞向软骨细胞分化,诱导后的细胞明显表达Ⅱ型胶原,转化生长因子β1阳性对照组>骨碎补低剂量组>骨碎补中剂量组>骨碎补高剂量组>空白组。结果表明骨碎补能促进兔骨髓间充质干细胞增殖和分化,尤以5 μg剂量效果最佳。

Abstract:

BACKGROUND: Modern research shows that Drynaria can delay cell degeneration and reduce the incidence of osteoarthritis.

OBJECTIVE: To observe the proliferation and differentiation of rabbit bone marrow mesenchymal stem cells induced by different dosages of Drynaria freeze-dried powder, and to explore the optimum induction concentration.
METHODS: Rabbit bone marrow mesenchymal stem cells were isolated and cultured in vitro by density gradient centrifugation and adherence screening methods, and then divided into blank group, positive control group (transforming growth factor β1), high-, middle-, low-dosage Drynaria groups (0.4 mg, 0.1 mg, 5 μg). Passage 3 cells were selected and cultured in different media. After 1 week, cell viability was detected by MTT method, and expression of type II collagen by immunohistochemical method.
RESULTS AND CONCLUSION: Both transforming growth factor β1 and Drynaria could improve the proliferation of bone marrow mesenchymal stem cells, and the increase in cell proliferation was ranked as follows: positive control group > low-dosage group > middle-dosage group > high-dosage group > blank group. Bone marrow mesenchymal stem cells were differentiated into chondrocytes under induction of transforming growth factor β1 and Drynaria, and induced cells significantly expressed type II collagen. The expression of type II collagen was ranked as follows: positive control group > low-dosage group > middle-dosage group > high-dosage group > blank group. These findings suggest that Drynaria can promote the proliferation and differentiation of rabbit bone marrow mesenchymal stem cells, and the optimal dosage is 5 μg.
