摘要:

背景:实验证明胶原蛋白底物具有刺激成软骨的作用,但关于不同类型胶原蛋白刺激成软骨作用的能力仍存在争议。
目的:观察Ⅰ、Ⅱ型胶原蛋白对体外培养人软骨细胞生物学特性的影响。
方法:将P3代人软骨细胞分别加入普通培养板、Ⅰ型胶原蛋白包被培养板、Ⅱ型胶原蛋白包被培养板继续培养。培养10 d内,MTT法绘制细胞生长曲线;培养28 d后,采用ELISA法、聚合酶链反应、二甲基亚甲基蓝比色等方法检测3种培养板中软骨细胞分泌Ⅰ胶原蛋白、Ⅱ型胶原蛋白及糖胺多糖的量。
结果与结论:Ⅱ型胶原蛋白包被培养板中软骨细胞数量最多,增殖速度为Ⅰ型胶原蛋白包被培养板的2倍、普通培养板的5倍。Ⅱ型胶原蛋白包被培养板中软骨细胞分泌Ⅰ型胶原蛋白最少,与普通培养板板检测结果差异有显著性意义(P < 0.01),与Ⅰ型胶原蛋白包被培养板检测结果差异无显著性意义;Ⅱ型胶原蛋白包被培养板中软骨细胞分泌Ⅱ型胶原蛋白、糖胺多糖最多,与其他两种培养板检测结果差异有显著性意义(P< 0.01)。表明胶原蛋白包被培养板培养软骨细胞优于普通培养板,其中Ⅱ型胶原蛋白包被培养板在培养软骨细胞时更能维持细胞形态,延长去分化现象出现的时间,更利于细胞再分化。

Abstract:

BACKGROUND: Experiments have shown that the collagen substrate has the capability of stimulating cartilage generation, but the stimulating role of different types of collagen substrates remains controversial.
OBJECTIVE: To investigate the effect of type I and type II collagen on the biological characteristics of human chondrocytes cultured in vitro.
METHODS: Human chondrocytes at passage were cultured onto the ordinary culture plates (ordinary plate), type I collagen-coated culture plates (type I plate), and type II collagen-coated culture plates (type II plate). Cell growth curves were determined by MTT method after cells were cultured for 10 days. By ELISA, PCR, and 1,9-dimethyl methyleneblue technology, type I and type II collagen and glycosaminoglycan contents were quantitatively detected in cartilage cells 28 days after culture.
RESULTS AND CONCLUSION: The number of cartilage cells was the highest in type II plate, which was twice of that in type I plate and five times of that in ordinary plate. Cartilage cells in type II plate secreted the least amount of type I collagen, which showed significant differences compared with the ordinary plate (P < 0.01) and had no statistically significant difference with type I plate (P > 0.01). Cartilage cells in type II plate secreted the most amount of type II collagen and glycosaminoglycan, showing significant differences compared with the other two plates (P < 0.01). The cartilage cells cultured in collagen plates are better than that cultured in ordinary culture plate, type II collagen culture plate is better than type I collagen culture plate in maintaining cell shape, extending the dedifferentiation pattern, and promoting cell differentiation.
