| 摘 要： | 目的: 观察脂多糖模拟的炎症微环境对体外培养的人牙周膜成纤维细胞（periodontal ligament cells, PDLCs）增殖与成骨分化的影响。方法: 体外培养鉴定人牙周膜成纤维细胞,分别用浓度为0、0.1、10 μg/mL脂多糖作用于细胞,采用MTT法观察脂多糖对PDLCs增殖的影响,运用实时定量PCR和Western印迹法检测脂多糖模拟的炎症微环境对PDLCs成骨分化的影响。采用SPSS 13.0软件包对数据进行统计学分析。结果: 0.1 μg/mL脂多糖促进PDLCs增殖,增强成骨标志物mRNA和蛋白的表达;10 μg/mL脂多糖可抑制PDLCs的增殖及碱性磷酸酶、RUNX2、Ⅰ型胶原、骨形态发生蛋白2的表达,其结果有统计学意义。结论: 高浓度脂多糖（10 μg/mL）模拟的炎症微环境对PDLCs增殖及成骨分化有抑制作用,低浓度脂多糖（0.1 μg/mL）对PDLCs的增殖和成骨分化有促进作用。

| Abstract: | PURPOSE: To investigate the effects of inflammatory microenvironment on proliferation and osteogenic differentiation of periodontal ligament cells(PDLCs) in vitro. METHODS: Human PDLCs were isolated and characterized. MTT was used to investigate the proliferation rate of PDLCs under different concentration of lipopolysaccharide（LPS）. The PDLCs' osteogenic differentiation was investigated using real-time PCR and Western blot. The date were statistically analyzed with SPSS 13.0 software package. RESULTS: Treatment with 0.1 μg/mL LPS increased proliferation of PDLCs and enhanced the expression of osteogenic gene and protein. The proliferation of PDLCs and expression of alkaline phosphatase(ALP), RUNX2, Collagen-I, BMP2 were significantly decreased by 10 μg/mL LPS. CONCLUSIONS: The inflammatory microenvironment (10 μg/mL LPS) inhibits the proliferation and osteogenic differentiation of human PDLCs. |
