摘要
目的:观察乳铁蛋白(lactoferrin,LF)对体外培养的人牙周膜细胞(HPDLCs)增殖、迁移和成骨分化的影响。方法:原代培养并鉴定人牙周膜细胞,稳定传代后用MTT比色法、Transwell法及划痕试验检测浓度分别为0、10、20μg/ml的乳铁蛋白对牙周膜细胞增殖和迁移的影响;矿化条件下,0、10、20μg/ml的乳铁蛋白作用牙周膜细胞后,茜素红染色法和实时荧光定量PCR检测矿化能力及成骨相关基因的表达。结果:10、20μg/ml乳铁蛋白均能促进HPDLCs增殖、迁移(P<0.05)。10、20μg/ml乳铁蛋白组矿化结节数量增多(P<0.05),碱性磷酸酶(ALP)、骨钙蛋白(OCN)、骨桥蛋白(OPN)表达量均有升高(P<0.05)。结论:乳铁蛋白能够促进人牙周膜细胞增殖、迁移与成骨分化。
Objective: To observe the effects of lactoferrin( LF) on the proliferation,migration and osteogenic differentiation of human periodontal ligament cells( HPDLCs) in vitro. Methods: HPDLCs were cultured and identified. The proliferation and migration of HPDLCs cultured with 0,10 and 20 μg / ml lactoferrin respectively were tested by MTT assay,Transwell assay and scratch test. The osteogenic differentiation of the cells was evaluated using alizarin red staining and real-time PCR. Results: Lactoferrin at 10 and 20μg /ml increased the proliferation( P〈0. 05),increased the quantities of mineralized nodules and the expression of alkaline phosphatase( ALP),osteocalcin( OCN) and osteopontin( OPN)( P〈0. 05). Conclusion: Lactoferrin promotes the proliferation,migration and osteogenic differentiation of HPDLCs.
