摘要
目的:探讨硅酸二钙离子浸提液对人牙周膜细胞增殖与矿化能力的影响。方法:组织块消化法分离培养人牙周膜细胞,制备硅酸二钙离子浸提液,并配置为条件培养基诱导培养细胞,采用细胞增殖-毒性检测试剂盒检测细胞增殖情况,检测碱性磷酸酶活性及矿化结节形成情况。结果:硅酸二钙离子浸提液对人牙周膜细胞无细胞毒性,促进细胞增殖,可有效提高细胞的碱性磷酸酶活性,与对照组比较差异具有统计学意义(P<0.05)。该条件培养基可显著促进牙周膜细胞形成矿化颗粒,与对照组比较差异具有统计学意义(P<0.05)。结论:硅酸二钙离子浸提液对人牙周膜细胞无细胞毒性,促进了人牙周膜细胞的增殖和矿化能力。
Objective:To investigated the effect of ionic products of dicalcium silicate on human periodontal ligament cells proliferation and mineralization. Methods: Human periodontal ligament cells were isolated and cultured by enzymolytic method. Ionic products of dicalcium silicate was prepared as previously reported. The cells were co-cluture with ionic products of dicalcium silicate or with normal DMEM. Then CCK-8,Alkaline Phosphatase(ALP) analyses and mineralization assay were used to identify the cell proliferation and mineralization effects. Results: The induced cells showed high cell proliferation rate, higher ALP activity(P<0.05) and increased calcified nodules formation(P<0.05).Conclusion:Ionic products of dicalcium silicate promote human periodontal ligament cell proliferation and mineralization capacity.
