Abstract

目的 探讨葛根提取物(PLE)调节基质细胞衍生因子-1(SDF-1)对正畸静压力刺激大鼠牙周膜干细胞(PDLSCs)增殖和成骨分化的影响。 方法 从SD大鼠第一磨牙牙周膜组织中分离出PDLSCs,将第三代PDLSCs分为对照(NC)组(不做任何处理)、正畸静压力(OSP)组、PLE-L组(25 µg/mL PLE处理24 h)、PLE-H组(50 µg/mL PLE处理24 h)、AMD3100组(20 μmol/L SDF-1抑制剂AMD3100处理24 h)、PLE-H+AMD3100组(50 µg/mL PLE和20 μmol/L AMD3100共同处理24 h)。CCK-8法检测PDLSCs增殖;比色法检测碱性磷酸酶(ALP)活性;茜素红染色测定矿化结节形成;Western blot检测PDLSCs中增殖细胞核抗原(PCNA)、骨钙素(OCN)、骨桥蛋白(OPN)、RUNX家族转录因子2(Runx2)、SDF-1蛋白表达。 结果 与NC组比较,OSP组PDLSCs OD450值、ALP活性、矿化结节形成量、PCNA、OCN、OPN、Runx2、SDF-1的蛋白表达升高(P
