摘要
目的探讨IGF-1是否影响人牙周膜干细胞的成骨能力。方法分离、培养牙周膜干细胞,实验分为两组:对照组和实验组(经IGF-1诱导),进行矿化能力检测、实时定量RT-PCR检测、ALP活性检测。结果实验组人牙周膜干细胞体外矿化能力明显强于对照组。实验组人牙周膜干细胞Runx2,Collagen type I,Osteocalcin的表达以及ALP活性明显高于对照组。结论 IGF-1影响人牙周膜干细胞在体外的成骨能力。
Objective To investigate whether IGF-1 will impact the osteogenic potential of human periodontal ligament stem cells.Methods The periodontal ligament stem cells were isolated and cultured,and then divided into two groups: control group and experimental group(induced by IGF-1).Mineralization detection,real-time quantitative RT-PCR detection,and ALP activity detection were all conducted.Results In the experimental group,the vitro mineralization of human periodontal ligament stem cells was stronger than that in the control group.Besides,the expression of human periodontal ligament stem cells such as Runx2,Collagen type I,and Osteocalcintron as well as the ALP activity in the experimental group was significantly higher than that in the control group.Conclusion IGF-1 impacts the osteogenic potential of human periodontal ligament stem cells in vitro.
