【摘要】:目的:体外研究改良富血小板血浆(modified platelet-rich plasma,mPRP)促进人乳牙牙髓干细胞成骨分化的作用。方法:以α-MEM作为基础培养基,分别加入1%、2%、5%、10%4种不同浓度mPRP或者10%胎牛血清(对照),对第4代SHED连续培养并诱导矿化,碱性磷酸酶试剂盒检测ALP活性的变化,qRT-PCR方法检测细胞内RUNX2和骨钙素mRNA含量的改变。结果:不同浓度的mPRP均可以促进乳牙牙髓干细胞的ALP活性,且浓度为2%时A值最高;qRT-PCR检测显示2%mPRP可以上调乳牙牙髓干细胞内RUNX2及骨钙素mRNA的含量。结论:一定浓度的mPRP对乳牙牙髓干细胞的成骨分化具有一定的促进作用。
[Abstract]:Aim: to study the effect of modified platelet-rich plasma (modified platelet-rich plasma,mPRP) on osteogenic differentiation of human deciduous dental pulp stem cells. Methods: using 伪-MEM as the basic medium, the fourth generation of SHED was continuously cultured and mineralized by adding 4 kinds of mPRP of different concentrations or 10% fetal bovine serum (control). The activity of ALP was detected by alkaline phosphatase kit and the changes of RUNX2 and osteocalcin mRNA were detected by qRT-PCR. Results: different concentrations of mPRP could promote the ALP activity of deciduous dental pulp stem cells, and the A value was the highest when the concentration was 2, and 2%mPRP could up-regulate the contents of RUNX2 and osteocalcin mRNA in deciduous dental pulp stem cells. Conclusion: mPRP at a certain concentration can promote osteogenic differentiation of deciduous dental pulp stem cells.
