Modified platelet-rich plasma promotes the osteogenic differentiation of stem cells from human exfoliated deciduous teeth / 实用口腔医学杂志

ABSTRACT

Objective:To investigate the effect of modified plateletrich plasma(mPRP)on the osteogenic differentiation of stemcells from human exfoliated deciduous teeth(SHED).Methods:mPRP at 1%,2%,5%,10% and FBS at 10% were added to thecultured SHED of passage 4,respectively.The influence of mPRP on alkaline phosphatase(ALP)activity was evaluated using ALPkit.RUNX2 and osteocalcin mRNA expression in the treated cells were examined by realtime PCR.Results:mPRP enhanced ALPactivity in the SHED,and the effect of mPRP was more obvious at 2%.Treatment of the cells with 2% mPRP upregulated the mRNAexpressions of RUNX2 and osteocalcin.Conclusion:mPRP can promote the osteogenic differentiation of SHED.
