ABSTRACT
BACKGROUND:
Scutellaria baicalensis Georgi is a famous traditional Chinese medicine, which is widely used in treating fever, upper respiratory tract infection and other diseases. Pharmacology study showed it can exhibit anti-bacterial, anti-inflammation and analgesic effects. In this study, we investigated the effect of baicalin on the odonto/osteogenic differentiation of inflammatory dental pulp stem cells (iDPSCs). METHODS ANDRESULTS:
iDPSCs were isolated from the inflamed pulps collected from pulpitis. The proliferation of iDPSCs was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2,5-tetrazolium bromide (MTT) assay and flow cytometry. Alkaline phosphatase (ALP) activity assay, alizarin red staining, Real-time reverse transcription-polymerase chain reaction (RT-PCR) and Western blot assay were conducted to examine the differentiation potency along with the involvement of nuclear factor kappa B(NF-κB) and ß-catenin/Wnt signaling pathway. MTT assay and cell-cycle analysis demonstrated that baicalin had no influence on the proliferation of iDPSCs. ALP activity assay and alizarin red staining demonstrated that baicalin could obviously enhance ALP activity and calcified nodules formed in iDPSCs. RT-PCR and Western blot showed that the odonto/osteogenic markers were upregulated in baicalin-treated iDPSCs. Moreover, expression of cytoplastic phosphor-P65, nuclear P65, and ß-catenin in iDPSCs was significantly increased compared with DPSCs, but the expression in baicalin-treated iDPSCs was inhibited. In addition, 20 µM Baicalin could accelerate odonto/osteogenic differentiation of iDPSCs via inhibition of NF-κB and ß-catenin/Wnt signaling pathways.CONCLUSION:
Baicalin can promote odonto/osteogenic differentiation of iDPSCs through inhibition of NF-κB and ß-catenin/Wnt pathways, thus providing direct evidence that baicalin may be effective in repairing pulp with early irreversible pulpitis.Palabras clave
