ABSTRACT
Objective:To compare the osteogenic differentiation of dental pulp stem cells(DPSCs)induced by osteopontin(OPN)and mineralizing culture medium(MCM).Methods:DPSCs were cultured with OPN(OPN group)and MCM(MCM group)respectively. The morphology of the DPSCs were observed under inverted microscope.The mineralize nodules were observed by alizarin red staining. RT-RCR was used to detect the mRNA expression of bone sialoprotein (BSP),Runt-related transcription factor 2(Runx-2),osteocal-cin(OCN)and collagen-1(Col-1).Results:Similar number of mineralized nodules was found in the 2 groups(P >0.05)after 28 day culture.The mRNA expression level of BSP gene in OPN group was higher than that in MCMgroup(0.864 ±0.112 and 0.514 ±0.068, P 0.05).Conclusion:The capabilities of OPN and MCMin inducing osteogenic differentiation of DPSCs are similar.
