Abstract: Objective To explore the cause of bisphosphate-related osteonecrosis by studying the effect of pamidronate disodium (PD) on osteogenic differentiation in jaw bone marrow mesenchymal stem cells (JBMMSCs). Methods JBMMSCs were isolated from the human jaw bone. The concentrations of PD suitable for the growth of JBMMSCs and subsequent studies were screened by thiazolyl blue (MTT) assay at concentrations of 0, 0.1, 0.5, 1.0, 5.0 and 10 μg/ml; The quantification of alizarin red S (ARS) staining and alkaline phosphatase (ALP) staining, and quantitative polymerase chain reaction (qRT-PCR) were used to compare the osteogenic ability of JBMMSCs at different concentrations of PD. Results MTT assay showed that 0.1 and 0.5 μg/ml PD did not affect the growth of JBMMSCs (P>0.05), while 1.0, 5.0 and 10 μg/ mL PD significantly inhibited the growth of JBMMSCs (P<0.05). The quantification of ARS staining and ALP staining, and qPCR showed that the osteogenic ability of JBMMSCs at 0.5 and 0.75 μg/ml of PD was significantly lower than that in the control group (P<0.05). ARS staining and qPCR showed similar osteogenic ability of JBMMSCs treated by 0, 0.1, 0.2, 0.3 or 0.4 μg/ml PD (P>0.05). Conclusion PD may induce osteonecrosis by inhibiting the osteogenic differentiation of JBMMSCs when over a threshold of dose.
