Methods: M-CSF-dependent bone marrow cells were isolated from 5-6 weeks old mice, and cultured in the presence of MCSF (25μg/L) with different concentrations of TNF-α(0, 1, 10, 100 μg/L) for 5 days, the formation of TRAP multinucleated cells was observed. These cells were also cultured in the presence of both RANKL (30 μg/L) and M-CSF (25 μg/L) with or without 10 μg/L TNF-α for4, 5, 6 and 9 days. The number of TRAP multinucleated cells and resorption pits on dentine slices were counted under light microscope.

AMs that collected, pured and cultured with contine method were stimulated by LPS of different concentration(0μg/ml,0.01μg/ml,0.1μg/ml,1μg/ml,10μg/ml) for 60min or by 1μg/ml LPS for different time stage (0min,5min,15min,30min,60min,120min) to observe the dynamic change of NF-кB intranuclear level and NO production, from which the best concentration and time point of LPS stimulation were selected. In the study, all AMs were divided into 4 groups: control group, group stimulated with LPS, group interrupted by Cal C and group inhibited by PDTC. The following parameters were measured: NF-кB level in nuclear protein extraction of AMs detected with sandwich ELISA, Inter-nuclear transposition of NF-кB observed with immunocytochemistry staining, NO content in cell culture medium quantitied with nitric acid reductase assay, Morphologic change of AMs in apoptosis observed with acridine orange staining and fragmentation at genome DNA of AMs detected with apoptotic electrophoresis assay.
