However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.
