ABSTRACT
Objective:
To observe the effect of static magnetic fields(SMF) on the proliferation of bone mesenchymal stem cells(MSC) in human.Methods:
The MSC were obtained by using gradient centrifuge method, and then selected by the adhesive method. The third generation cells were irradiated by use of static magnetic fields at different intensities for 5 days(8 h/d). The method of MTT was employed to evaluate the level of proliferation. The parameters regarding the variation of the cell cycle were detected with the flow cytometry(FCM).Results:
As compared to the control group, the proliferative rate of the MSC exposed to 0.05 mT SMF was significantly higher; there was no difference between the 0.10 mT group and control group; howere, cell proliferation was attenuated significantly when SMF intensity was 0.50 mT and 1.00 mT. No abnormal ploidy was found in any group.Conclusion:
The effect of SMF on the proliferation of MSC is dependent on the magnetic intensity. 0.05 mT SMF can accerate the proliferation of MSC. 0.10 mT SMF have no effects on the growth of MSC. Wherease, 0.50 mT and 1.00 mT SMF can attenuate the growth of MSC.
