ABSTRACT
Objective To investigate the effect of simvastatin on the mobilization and migration of endothelial progenitor cells(EPCs).Methods EPCs were harvested from the bone marrows of two rabbits,cultured with M199,and identified by immunohistochemistry.The identified EPCs were then treated with simvastatin with different concentrations(0,0.01,0.1,1.0 ?mol/L),and their migration induced by simvastatin was determined with Transwell chamber assay.Six rabbits models of cranial bone defect were established and divided into control and experiment groups(3 in each).In order to elicit the effects of simvastatin on mobilization of EPCs,simvastatin was embedded in polylactic acid compound,and implanted into the cranial bone defect area in the experiment group.Meanwhile,polylactic acid was implanted in the control animals.After 10 days,the expression rate of CD34+/CD133+ EPCs in the rabbit peripheral blood was counted by flow cytometry to determine the motivating effect of simvastatin.Results In Transwell experiment,16 hours after adding simvastatin(0,0.01,0.1 or 1.0 ?mol/L),the cell migration ability was obviously increased showing a dose-dependent trend(OD value0.077?0.014 in control group and 0.075?0.013 in 0.01 ?mol/L group vs 0.097?0.011 in 0.1 ?mol/L group and 0.099?0.019 in 1.0 ?mol/L group,P
