ObjectiveThis study aimed to evaluate the vascular endothelial growth factor (VEGF) expression and permeability of vascular endothelial cell under microvibration.Methods Human umbilical vein endothelial cell (HUVEC) were cultured, randomly vibrated under low frequency of 0.2, 0.5, 2, 5 Hz, 30 min per day. The VEGF mRNA level was detected by Tagman probe real-time fluorescence quantitative polymerase chain reaction (PCR), and the VEGF protein expression level was detected by Western blot. The permeability of vascular endothelial cell was evaluated.Results Compared with the blank control group, the mRNA and protein expression level of VEGF were significantly increased under 0.2, 0.5 Hz microvibration (PPPPConclusion0.2-0.5 Hz microvibration can up-regulate the expression of VEGF mRNA and protein in vascular endo- thelial, and increase the permeability.
