Objective:To construct Lenti-SM22alpha-p27-EGFP recombinant lentiviral vectors targeting vascular smooth muscle cells(VSMCs) and to investigate the impact on VSMCs proliferation by cell cycle analysis. Methods: Recombinant lentiviruses were constructed. The viruses were transfected into VSMCs and vascular endothelial cells(VECs). Results: SM22α-p27 lentiviruses exhibited effective and specific inhibition on VSMCs. SM22α promoter targeted p27 was able to be selectively over-expressed in VSMCs and to inhibit proliferation by cell cycle arrest at G0/G1. Conclusion: Recombinant lentiviruses driven by SM22α promoter could selectively infect VSMCs, thus lead to p27 protein over-expression and G0/G1 arrest.
