ABSTRACT
AIM:
To investigate the use of therapy ultrasound to enhance nonviral gene delivery.METHODS:
Endothelial cells (EC) and vascular smooth muscle cells (VSMC) were cultured in 6-well plates. Plasmid (pcDNA3.1/His/LacZ) with or without microbubbles at the different concentrations was transfected into the cells with the use of ultrasound for 1 min at 2 MHz, 1.8 mechanical index (MI). Additional controls included ultrasound alone, microbubble alone and microbubble plus plasmid. The rate of blue cells and the activities of ?-Gal were measured. In addition, cell viability was detected with different time from 1 to 30 min of ultrasound irradiation and the different concentrations of microbubbles.RESULTS:
In the group of ultrasound with microbubble, the rate of blue cells and activity of ?-Gal markedly increased by 60% and 9-fold, respectively. Microbubbles at concentration of 10% led to the highest transfection effect. Ultrasoud exposure at 1 to 30 minute had no cell toxic effects, while microbubbles at the concentration of 50% had significant effect on cell survival.CONCLUSIONS:
Albumin-coated microbubbles markedly enhance gene delivery by therapeutic ultrasound-mediated microbubble destruction, which can be used as a safe and practicality vectors in gene therapy.
