Ultrasound-assisted microbubbles gene transfer in tendons for gene therapy

Résumé

Our study aimed at evaluating the use of ultrasound-assisted microbubbles gene transfer in mice Achilles tendons. Using a plasmid encoding luciferase gene, it was found that an efficient and stable gene expression for more than two weeks was obtained when tendons were injected with 10 mu g of plasmid in the presence of 5 x 10(5) BR14 microbubbles with the following acoustic parameters: 1 MHz, 200 kPa, 40% duty cycle and 10 min of exposure time. The rate of gene expression was 100-fold higher than that obtained with naked plasmid injected alone without ultrasound or with ultrasound in absence of microbubbles. The long term expression of transgene makes ultrasound-assisted microbubble a suitable method for gene therapy in tendons.
