Hydrosoluble polymers for muscular gene delivery

This review is focusing on the characteristics of the striated muscle tissue with regards to features possibly affecting gene transfer, as well as the different soluble polymers that have been evaluated as gene carriers. The described formulations are ranging from polymers displaying a high density of positive charges to non-ionic molecules. Nevertheless, polymers exhibiting few or no positive charges appear to our opinion as the most promising approach to achieve both safe and efficient transfection of the striated muscles.
