DISCUSSION This paper reports the first use of HSV to enhance cationic lipid-DNA transfection. Nevertheless, the transfection efficiency of the current non-viral gene carriers still needs to be improved, especially as regards direct in vivo transfection. HSV should be advanta- geous for this purpose because the effi- ciency of virus infection is very high, Figure 5.

Transfection agents comprised of cationic lipid preparations are widely used to transfect cell lines in culture with specific recombinant complementary DNA molecules. Despite being easy to work with, the major limitation of cationic lipid-based transfection reagents has always been low transfection effi-ciency compared with electroporation and viral-mediated gene delivery. Chemical transfection methods are the most widely used methods in contemporary research and were the first to be used to introduce foreign genes into mammalian cells . Advantages of cationic lipid-mediated transfection include high efficiency, ability to transfect a wide range of cell types, reproducibility, low toxicity, and simplicity.
