With the aim of developing successful human gene therapy, numerous viral and nonviral (synthetic) methods of gene transfer have been developed (1,2), each method having limitations as well as advantages. To develop in vivo gene transfer vectors with high efficiency and low toxicity, several groups have attempted to overcome the limitations of one vector by combining them with the strengths of another.
