The rise of new genetic technologies and their implied power has engendered concerns among religious, scientific, and civic leaders that these new technologies may be growing more rapidly than our ability to prudently control and productively use them. The ability to insert human genes into human patients to treat specific genetic diseases is known as human gene therapy–has been one of the concerns noted by those observing the evolution of genetic technologies. Advances in biotechnology have brought gene therapy to the forefront of medical research. The prelude to successful gene therapy i.e. the efficient transfer and expression of a variety of human gene into target cells has already been accomplished in several systems.
