This is for safety and convenience. The lining of the sinuses is similar to that of the lungs, but the site is smaller and more accessible. Genetic research is advancing steadily and sometimes rapidly on many fronts. Discoveries in genetics have led to novel strategies for treating diseases. The bottom line in any kind of biomedical research lies in the realm of treatment and prevention.
Ethics Debate For somatic cell gene therapy there seems to be a lot of support.
Somatic cell gene therapy represents a logical extension of existing treatments. For example somatic cells, such as bone marrow cells, involve changes limited to the cells of the person being treated. Germ line gene therapy, where genetic changes would be passed on deliberately to future generation, have caused more of a debate. Leroy Walters, director of the Center for bioethics at Georgetown University, explains that there would be two basic rationales for using germ line gene therapy to treat genetic diseases. One would be if some genetic diseases were resistant to somatic gene therapy.
