Gene Therapy for the Treatment of Malignant Brain Tumors with <i>In Vivo</i> Tumor Transduction with the Herpes Simplex Thymidine Kinase Gene/Ganciclovir System. Iowa Methodist Medical Center, Des Moines, Iowa

Abstract

Murine retroviral vectors can infect a wide variety of proliferating mammalian cell types (e.g. lymphocytes). Non-proliferating tissues (e.g. neurons) are not transduced by murine retroviral vectors. These findings suggest that this type of vector may be useful for the selective introduction of genes into growing tumors in the brain, since the tumor is essentially the only tissue that will integrate and express the vector genes.
