Development of Safer Gene Delivery Systems to Minimize the Risk of Insertional Mutagenesis-Related Malignancies: A Critical Issue for the Field of Gene Therapy

Figure 6

This figure shows a comparison between gamma-retroviridae- and self-inactivating-retroviridae-derived vector systems. The polyA signal is a more efficient transcription termination signal in the gamma-retroviridae-derived vector than in the self-inactivating variant.
