摘要: Background The molecular merger of latest-generation transduction technologies with advanced transgene control modalities may foster decisive advances in therapeutic reprogramming somatic cell phenotypes. Methods We have engineered self-inactivating HIV-1-based lentiviral expression vectors for reversible macrolide-adjustable expression. Results Lentiviral particles macrolide-responsive human vascular endothelial growth factor 121 (VEGF121) compared favourably isogenic streptogramin- and tetracycline-responsive configurations showed excellent growth-factor fine-tuning following into a variety mammalian lines different primary cells. Chicken embryos transduced macrolide-controlled VEGF121 production exhibited dose-dependent neovascularization exemplified lentivector-delivered transcription vivo. Conclusions Macrolide-adjustable lentivectors enable robust precise vitro vivo which give future gene therapy trials new impetus. Copyright © 2005 John Wiley & Sons, Ltd.
