RESUMO

Objective To observe the effects of green fluorescence protein mediated by lentivirus in bladder, and to de?termine the amount of virus obtained good transfection effects. Methods lentivirus carring GFP gene was perfused using transurethral approach into bladder of guinea pigs. Samples of bladder, liver, kidney and lungs were collected for frozen sec?tions after feeding seven days. The distribution of green fluorescence was observed using laser confocal microscopy. Re?sults The titer of lentivirus was 4 × 108. GFP was found under the mucosa when the amount of lentivirus transurethral was 30μL. GFP was distributed widely in muscle layer using 40μL lentivirus. GFP was detected even stronger in muscle layer when the amount was 50μL. GFP was found in muscle layer when 25μL lentivirus was injected intravenously. GFP was not found in other tissues than in bladder via transurethral perfusion. There was higher GFP in liver, lungs and other organs than in bladder via intravenous injection. Conclusion Lentivirus can mediate GFP transfecting bladder of guinea pig successful?ly and escape the distribution of GFP all over the body intravenously, which will bring new research direction and method for clinical treatment of diseases in bladder.
