an orthotopic bladder tumor model and the evaluation of intravesical sarna treatment

Apresentamos um novo método para o tratamento de cancro da bexiga com intravesical entregue pequena activador RNA (sarna) em um xenoenxerto modelo de rato ortotópico tumor da bexiga. O modelo do rato é estabelecido por cateterismo uretral sob anestesia geral inalatória. Queimadura química é então introduzido para a mucosa da bexiga usando solução de nitrato de prata intravesical para romper a camada de glicosaminoglicano bexiga e permite que as células para anexar. Após várias lavagens com água estéril, cancro da bexiga humana KU-7-luc2-GFP células são instilado através do cateter no interior da bexiga para habitar durante 2 horas. Subsequente crescimento de tumores de bexiga é confirmada e monitorado por ultra-som na bexiga vivo e de imagem de bioluminescência. Os tumores são então tratados com intravesical sarna formulados em nanopartículas de lípidos (LNPs). O crescimento do tumor é monitorizado com ultra-sons e bioluminescência. Todos os passos do presente processo são demonstradas no vídeo que o acompanha.
