Research Abstract

To utilize siRNA technology to the treatment of HPV-related diseases, developing an efficient siRNA delivery system is essential. In this study, we established organotypic raft cultures using TERT- and HPV16-E6E7 immortalized human keratinocytes stably expressing firefly luciferase. These cultures facilitated quantitative analysis of knock-down efficiency induced by local siRNA delivery and showed that some cationic liposomes could deliver siRNA through stratified squamous epithelium.
