Research Abstract

We introduced Pdx1 and Ngn3 into regenerative liver using non-viral gene transfer technique. Co-expression of Pdx1 and Ngn3 activated the transcription of various islet-related genes, and induced insulin synthesis in the liver. Futhermore, it was suggested that this reprogramming was enhanced by co-expression of triple factors adding v-maf musculoaponeurotic fibrosarcoma oncogene family, protein A (MafA).In conclusion, the reprogramming will occur even in vivo without the need for viral vectors. Further investigation might be needed to optimize the combination of transgene.
