Research Abstract

It is an important research subject to understand the mechanisms of pancreatic beta-cell development and maturation for the achievement of regeneration therapy for diabetes. The project yielded these three results: (1) To analyze the function of large Maf transcription factors in pancreatic endocrine cells, we generated floxed MafB mice. (2) To monitor the newly induced beta-like cells in mouse liver, we established the in vivo imaging system capable to quantify the insulin gene activity (3) Dominant role of MafA in the beta-like cell conversion in comparison with MafB.
