| Outline of Final Research Achievements |
The human induced pluripotent stem cells are potential resource for type 1 diabetes cell based therapies. Although,the beta cell differentiation had been deeply investigated, the molecular mechanism of differentiation of beta cell from hiPSCs and in which levels were achieved the beta cell derived hiPSCs has not been understood completely. In this study we provide, a single cell transcriptome of differentiated beta cells from hiPSCs, in which double labelled with Venus and mCherry proteins (hIveNry). The Venus protein could express under INS promoter and mCherry under NGN3 promoter, meaning that by fluorescent protein could monitor from NGN3+ red endocrine progenitor to the Venus positive beta cells. In this study we performed the cell profiling of the fluorescent positive cells viewing the status of the differentiation of the beta cells in which the maturation process was confirmed by glucose responsivity.
