Abstract |
BACKGROUND:Transplantation of islets of Langerhans is regarded as a promising therapy for type 1 diabetes. A large number of β-cells are required for the treatment of human type 1 diabetes. Pluripotent stem cells, such as embryonic stem cells and induced pluripotent stem cells, have been considered as new sources for cell replacement therapy. METHODS:Cell aggregates were prepared from human iPS cells using agarose microwell plates and differentiated into pancreatic endocrine cells by changing the culture media with different additives. RESULTS:After 20days of culture, approximately 30% of cells in aggregates were positive for C-peptide. After another 14days in culture, the cells gained an ability to alter C-peptide release in response to changes in the glucose concentration. CONCLUSIONS:Uniform aggregates of human iPSCs were easily prepared on agarose microwell plates and efficiently differentiated into the pancreatic endocrine lineage. Thus, aggregate culture is a suitable method for preparing islet-like aggregates from human iPSCs. GENERAL SIGNIFICANCE:Our results indicate that the microwell plate is suitable for scaling up the preparation of pancreatic endocrine cells from human iPS cells in a robotic system. |
