GENERATION OF HUMAN PLURIPOTENT STEM CELL DERIVED FUNCTIONAL BETA CELLS SHOWING A GLUCOSE-DEPENDENT MITOCHONDRIAL RESPIRATION AND TWO-PHASE INSULIN SECRETION RESPONSE
The invention provides for methods of differentiating pancreatic endocrine cells into pancreatic beta cells expressing PDX1, NKX6.1, MAFA, UCN3 and SLC2A. These pancreatic beta cells may be obtained by step-wise differentiation of pluripotent stem cells. The pancreatic beta cells exhibit glucose-dependent mitochondrial respiration and glucose-stimulated insulin secretion similar to islet cells.
