1. A method for obtaining human insulin secreting cells, comprisinga) culturing hES cells in a first medium comprising Activin A;
- andb) maturing the cells from a) in a second medium comprising nicotinamide;
thereby obtaining a population comprising human insulin secreting cells.

Abstract
This disclosure provides a system for producing pancreatic islet cells from embryonic stem cells. Differentiation is initiated towards endoderm cells, and focused using reagents that promote emergence of islet precursors and mature insulin-secreting cells. High quality populations of islet cells can be produced in commercial quantities for use in research, drug screening, or regenerative medicine.
