Differentiation of human embryonic stem cells
First Claim
1. A method for producing cells capable of glucose-stimulated insulin secretion from human pluripotent stem cells, comprising the steps of:
- a) culturing the human pluripotent stem cells,b) differentiating the human pluripotent stem cells into definitive endoderm cells by treating the human pluripotent stem cells with a medium supplemented with a TGF-β
receptor agonist,c) differentiating the definitive endoderm cells into pancreatic endoderm cells, andd) differentiating the pancreatic endoderm cells into pancreatic endocrine cells by treating the pancreatic endoderm cells with an inhibitor of TGF-β
R-1 kinase.

Abstract
The present invention provides methods to promote the differentiation of pluripotent stem cells and the products related to or resulting from such methods. In particular, the present invention provides an improved method for the formation of pancreatic hormone expressing cells and pancreatic hormone secreting cells. In addition, the present invention also provides methods to promote the differentiation of pluripotent stem cells without the use of a feeder cell layer and the products related to or resulting from such methods. The present invention also provides methods to promote glucose-stimulated insulin secretion in insulin-producing cells derived from pluripotent stem cells.
