Differentiation of pluripotent stem cells
First Claim
1. A method of increasing the yield of cells expressing markers characteristic of the definitive endoderm lineage by differentiating human pluripotent stem cells into cells expressing markers characteristic of the definitive endoderm lineage, the method comprising treating the human pluripotent stem cells with a medium lacking activin A, and containing GDF-8 and 14-Prop-2-en-1-yl-3,5,7,14,17,23,27-heptaazatetracyclo[19.3.1.1˜

Abstract
The present invention is directed to methods to differentiate pluripotent stem cells. In particular, the present invention is directed to methods and compositions to differentiate pluripotent stem cells into cells expressing markers characteristic of the definitive endoderm lineage comprising culturing the pluripotent stem cells in medium comprising a sufficient amount of GDF-8 to cause the differentiation of the pluripotent stem cells into cells expressing markers characteristic of the definitive endoderm lineage.
