1. A method of producing definitive endoderm cells comprising:
- a) culturing pluripotent stem cells in the presence of trichostatin A (TSA), with the proviso that activin A is not present; and
b) thereafter, culturing the pluripotent stem cells in the absence of TSA, and in a media comprising activin Athereby producing definitive endoderm cells.

Abstract
The present invention provides a method of generating definitive endoderm, mesoderm, or ectoderm cells. The method includes culturing embryonic stem cells, parthenogenetic cells, or induced pluripotent stem cells in the presence of a demethylation agent, a histone deacetylase inhibitor, or a combination thereof, and thereafter, culturing the stem cells in the absence of the agent or combination of agents, to produce definitive endoderm cells, mesoderm, or ectoderm cells.
