1. A method of making a cell population enriched for endoderm cells comprising culturing embryonic stem cells in the absence of serum and the presence of activin and Wnt for about one to about six days, isolating brach+/HNF3β
- + cells, a culturing said isolated cells in the absence of serum and the presence of activin and an inhibitor of Wnt signalling for at least about one day.
