Mesoderm and definitive endoderm cell populations
First Claim
1. A method of making a cell population enriched for hepatocytes comprising the steps of (a) culturing pluripotent stem cells in the presence of activin to induce differentiation into endoderm lineages, (b) further culturing the cells of step (a) in the presence of BMP-4 and bFGF and in the absence of serum to induce differentiation into a hepatic lineage, and (c) culturing the cells from step (b) with one or more cytokines that promote hepatocyte growth to produce a population enriched for hepatocytes.

Abstract
The present invention provides cell populations that are enriched for mesendoderm and mesoderm, and cell populations that are enriched for endoderm. The cell populations of the invention are useful for generating cells for cell replacement therapy. The present invention further provides a method of generating hepatocytes, cell populations enriched for hepatocytes, and a method of hepatocyte replacement therapy.
