Preprimitive streak and mesendoderm cells
First Claim

1. An in vitro method of producing mesendoderm cells, the method comprising the steps of:
- (a) obtaining a cell population comprising human pluripotent stem cells;
(b) providing the human pluripotent stem cells with at least one TGFβ
superfamily growth factor in an amount sufficient to promote differentiation of the human pluripotent stem cells to mesendoderm cells, said mesendoderm cells being multipotent cells that can differentiate into mesoderm or definitive endoderm cells; and
(c) allowing sufficient time for the mesendoderm cells to form, wherein the sufficient time for the mesendoderm cells to form has been determined by detecting the presence of mesendoderm cells in the cell population.
