    Abstract: PROBLEM TO BE SOLVED: To identify markers which can be used to identify and/or segregate cells at their earliest stages of differentiation away from hESCs, in addition to achieving efficient directed differentiation of hESCs.SOLUTION: A method for producing human mesendoderm cells in vitro includes 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 to obtain a cell population comprising at least 5% of the human mesendoderm cells, wherein the expression of mRNA of a marker selected from the group consisting of brachyury, FGF4, and SNAI1 is greater than the expression of mRNA of a marker selected from the group consisting of SOX17 and SOX7.
