Patent Images
1. An in vitro method of producing human definitive endoderm cells that express SRY-box 17 (SOX17) and hepatocyte nuclear factor-3 beta (HNF3β
- ), the method comprising;
(a) culturing a population of human pluripotent stem cells; and
(b) differentiating the population of human pluripotent stem cells by culturing said population in a culture medium comprising equal to or less than 2%V/V serum and at least 30 ng/ml of activin A for a time sufficient to cause differentiation of said human pluripotent stem cells into human definitive endoderm cells expressing SOX17 and HNF3β
, thereby generating the human definitive endoderm cells expressing SOX17 and HNF3β
in said population.
