Abstract: Definitive endoderm differentiation is crucial for generating respiratory and gastrointestinal organs including pancreas and liver. However, whether epigenetic regulation contributes to this process is unknown. Here, we show that the H3K27me3 demethylases KDM6A and KDM6B play an important role in endoderm differentiation from human ESCs. Knockdown of KDM6A or KDM6B impairs endoderm differentiation, which can be rescued by sequential treatment with WNT agonist and antagonist. KDM6A and KDM6B contribute to the activation of WNT3 and DKK1 at diffe...
