Here we show that as human embryonic stem (ES) cells exit the pluripotent state, NANOG can play a key role in determining lineage outcome. It has previously been reported that BMPs induce differentiation of human ES cells into extraembryonic lineages. Here we find that FGF2, acting through the MEK-ERK pathway, switches BMP4 induced human ES cell differentiation outcome to mesendoderm, characterized by the uniform expression of T (brachyury) and other primitive streak markers. We also find that MEK-ERK signaling prolongs NANOG expression during BMP-induced differentiation; that forced NANOG expression results in FGF independent BMP4 induction of mesendoderm; and that knockdown of NANOG greatly reduces T induction. Together, our results demonstrate that FGF2 signaling switches the outcome of BMP4 induced differentiation of human ES cells by maintaining NANOG levels through the MEKERK pathway.
