The mechanisms controlling self-renewal versus lineage commitment in human embryonic stem (hES) cells are not well understood. Nonetheless, current knowledge suggests a crucial role for TGFbeta signaling in controlling these early fate decisions. We have investigated the effects of TGFbeta pathway activation and inhibition on gene expression in hES cells. Our data reveal that SMAD 2/3 signaling directly supports NANOG expression, while SMAD 1/5/8 activation moderately represses SOX2. In addition  ...[more]
