Forkhead box D3 (FOXD3) is a key transcription factor maintaining pluripotency in mouse embryonic stem cells (ESCs). Yet to date studies on its role in human ESCs are quite limited. In this study, we report that deletion of FOXD3 in human ESCs results in loss of pluripotency and spontaneous differentiation toward meso-endoderm. Ectopic overexpression of FOXD3 in hESCs leads to two different phenotypes: Human ESCs expressing high levels of FOXD3 undergo spontaneous meso-endoderm differentiation, whereas those with lower levels of FOXD3 maintain pluripotency. Next we deleted endogenous FOXD3 in the low ectopic expression model and find that addition of exogenous FOXD3 at a low level could rescue FOXD3-deficiency phenotype in hESCs. In summary, our findings suggest that FOXD3 dose-dependently regulates the balance of human ESCs between pluripotency and meso-endoderm fates, which adds to our understanding of the role of FOXD3 in humans.
