Abstract

Background: The unfolded protein response (UPR) influences cellular differentiation and function.

Results: UPR-inducing agents enhance the differentiation of definitive endoderm cells from mouse ESCs. Inhibition of the UPR prevents the specific differentiation.

Conclusion: The UPR is required for the formation of definitive endoderm cells.

Significance: This study identifies a new molecular mechanism that interconnects the UPR and cell fate decisions in early embryonic development.
