Monkey embryonic stem (ES) cells share similar characteristics to human ES cells and provide a primate model of allotransplantation, which allows to validate efficacy and safety of cell transplantation therapy in regenerative medicine. Bone morphogenetic protein 4 (BMP4) is known to promote trophoblast differentiation in human ES cells in contrast to mouse ES cells where BMP4 synergistically maintains self-renewal with leukemia inhibitory factor (LIF), which represents a significant difference in signal transduction of self-renewal and differentiation between murine and human ES cells. As the similarity of the differentiation mechanism between monkey and human ES cells is of critical importance for their use as a primate model system, we investigated whether BMP4 induces trophoblast differentiation in monkey ES cells. Interestingly, BMP4 did not induce trophoblast differentiation, but instead induced primitive endoderm differentiation. Prominent downregulation of Sox2, which plays a pivotal role not only in pluripotency but also placenta development, was observed in cells treated with BMP4. In addition, upregulation of Hand1, Cdx2, and chorionic gonadotropin beta (CG-beta), which are markers of trophoblast, was not observed. In contrast, BMP4 induced significant upregulation of Gata6, Gata4, and LamininB1, suggesting differentiation into the primitive endoderm, visceral endoderm, and parietal endoderm, respectively. The threshold of BMP4 activity was estimated as about 10 ng/mL. These findings suggest that BMP4 induced differentiation into the primitive endoderm lineage but not into trophoblast in monkey ES cells.
