Title
Time-lapse images of syncytium formation from ESCs (human primed embryonic stem cells)
Description
To monitor syncytium formation, two lines of ESC that were marked with different fluorescent proteins (H2B-Venus and mCherry, respectively) were independently treated with AP for 4 days, and then mixed and cocultured. After 4–6 days of coculture, the appearance of syncytia, defined as cells expressing both the Venus signals in the nucleus and mCherry signals in the cell body, was detected.

(Abstract) Human primed embryonic stem cells (ESCs) are known to be converted to cells with several trophoblast properties, but it has remained controversial whether this phenomenon represents the inherent differentiation competence of human primed ESCs to trophoblast lineages. In this study, we report that chemical blockage of ACTIVIN/NODAL and FGF signals is sufficient to steer human primed ESCs into GATA3-expressing cells that give rise to placental hormone-producing syncytia analogous to syncytiotrophoblasts of the post-implantation stage of the human embryo. Despite their cytological similarity to syncytiotrophoblasts, these syncytia arise from the non-trophoblastic differentiation trajectory that recapitulates amniogenesis. These results provide insights into the possible extraembryonic differentiation pathway that is unique in primate embryogenesis.
