Title
Live cell image for ESCs (human primed embryonic stem cells) into GATA3-expressing cells
Description
Live imaging of the GATA3-knockin KhES-1 cells treated with AP for 72 h. AP treatment is addition of the two inhibitors for the ACTIVIN/NODAL and FGF signaling. Recording was started immediately after AP addition. G2-4 DIC.tif is images for bright field, and G2-4 Red.tif is images for red fluorescence (The fluorescence of tandem tomato). The fluorescence indicates GATA3-expressing cells. Timestamp is attached on the images.

(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.(MeSH Terms)
