Project
Title
Z-stack images of the KhES-1 colonies treated or untreated with AP for 2 days
Description
Z-stack images of expression of E-cadherin and F-actin. After AP treatment, morphological changes suggestive of a transition from columnar to squamous epithelium, an anatomical feature distinguishing amniotic ectoderm from the epiblast, were observed. AP treatment is addition of the two inhibitors for the ACTIVIN/NODAL and FGF signaling.

Published in 2022 Jun 21

(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.
