(Submitter supplied) We used circular micropattern cultures to differentiate human embryonic stem cells (H1 hESCs) into microcolonies termed ‘gastruloids’, comprising germ layer and extraembryonic cells. Differentiated gastruloids were dissociated and reseeded onto micropatterns in single cells solution to study cell sorting behaviors. We applied single-cell RNA sequencing to examine transcriptomes of gastruloids and reseeded cells.

(Submitter supplied) We applied BMP4 to circular micropattern cultures to differentiate human embryonic stem cells (H1 hESCs) into microcolonies termed ‘gastruloids’, comprising germ layer and extraembryonic cells. Time-course single cell RNA-sequencing was performed at 0h (immediately before BMP4 treatment), 12h, and 24h after BMP4 treatment. Combining these 0h, 12h, and 24h datasets with previously generated 44h datasets, we report transcriptomic dynamics over the course of BMP4-driven differentiation in micropatterned cultures.

(Submitter supplied) To determine the in vivo cellular identity of BMP-treated human embryonic stem cells (hESCs), we performed bulk RNA sequencing data of hESCs under pluripotency and BMP-treated conditions. Our analyses show that BMP-treated hESCs resemble human trophoblast cells in vivo.

(Submitter supplied) During gastrulation, epiblast cells are pluripotent and their fate is thought to be constrained principally by their position. Cell fate is progressively restricted by localised signalling cues from areas including the primitive streak (PS). However, it is unknown whether this restriction accompanies, at the single cell level, a reduction in potency. Investigation of these early transition events in vitro is possible via the use of Epiblast Stem Cells (EpiSCs), self-renewing pluripotent cell lines equivalent to the postimplantation epiblast. more...

(Submitter supplied) Anterior mesoderm (AM) and definitive endoderm (DE) progenitors represent the earliest embryonic cell types that are specified during germ layer formation at the primitive streak (PS) of the mouse embryo. Genetic experiments indicate that both lineages segregate from Eomes expressing progenitors in response to different NODAL signaling levels. However, the precise spatiotemporal pattern of the emergence of these cell types and molecular details of lineage segregation remain unexplored. more...

(Submitter supplied) The gastrulation process is controlled by the interplay between morphogenetic signals from BMP, WNT and NODAL pathways. Increasing evidences support an emerging role of the Hippo-YAP signaling in the cell-fate decisions that guide lineage specification in mouse and human Embryonic Stem Cells (hESCs). However, the contribution of YAP to the process of gastrulation in hESCs remains unknown. Here, we show that YAP1 regulates the specification, size and patterning of the three-germ layers. more...

(Submitter supplied) In hESCs, Wnt3/β-catenin activity is low and Activin/SMAD signaling ensures NANOG expression to sustain pluripotency. In response to exogenous Wnt3 effectors, Activin/SMADs switch to cooperate with β-catenin and induce mesendodermal differentiation genes. We show here that the HIPPO effector YAP binds to the WNT3 gene enhancer and prevents the gene from being induced by Activin in proliferating hESCs. more...

(Submitter supplied) As pluripotent human embryonic stem cells progress towards one germ layer fate, they lose the ability to adopt alternative fates. It is unknown how the cells’ competence for these alternative fates changes along their developmental trajectory or if this competence can be modulated. Here, we show that a differentiating stem cell’s probability of adopting a mesendodermal fate when given the appropriate signal falls sharply at a specific point along the ectodermal trajectory, and we further demonstrate that this point can be moved using genetic perturbations. more...

(Submitter supplied) Knowledge detailing human pre-gastrulation embryonic development including spatial self-organization and cell type ontogeny remains limited by available twodimensional technological platforms that do not recapitulate the in vivo condition. Here, we report a three-dimensional (3D) blastocyst-culture system, which enables human blastocyst development through primitive streak anlage (PSA) formation. These 3D-embryos mimic in vivo developmental landmarks and 3D-architectures, including embryonic disc, amnion, basement membrane, primary and primate unique secondary yolk sac, anterior-posterior polarity formation and PSA. more...

(Submitter supplied) The earliest aspects of human embryogenesis remain mysterious. To model patterning events in the human embryo we used colonies of human embryonic stem cells (hESCs) grown on micropatterned substrate and differentiated with BMP4. These recapitulate the embryonic arrangement of the mammalian germ layers and provide an assay to assess the structural and signaling mechanisms patterning the human gastrula. more...

Based on the distribution of key marker genes and their spatiotemporal expression patterns within the embryo, we identified 10 cell clusters corresponding to the epiblast and developing mesodermal populations. more...

(Submitter supplied) The germ cell lineage ensures reproduction, heredity and evolution. However, the mechanism for germ cell specification in primates, including humans, has been unknown. In primates, the pluripotent epiblast segregates the amnion upon implantation and thereafter initiates gastrulation to generate three germ layers. Here, we show that in cynomolgus monkeys, the SOX17/BLIMP1/TFAP2C-positive primordial germ cells (cyPGCs) arise from the dorsal amnion at embryonic day (E) 11. more...

(Submitter supplied) We reported H3K4me3, H3K27ac and H3K27me3 histone modification in EpiSCs and Nodal inhibited EpiSCs(EpiSCS/F). Using ChIP sequencing, we demonstrate that the active modification of H3K4me3 and H3K27ac level are higher in EpiSCS/F, suggesting EpiSCsS/F were in an active chromatin state. Interestingly, H3K27me3, the supressive modification enriched more in EpiSCS/F down regulated genes, suggesting H3K27me3 plays pivital roles in regulating gene expression.
