(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) 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) 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) 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) 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...

(Submitter supplied) Bone morphogenetic protein (BMP) signaling is known to support differentiation of human embryonic stem cells (hESCs) into mesoderm and extraembryonic lineages, whereas other signaling pathways can largely influence this lineage specification. Here, we set out to reinvestigate the influence of ACTIVIN/NODAL and fibroblast growth factor (FGF) pathways on the lineage choices made by hESCs during BMP4-driven differentiation. more...

(Submitter supplied) The mesodermal precursor populations for different internal organ systems are specified during gastrulation by the combined activity of extracellular signaling systems such as BMP, Wnt, Nodal, and FGF. The BMP, Wnt and Nodal signaling requirements for the differentiation of specific mesoderm subtypes in mammals have been mapped in detail, but which mesodermal cell types depend on FGF signaling is not precisely known. more...

(Submitter supplied) Here we describe an approach to generate gastruloids that have a more complete antero-posterior development. We used bioengineered hydrogel microwell arrays to promote the robust derivation of mouse ESCs into post-implantation epiblast-like (EPI) aggregates in a reproducible and scalable manner. These EPI aggregates break symmetry and axially elongate without external chemical stimulation. Inhibition of WNT signaling in early stages of development leads to the formation of gastruloids with anterior neural tissues.

(Submitter supplied) The anterior-posterior axis of the mammalian embryo is laid down by the anterior visceral endoderm (AVE), an extraembryonic signaling center that is specified within the visceral endoderm. Current models posit that AVE differentiation is promoted globally by epiblast-derived Nodal signals, and spatially restricted by a BMP gradient established by the extraembryonic ectoderm. Here, we report spatially restricted AVE differentiation in bilayered embryo-like aggregates made from mouse embryonic stem cells that lack an extraembryonic ectoderm. 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) Single cell technologies hold promise for resolving complex early developmental phenotypes. Here we define a novel Hedgehog (Hh)-Fibroblast Growth Factor (FGF) signaling axis for the formation of anterior mesoderm lineages during gastrulation. Single-cell transcriptome analysis of Hh-deficient mesoderm revealed selective deficits in anterior mesoderm populations—culminating in defects to anterior embryonic structures including the pharyngeal arches, heart, and anterior somites. more...

(Submitter supplied) It has now become clear that the process of fate specification during early embryogenesis is mediated by a handful of key signaling pathways. However, how the temporal and spatial integration of these signals plays out to give rise to self-organization of tissues remains obscure. Here we use artificial human gastruloids and quantitative single-cell analysis to dissect the temporal integration of two key pathways WNT and ACTIVIN that along with BMP control gastrulation and primitive streak patterning in model systems. more...

(Submitter supplied) Pyruvate is a key metabolite in glycolysis and tricarboxylic acid (TCA) cycle. Exogenous pyruvate modulates metabolism, provides cellular protection, and is essential for the maintenance of human preimplantation embryos and human embryonic stem cells (hESCs). However, little is known about how pyruvate contributes to cell fate determination during epiblast stage. In this study, we used hESCs as a model to demonstrate that elevated exogenous pyruvate shifts metabolic balance towards oxidative phosphorylation in both maintenance and differentiation conditions. more...

(Submitter supplied) Exostosin 1 (Ext1) is a glycosyltransferase involved in the biosynthesis of the extracellular matrix Heparan Sulfate Proteoglycan (HSPG). Knockdown of Ext1 caused gastrulation defects and formation of an abnormal body axis. Since ext1 has been implicated as an indirect contributor to multiple signaling pathways in vertebrate development, microarray was used to identify genes expressed in gastrulae that would be affected by a reduction in ext1 expression. more...

(Submitter supplied) Members of the transforming growth factor (TGF)-β superfamily play essential roles in the pluripotency, self-renewal, and differentiation of embryonic stem cells. While bone morphogenic proteins maintain pluripotency of undifferentiated mouse ES cells, the role of Activin/Nodal signaling is less clear. To determine the target genes of Activin/Nodal-Smad2 signaling in undifferentiated embryonic stem cells, changes in gene expression were examined following stimulation with recombinant Activin (2 hours) or after inhibition of Activin/Nodal with SB431542 (24 hours) using defined media culture conditions with LIF and 20 ng/mL BMP4. more...

(Submitter supplied) Nonsense-mediated RNA decay (NMD) is a highly conserved pathway that selectively degrades specific subsets of RNA transcripts. Here, we provide evidence that NMD regulates early human developmental cell fate. We found that NMD factors tend to be expressed at higher levels in human pluripotent cells than differentiated cells, raising the possibility that NMD must be downregulated to permit differentiation. more...

(Submitter supplied) XEN cells are derived from the primitive endoderm of mouse blastocysts. In culture and in chimeras they exhibit properties of parietal endoderm. However, BMP signaling promotes XEN cells to form an epithelium and differentiate into visceral endoderm (VE). Of the several different subtypes of VE described, BMP induces a subtype that is most similar to the VE adjacent to the trophoblast-derived extraembryonic ectoderm. more...
