(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) Activin and Wnt signaling are necessary and sufficient for mesendoderm (ME) differentiation of human embryonic stem cells (hESCs). In this study, we report that during the Activin and Wnt induced ME differentiation, Activin/Smad2 induces decrease of the repressive histone modification H3K27me3 by promoting proteasome-dependent degradation of EZH2. As a result, recruitment of the forkhead protein FOXH1 on open chromatin regions integrates the signals of Activin/Smad2 and Wnt/β-catenin to activate the expression of the ME genes including HAS2 and ALDH3A2. more...

(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) NANOG functions as the gateway for the generation of pluripotent stem cells (PSCs) in mice and humans. NANOG protein is highly expressed in pig pre-implantation embryos, indicating NANOG is a conserved pluripotency-associated factor. However, pig NANOG reporter PSCs have yet to be established, and the regulation of pluripotency by NANOG is not completely understood in this animal. In this study, pig NANOG tdTomato knock-in reporter PSCs were established using CRISPR/Cas9. more...

(Submitter supplied) We report genome-wide changes in chromatin state and transcriptional output following Wnt-priming and subsequent Activin induced differentiation of human embryonic stem cell and the effects of BET bromodomain inhibition during Wnt-priming. The two signals, Wnt and Activin, although provided sequentially, result in stable mesendoderm differentiation (Yoney et al., 2018).

(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) Digestive system development is orchestrated by combinatorial signaling interactions between endoderm and mesoderm, but how they are integrated in the genome is poorly understood. Here we identified the Xenopus foregut and hindgut progenitor transcriptomes, which are largely conserved with mammals. Using RNA-seq and ChIP-seq we show that BMP/Smad1 regulates dorsal-ventral gene expression in both the endoderm and mesoderm, whereas Wnt/b-catenin acts as a genome-wide toggle between foregut and hindgut programs. more...

(Submitter supplied) The TGF-β superfamily member Nodal triggers mesendoderm differentiation in embryonic stem (ES) cells. This transition however requires cooperating Wnt signaling inputs. Here we report that p53, a powerful tumor suppressor in adult tissues, orchestrates this cooperation. We show that p53, which is released from inhibition as mouse ES cells exit from pluripotency, acts as a direct inducer of Wnt3 expression. more...

(Submitter supplied) Human pluripotent stem cells (hPSCs) are an essential cell source in tissue engineering, studies of development, and disease modeling. Efficient and broadly amenable protocols for rapid lineage induction of hPSCs are of great interest in the stem cell biology field. We describe a simple yet robust method for differentiation of hPSCs into mesendoderm in defined conditions utilizing single-cell seeding and BMP4 and Activin A (BA) treatment. more...

(Submitter supplied) Activin/Nodal/TGF-β signaling pathway plays a major role in maintaining mouse epiblast stem cells (mEpiSCs). The mEpiSC medium which contains Activin A and bFGF induces differentiation of mouse embryonic stem cells (mESCs) to mEpiSC. Here we show that Activin A also has an ability to efficiently propagate mESCs without differentiation to mEpiSCs when combined with a MEK inhibitor PD0325901. mESCs cultured in Activin+PD retained high-level expression of naive pluripotency-related transcription factors. more...

(Submitter supplied) The combination of Wnt pathway activation by the GSK3 inhibitor and ERK pathway inhibition by the MEK inhibitor, which is known as 2i is a well-established method to maintain mouse embryonic stem cell (mESC) self-renewal. Here we show that Activin A also has the ability to promote naive pluripotency of mESCs when combined with the MEK inhibitor PD0325901. mESCs were efficiently propagated in a medium containing both Activin A and the MEK inhibitor (PD0325901). more...

(Submitter supplied) Human embryonic stem cells (HESCs) herald tremendous promise for the production of clinically useful cell types for the treatment of injury and disease. Numerous reports demonstrate their differentiation into definitive endoderm (DE) cells, the germ layer from which pancreatic β cells and hepatocytes arise, solely from exposure to a high dose of recombinant Activin/Nodal. Here, we show that combining a second related ligand, BMP4, in combination with Activin A yields 15 to 20% more DE as compared to Activin A alone. more...

(Submitter supplied) The processes of primitive streak formation and fate specification in the mammalian epiblast rely on complex interactions between morphogens and tissue organization. Little is known about how these instructive cues functionally interact to regulate gastrulation. We interrogated the interplay between tissue organization and morphogens by using human induced pluripotent stem cells (hiPSCs) down-regulated for the morphogen regulator GLYPICAN-4, in which defects in tight junctions result in areas of disrupted epithelial integrity. more...
