Human primed and naïve PSCs are equally potent in differentiating into bona fide trophoblast stem cells (ATAC-Seq)

ABSTRACT: Cells of the trophoblast lineage constitute the major part of placental tissues in higher mammals. Recent derivation of human trophoblast stem cells (TSC) from placental cytotrophoblasts (CT) and from blastocyst opens new opportunities for studying development and function of human placenta. Here we report that inhibition of TGF pathway leads to direct and robust conversion of primed human pluripotent stem cells into TSC. The resulting cell lines exhibit self-renewal, are able to differentiate into the main trophoblast lineages, and present RNA and epigenetic profiles that are indistinguishable from the TSC lines derived from placenta or blastocyst. Furthermore, activation of YAP pathway is necessary and sufficient for this conversion.

Activation of the interferon pathway in trophoblast cells infected with SARS-CoV-2

Project description:Infection with SARS-CoV-2 in pregnancy has been associated with poor maternal and neonatal outcomes and placental defects. The placenta, which acts as a physical and immunological barrier at the maternal/fetal interface, is not established until the end of the first trimester. Therefore, localized viral infection of the trophoblast compartment early in gestation could trigger an inflammatory response resulting in altered placental function and consequent suboptimal conditions for fetal growth and development. In this study, we investigated the effect of SARS-CoV-2 infection in early gestation placentae using placenta-derived human trophoblast stem cells (TSC), a novel in vitro model, and their extra-villous trophoblast (EVT) and syncytiotrophoblast (STB) derivatives. Consistent with host viral entry protein expression, SARS-CoV-2 was able to productively replicate in TSC-derived STB and EVT but not undifferentiated TSC. Both early EVT and STB elicited an interferon-mediated innate immune response similar to other cells infected with this virus. Therefore, we have also shown that placenta derived TSCs are a robust in vitro model to investigate the effect of this viral infection in the trophoblast compartment of the early placenta. Overall, these results suggest that SARS-CoV-2 infection in early gestation can adversely affect placental development and that might occur via directly infecting the differentiated trophoblast compartment, thus posing a higher risk for poor pregnancy outcomes.

Esrrb plays an important role in maintaining self-renewal of trophoblast stem cells (TSCs) and reprogramming somatic cells to induced TSCs [RNA-Seq]

Project description:Trophoblast stem cells (TSCs) are derived from the trophoectoderm of a blastocyst and can maintain self-renewal in vitro. Meanwhile, essential insights into the molecular mechanisms controlling placental developmental could be gained by using TSCs that can differentiate into the various placental trophoblast cell types in vitro. Esrrb is a transcription factor with pivotal roles in maintaining TSCs’ self-renewal, but the exact transcriptional networks that Esrrb involved in TSCs are largely unknown. In the present study, we elucidated the function of Esrrb during TSC self-renewal and differentiation. We demonstrate that precise levels of Essrb are critical for TSCs stemness maintenance and normal trophoblast differentiation, as Esrrb depletion results in down-regulation of the key TSC-specific transcription factors, consequently causing TSCs differentiation and forced expression of Esrrb can partially block TSCs differentiation in the absence of FGF4. This function of Esrrb is exerted by directly binding and activating a core set of TSC-specific target genes including Cdx2, Eomes, Sox2, Fgfr4 and BMP4. Furthermore, we investigate the role of Esrrb in reprogramming of mouse embryonic fibroblasts (MEFs) to induced TSCs (iTSCs). We show that Esrrb can facilitate the conversion of iTSCs from MEFs. Moreover, Esrrb can substitute for Eomes during this conversion process. Our findings provide a better understanding of the molecular mechanism of Esrrb in maintaining TSCs self-renewal and iTSCs reprogramming.

Naïve human embryonic stem cells can give rise to cells with trophoblast-like transcriptome and methylome [Bisulfite-Seq]

Project description:Human embryonic stem cells (hESCs) readily differentiate to somatic or germ lineages but have impaired ability to form extra-embryonic lineages such as placenta or yolk sac. Here we demonstrate that hESCs cultured in naïve media conditions can be converted into cells that exhibit the cellular and molecular phenotypes of human trophoblast stem cells (hTSCs) derived from human placenta or blastocyst. The resulting “transdifferentiated” hTSCs show reactivation of core placental genes, acquisition of a placenta-like methylome, and the ability to differentiate to extravillous trophoblasts and syncytiotrophoblasts. Modest differences are observed between transdifferentiated and placental hTSCs, most notably in the expression of certain imprinted loci. These results indicate that naïve hESCs can differentiate to extra-embryonic lineage, and demonstrate a new way of modeling human trophoblast specification and placental methylome establishment.

Transcriptomic profile of human placenta derived trophoblast organoid cultures with its tissue of origin, human placental villi.

Project description:The aim of this microarray experiment was to compare the overall transcriptomic profile of human placenta derived trophoblast organoid cultures with its tissue of origin, human placental villi. As the placental villi contains both trophoblast and stromal populations, we have included placenta derived stromal cultures in this comparison.
