Arid3a is required for mammalian placenta development

ABSTRACT: Previous studies in the mouse indicated that Arid3a plays a critical role in the first cell fate decision required for generation of trophectoderm (TE). Here, we demonstrate that Arid3a is widely expressed during mouse and human placentation and essential for early embryonic viability. Arid3a is located within trophoblast giant cells and other trophoblast-derived cell subtypes in the junctional and labyrinth zones of the placenta. Conventional Arid3a knockout embryos suffer restricted intrauterine growth with sever defects in placental structural organization. Arid3a null placentas show aberrant expression of subtype-specific markers as well as significant alteration in inflammatory response-related genes, cytokines and chemokines. We provide evidence that BMP4-mediated induction of trophoblast stem (TS)-like cells from human induced pluripotent (iPS) stem cells results in ARID3A upregulation and cytoplasmic to nuclear translocation. Overexpression of ARID3A in human iPS and BMP4-mediated TS-like cells up-regulated TE markers, whereas pluripotent markers were down-regulated. Our results indicate that the roles of Arid3a are conserved and essential for mammalian placental development through regulation of both intrinsic and extrinsic developmental programs.

Arid3a modulates the first cell fate decision by direct regulation of both embryonic and extraembryonic gene expression (ChIP-Seq)

Project description:Arid3a, a transcription factor known for its requirement in B-lymphocyte development, has been recently identified as a member of ES cell pluripotency network. Arid3a is moderately expressed in ES cells, and its expression is gradually increased during differentiation. Since Arid3a shows the highest expression in placenta, we hypothesized that Arid3a may play important roles in TE development. We report that Arid3a is a central regulator of both TE-specific and pluripotency-associated gene expression during ES cell differentiation. While dispensable for self-renewal, we observed that knockdown of Arid3a delays differentiation of ES cells. Induction of Arid3a leads ES cells to promote differentiation, specifically towards TE lineage. Moreover, these Arid3a-overexpressing cells maintained in TE culture media are sufficient to generate functional trophoblast stem-like cells, suggesting roles of Arid3a in TE differentiation. By integrative analyses using the chromosomal targets of Arid3a with expression profiling, we revealed the dual roles of Arid3a, as a direct activator of TE-specific genes and a repressor of pluripotency-associated genes. We further revealed the repressive roles of Arid3a are mediated by histone deacetylases (HDACs). Taken together, our results demonstrate that Arid3a is a critical novel regulator in TE lineage specification. Arid3a ChIP was performed using bioChIP-sequencing. Control ChIP-sequencing was performed using BirA cells. HDAC1 ChIP was performed as native antibody ChIP-sequencing.

Specification of HiPS to in vivo placental cell types

Project description:Here we identify conditions that efficiently drive specification of primed induced pluripotent stem cells to trophectoderm, named Trophoblast Stem Cell (TS). iPS-derived-TS cells share transcriptional, morphological and functional characteristics with human ex vivo cytotrophoblasts including transcriptional activation of human endogenous retroviruses, expression of COVID-19 associated host factors and the ability to generate multinucleated syncytiotrophoblasts with a large fusion index. At high densities in 5% O2, iPS-derived-TS cells form villi-like structures and express extravillous and syncytiotrophoblast proteins HCG-β, HLA-G. To define the molecular changes associated with specification, we compare temporal single cell RNAseq analysis under three separate conditions: 1) BMP4, 2) BMP4 and inhibition of Wnt, 3) Trophoblast Stem cell condition (TS) activation of EGF and Wnt, inhibition of TGFbeta, HDAC and ROCK signaling.

Fosl1 transdifferentiate embryonic stem cells to differentiated trophoblast stem cells (RNA-seq)

Project description:During mammalian embryonic development, the first lineage commitment event gives rise to two distinct cell populations: the trophectoderm (TE) and the inner cell mass (ICM). The TE consists of outer cells of the blastocyst and ultimately forms the placenta while the ICM gives rise to all the embryonic tissues. Numerous transcription factors (TFs) guiding ICM differentiation into different embryonic tissues have been characterized. However, only a few TFs that are required for TE specification and differentiation have been identified, and much less is understood as to how these TFs interact with other TFs or with their chromosomal targets in order to drive cell fate towards TE lineage. Understanding trophectoderm development is crucial because cells in this lineage are required for proper embryo implantation in the uterus. Defects in this lineage can cause early failure of pregnancy as well as other pregnancy related disorders such as preeclampsia and intrauterine growth restriction (IUGR). Here, we characterize the function of one of TE-specific TF, Fosl1, which was previously suggested as having some role in placental development. We utilized mouse embryonic stem (ES) cells (derived from ICM) and showed that ectopic expression of Fosl1 can transdifferentiate ES cells to differentiated TS cells (trophoblast giant-like cells). We show that Fosl1 does so by directly binding and activating TE specific genes and genes associated with epithelial-mesenchymal transition (EMT). Using mouse trophoblast stem (TS) cells, we also establish that Fosl1 is required for specification of TS cells to trophoblast giant cells (TGCs) subtype. Therefore, we postulate that Fosl1 is a key regulator of TS cell differentiation.

Direct Conversion of Trophoblast Stem Cells into Pluripotent Stem Cells by Oct4

Project description:Embryonic stem (ES) cells and trophoblast stem (TS) cells are both derived from early embryos, yet these cells have distinct differentiation properties. ES cells can differentiate into all three germ layer cell types, whereas TS cells can only differentiate into placental cells. It has not been determined whether TS cells can be converted into ES-like pluripotent stem (PS) cells. Here we report that overexpression of a single transcription factor, Oct4, in TS cells is sufficient to convert TS cells into a pluripotent state. These Oct4 induced pluripotent stem (OiPS) cells have the epigenetic characteristics of ES cells, including X chromosome reactivation and elevated H3K27 me3 modifications. The gene expression profile of OiPS cells and ES cells was very similar. Moreover, OiPS cells can differentiate into the three germ layer cell types in vitro and in vivo. More importantly, chimeric mice with germline transmission could be efficiently produced from OiPS cells. To our knowledge, this is the first evidence showing that only one single transcription factor could convert the non-embryonic TS cells into pluripotent stem cells with pluripotency. Gene expression profile of iPS cells and trophoblast stem cells were generated by Affymetrix Mouse Gene 1.0 ST Array. The Gene expression profile of ES cell R1 in GSE17004 was used as control. Three biological repeats were included for each line.
