Project description:In hemochorial placentation, trophoblast stem cells differentiate into multiple lineages to aquire specific functions, such as invasive and endocrine phenotype. FOSL1 has been identified as a key regulator for trophoblast differentiation. We used microarray to detail mechanisms underlying FOSL1 signaling pathway in trophoblast differentiation. 3 replicates of differentiated Rcho1 TS cells expressing control shRNA; 3 replicates of differentiated Rcho1 TS cells expressing Fosl1 shRNA

Project description:Trophoblast stem (TS) cell renewal and differentiation are essential processes in placentation. Here, we have identified the mechanism/targets of chromatin organizer/transcription factor called special AT-rich binding protein 1 (SATB1) action on TS cell renewal by RNA-seq analysis in Rcho-1 TS cells expressing Satb1 shRNAs.

Project description:Rcho-1 trophoblast stem cells can be maintained in a trophoblast stem cell state or induced to differentiate into trophoblast giant cells. During the differentiation process the PI3K pathway is constitutively activated. Microarray analysis of stem, differentiated and differentiated Rcho-1 trophoblast stem cells treated with the PI3K inhibitor LY294002.

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.

Project description:We had previously discovered that the transcription factor Cited2 was highly induced during trophoblast differentiation. In this study, we used an lentiviral shRNA strategy to decrease Cited2 expression in Rcho-1 trophoblast cells. A RNA-seq approach was used to determine global transcript differences inRcho-1 knockdown cells compared to control cells.

Project description:The placenta is constructed through the orchestration of trophoblast stem (TS) cell expansion and differentiation along a multi-lineage pathway. Dynamic regulation of histone H3K9 methylation is pivotal to cell differentiation for many cell lineages, but little is known about its involvement in trophoblast development. Among the twelve-known histone H3K9 methyltransferases, only SUV39H2 exhibited robust differential expression in stem versus differentiated rat TS cells. SUV39H2 transcript and protein expression were high in the stem state and rapidly declined as TS cells differentiated. Disruption of SUV39H2 expression in TS cells led to prominent phenotypic changes. Suv39h2-specific shRNA knockdown resulted in an arrest in TS cell proliferation and activation of trophoblast cell differentiation. These observations were reinforced by flow cytometry and transcript profiling. Histone H3K9 methylation status at specific loci exhibiting differentiation-dependent gene expression were regulated by SUV39H2 and also represented sites for SUV39H2 occupancy. Analyses of SUV39H2 on ex vivo rat blastocyst development supported its role in regulating TS cell expansion and differentiation. Finally, we identified SUV39H2 as a downstream target of CDX2, a master regulator of trophoblast lineage development. In summary, our findings indicate that SUV39H2 contributes to the maintenance of the TS cell stem state and restrains trophoblast cell differentiation and thus serves as a contributor to the epigenetic regulation of hemochorial placental development.

Project description:Expression profiling of wild-type and Prdm1 null mouse trophoblast giant cell cultures using Illumina whole genome mouse V2 arrays. The hypothesis tested was that Prdm1/Blimp1 regulates expression of genes required for spiral artery trophoblast giant cell function. Prdm1 null and littermate control wild-type trophoblast stem cell clones were generated from blastocyst outgrowths. Total RNA was obtained from multiple replicates of four wild-type TS cell clones and four Prdm1 null TS cell clones differenitated for zero, two, four and six days by growth factor withdrawal and hybridized to Illumina WG6_V2 arrays
