Project description:This SuperSeries is composed of the following subset Series:; GSE11220: Timecourse of developing mouse placenta, with placental and decidual tissues profiled separately; GSE11222: Placental and decidual timecourse samples normalized and modeled with an undissected e17 sample Experiment Overall Design: Refer to individual Series

Project description:We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). For these samples, at each stage the fetal placenta and maternal decidual tissues were dissected and profiled separately (See series 1). For this experiment (Series 2), placental and decidual timecourse samples were normalized and modeled with two undissected (including placental and decidual tissue) e17 placentas to allow for scaling of values for comparison to the undissected placenta samples used in the publicly available mouse GeneAtlas dataset Keywords: time course

For all dissected samples, fetal placenta and maternal decidual tissues were dissected and pooled separately for each litter prior to RNA extraction and hybridization on Affymetrix microarrays.

Project description:The placenta is an abundant source of mesenchymal stem/stromal cells (MSC). Although presumed of translationally-advantageous fetal origin, the literature instead suggests a high incidence of either contaminating or pure maternal MSC. Despite definitional criteria that MSC are CD34ÌÛ, increasing evi- dence suggests that fetal MSC may be CD34 positive in vivo. We flow sorted term placental digests based on CD34Ì_ expression and exploited differential culture media to isolate separately pure fetal and maternal MSC populations. This method has considerable translational implications, in particular to clinical trials underway with ÛÏplacentalÛ MSC of uncertain or decidual origin.

Project description:The human placenta, a transient endocrine organ, is vital for successful pregnancy and fetal health, which undergoes dynamic cellular and functional changes during gestation. However, systematic longitudinal analysis of in utero human placenta formation and development across the lifespan is not feasible due to ethical and technical limit. To circumvent those difficulties and reveal the dynamic placentation, we obtain transcriptional snapshots of 217404 single cells from cynomolgus monkey placenta, decidua and embryo tissues spanning ten consecutive but distinct developmental stages across pregnancy. We reveal the development-related changes in the compositions of placental trophoblasts, mesenchymal cells and endothelial cells in different pregnant stage. We pinpoint that the placenta mesenchymal cells are derived from a special extra-embryonic mesoderm. Particularly, we describe the relationship between the embryonic primitive hematopoiesis and the placental endothelial cells, Hofbauer cells and erythrocytes. Besides, we found the cell types and their transcriptome compositions in decidual tissues show insignificant changes during the gestation. Finally, cell-cell interactions between trophoblasts and decidual cells, and between different cell types on villi are performed and suggested the mechanisms in dynamic placentation. Together, the high-resolution atlas we constructed would serve as a valuable resource to extrapolate key events for studies on human placentation and its associated disorders.

Project description:A Toxoplasma gondii infection during pregnancy can result in spontaneous abortion, preterm labor, or congenital fetal defects. The decidual immune system plays a critical role in regulating the immune micro-environment and in the induction of immune tolerance. To better understand the factors that mediate the decidual immune response associated with the T. gondii infection, a large-scale study employing TMT proteomics was conducted to characterize the differential decidual immune proteomes from infected and uninfected human decidual immune cells samples. The decidual immune cells from 105 human voluntary abortion tissues were purified, and of the 5510 unique proteins identified, 181 proteins were found to be differentially abundant (>1.2-fold cutoff, P＜0.05) in the T. gondii-infected decidual immune cells. 11 proteins of 181 differentially expressed proteins associated with trophoblast invasion, placental development, intrauterine fetal growth, and immune tolerance were verified using a quantitative real-time polymerase chain reaction and western blotting. This systematic research identified a broad range of immune factors in human decidual immune cells, shedding a new insight into the decidual immune molecular mechanism for abnormal pregnancy outcomes associated with T. gondii infection.

Project description:Ribosome profiling and mass spectrometry have revealed thousands of previously unannotated small and alternative open reading frames (sm/alt-ORFs) that are translated into micro-/alt-proteins in mammalian cells. However, their prevalence across human tissues and biological roles remain largely unexplored. The placenta is an ideal model for identifying unannotated microproteins and alt-proteins due to its considerable protein diversity that is required to sustain fetal development during pregnancy. Here, we profiled unannotated microproteins and alt-proteins in human placenta tissues from preeclampsia patients or healthy individuals by mass spectrometry, identified 66 unannotated microproteins or alt-proteins, and validated the expression of five microproteins biochemically. We further demonstrated that one microprotein, XRCC6P1, associates with translation initiation complex eIF3, and negatively regulates translation. Thus, we revealed a hidden sm/alt-ORF-encoded proteome in the human placenta, which may advance the mechanism studies for placenta development, as well as placental disorders such as preeclampsia.
