(Submitter supplied) This study is the first characterization of the first trimester placenta transcriptome, highlighting similarities and differences among the sexes in ongoing human pregnancies resulting in live births. Sexual dimorphism may contribute to pregnancy outcomes, including fetal growth and birth weight, which was seen in our cohort, with males significantly heavier than females at birth. This transcriptome provides a basis for development of early diagnostic tests of placental function that can indicate overall pregnancy heath, fetal-maternal health, and long term adult health.

(Submitter supplied) Human placenta bulk mRNA-sequencing from n=124 first trimester (59 female, 65 male) and n=43 third trimester (18 female, 25 male) tissue samples. A subset of 23 pregnancies has matched placenta tissue collected at both first and third trimester. Tissue was collected at Cedars-Sinai Medical Center in Los Angeles, California, USA. First trimester placenta was collected at gestational ages of 70-100 days from leftover tissue from chorionic villus sampling for prenatal genetic diagnosis, after cleaning to remove maternal decidua. more...

(Submitter supplied) The first trimester is a critical window of maternal-fetal communication for pregnancy. RNA-sequencing of matched maternal decidua (4) and placenta (4) identified 91 sexually dimorphic receptor-ligand pairs across the maternal-fetal interface, 32 in females and 59 in males.

(Submitter supplied) The first trimester is a critical window of maternal-fetal communication for pregnancy. Using single cell RNA-sequencing to dissect placenta heterogeneity, we identified five major cell types (trophoblasts, stromal cells, hofbauer cells, antigen presenting cells and endothelial cells). We identified seven unique trophoblast subclusters, including new subtypes that transition into the terminal cell types, extra-villous trophoblasts and syncytiotrophoblasts. more...

(Submitter supplied) Here, we examine sex-specific gene expression differences during in vitro differentiation of male and female human embryonic stem cells (hESCs) into trophoblastic progenitors, as our current understanding of the early events of human trophoblast formation is limited. We perform RNA-Sequencing in 3 female and 3 male hESC lines at days 0 and 5 of BMP4/A/P trophoblastic progenitor cell differentiation. more...

(Submitter supplied) Background: The placenta is vital for fetal development and its contributions to various developmental issues, such as pregnancy complications, fetal growth restriction, and maternal exposure, have been extensively studied in mice. Contrary to popular belief, the placenta forms mainly from fetal tissue; therefore, it has the same biological sex as the fetus it supports. However, while placental function is linked to increased risks of pregnancy complications and neurodevelopmental diseases in male offspring in particular, the sex-specific epigenetic (e.g., DNA methylation) and transcriptomic features of the late-gestation mouse placenta remain largely unknown.Methods: We collected male and female mouse placentas at late gestation (E18.5, n = 3/sex) and performed next-generation sequencing to identify genome-wide sex-specific differences in transcription and DNA methylation. more...

(Submitter supplied) As susceptibility to many adult disorders originates in utero, we here hypothesized that fetal sex influences gene expression in placental cells and produces functional differences in human placentas. We found that fetal sex differentially affects gene expression in a cell-phenotype dependent manner among all four placental cell-phenotypes studied: cytotrophoblasts, syncytiotrophoblasts, arterial endothelial cells and venous endothelial cells. more...

(Submitter supplied) During pregnancy, the placenta ensures multiple functions, which are directly involved in the initiation, fetal growth and outcome of gestation. The placental tissue involved in maternal-fetal exchanges and in synthesis of pregnancy hormones is the mononucleated villous cytotrophoblast (VCT) which aggregates and fuses to form and renew the syncytiotrophoblast (ST). Knowledge of the gene expression pattern specific to this endocrine and exchanges tissue of human placenta is of major importance to understand functions of this heterogeneous and complex tissue. more...

(Submitter supplied) Previously, we have examined the effect of maternal dietary n-3 LCPUFA supplementation during pregnancy to reduce offspring obesity risk. Considering the involvement of the placenta in fetal programming, we here analyzed the sexually dimorphic potential of placental gene expression, its response to the n-3 LCPUFA intervention and their correlation to offspring obesity risk. The placenta is implicated to play a key role in mediating fetal /metabolic programming of the offspring in utero. more...

(Submitter supplied) Physiological oxygen tension rises dramatically in the placenta between 8 and 14 weeks of gestation. Abnormalities in this period can lead to gestational diseases, whose underlying mechanisms remain unclear. We explored the changes at mRNA level by comparing the transcriptomes of human placentas at 8-10 gestational weeks and 12-14 gestational weeks. A total of 20 samples were collected and divided equally into four groups based on sex and age. more...

(Submitter supplied) Overnutrition during pregnancy influences the future health of the offspring, with outcomes differing depending on the child’s sex. The placenta is involved in the programming of obesity, type 2 diabetes and cardiovascular disease. Sex-specific adaptation of the placenta may be central to the differences in fetal growth and survival. The impact of diet and fetal sex on placental gene expression and epigenetic marks was investigated in mice fed a high-fat (HFD) or a control diet (CD), during the first 15 days of gestation Microarrays analysis revealed that expression was affected by maternal diet and was sexually dimorphic.
