(Submitter supplied) Objective: Amniotic fluid (AF) is a proximal fluid to the fetus containing higher amounts of cell-free fetal RNA/DNA than maternal serum, thereby making it a promising source for novel biomarker discovery of fetal development and maturation. Our aim was to compare AF transcriptomic profiles at different time points in pregnancy to demonstrate unique genetic signatures that would serve as potential biomarkers indicative of fetal maturation. more...

(Submitter supplied) Amniotic fluid (AF) is a complex biological material that provides a unique window into the developing human. Residual AF supernatant contains cell-free fetal RNA. The objective of this study was to develop an understanding of the AF core transcriptome by identifying the transcripts ubiquitously present in the AF supernatant of euploid midtrimester fetuses. We detected 476 well-annotated genes present in all twelve AF samples. more...

(Submitter supplied) The second trimester fetal transcriptome can be assessed based on cell-free RNA found within the amniotic fluid supernatant. The objective of this study was to compare the suitability of two technologies for profiling the human fetal transcriptome: RNA-Seq and expression microarray. Comparisons were based on total numbers of gene detected, rank-order gene expression, and functional genomic analysis. more...

(Submitter supplied) The objective of this study was to identify the tissue expression patterns and biological pathways enriched in term amniotic fluid cell-free fetal RNA by comparing functional genomic analyses of term and second-trimester amniotic fluid supernatants. There were 2,871 significantly differentially regulated genes. In term amniotic fluid, tissue expression analysis showed enrichment of salivary gland, tracheal, and renal transcripts as compared with brain and embryonic neural cells in the second trimester. more...

(Submitter supplied) The placenta is a dynamic organ which undergoes extensive remodeling throughout pregnancy to support, protect and nourish the developing fetus. Despite the importance of the placenta, very little is known about its gene expression beyond very early pregnancy and post-partum. Therefore, we utilized RNA-sequencing to characterize the transcriptome from the fetal (chorioallantois) and maternal (endometrium) components of the placenta from mares throughout gestation (4, 6, 10, 11 m). more...

(Submitter supplied) Amniotic fluid is critical for the development of foetus, which provides the appropriate conditions for foetus growth. Besides its presumed traditional roles of providing movement place and protecting from crushing, amniotic fluid is considered to have more important roles in the nervous development of foetus respecting nervous related compositions and close contact with the skin of foetus. Peripheral nervous sensory system is the feeling basis for the body with neuritis anchoring on the surface of skin. more...

(Submitter supplied) The placental renin-angiotensin system (RAS) is important for placentation. RAS expression is greatest in early gestation. This may be due (in part) to suppression of miRNAs that target the placental RAS, but this has never been explored. In this study, human placental miRNAs were measured at 10–11 (early), 14–18 (mid), and 38–40 (term) weeks gestation, as well as in placentae from women with early- or late-onset preeclampsia (n=4/group), using an Agilent miRNA microarray (V19). more...

(Submitter supplied) Background: Turner syndrome, a common sex chromosome aneuploidy, has characteristics and malformations associated with the phenotype. Fetal amniotic fluid is a complex biological material that could contribute to the understanding Turner syndrome pathogenesis. Global gene expression analysis of Turner syndrome fetal amniotic fluid supernatant was utilized to identify organ systems and specific genes that may play a role in the pathophysiologic changes that are seen in individuals with Turner syndrome. 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) 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) To describe normal cardiac and brain development during late first and early second trimester in human fetuses using microarray and pathways analysis and the creation of a corresponding “normal” database. RNA from recovered tissues was used for transcriptome analysis with Affymetrix 1.0 ST microarray chip. From the amassed data we investigated differences in cardiac and brain development within the 10-18 GA period dividing the sample by GA in three groups: 10-12 (H1), 13-15(H2) and 16-18(H3) weeks. more...

(Submitter supplied) Maturation of lung cell types occurs during late gestation to ensure lung function and optimal gas exchange at birth. The pulmonary lymphatic endothelium is an understudied cell type and is essential for immune regulation and interstitial fluid removal. Here we provide the first characterization of the pulmonary lymphatic endothelium during late gestation prior to birth. We used microarrays to detail the global transcriptional programme underlying maturation of pulmonary lymphatic endothelium and identified 1,281 genes with significant changes in gene expression over time. more...
