Project description:Transcriptomic profiling is a crucial tool for understanding growth, development, behavior and predisposition to diseases and the development of health biomarkers. Here, we demonstrate the feasibility of transcriptomic assessment of cell-free fetal RNA in vervet monkey amniotic fluid supernatant (AFS).

Project description:Intra-amniotic infection, the invasion of microbes into the amniotic cavity resulting in an inflammatory process, is a clinical condition that can lead to adverse pregnancy outcomes for the mother and fetus as well as severe long-term neonatal morbidities. Despite much research focused on the consequences of intra-amniotic infection, there is still little knowledge about the functional roles of innate immune cells that respond to invading microbes. In the current study, we performed RNA sequencing of sorted neutrophils and monocytes/macrophages from amniotic fluid from women with intra-amniotic infection to determine the transcriptomic differences between these innate immune cells. Further, we sought to identify specific transcriptomic pathways that were significantly altered by the maternal or fetal origin of amniotic fluid neutrophils and monocytes, the presence of a severe fetal inflammatory response, and pregnancy outcome (i.e. preterm or term delivery). We showed that significant transcriptomic differences exist between amniotic fluid neutrophils and monocytes/macrophages from women with intra-amniotic infection that are indicative of the distinct roles these cells play. We also found that amniotic fluid monocytes/macrophages of fetal origin display impaired ability to clear out microbes invading the amniotic cavity compared to those of maternal origin. Notably, we demonstrate that the transcriptomic changes in amniotic fluid monocytes/macrophages are heavily associated with the severity of the fetal inflammatory response, suggesting that the trafficking of fetal neutrophils throughout the umbilical cord is partially modulated by monocytes/macrophages in the amniotic cavity. Finally, we show that amniotic fluid neutrophils and monocytes/macrophages from preterm deliveries display enhanced transcriptomic activity compared to those from term deliveries, highlighting the protective role of these innate immune cells in this vulnerable period. Collectively, these findings demonstrate the underlying complexity of local innate immune responses in women with intra-amniotic infection, and provide new insights into the functions of amniotic fluid neutrophils and monocytes in the amniotic cavity.

Project description:Elucidating the developmental patterns of gene expression across brain regions is a critical step toward understanding brain development and disease. We previously studied the transcriptome of multiple brain regions and peripheral tissues across development in the vervet monkey, and identified transcripts related to hippocampal size in 59 animals across 10 developmental timepoints, ranging between 7 days to 9 years of age. Here, we extended this analysis with a focus on transcriptomic changes in hippocampus across early development in vervet neonates and infants under 1 year of age. We combined this dataset with the previously analyzed data. We identified groups of transcripts with age-related patterns, which correlated well with existing human resources. Additionally, expression quantitative trait locus (eQTL) analysis identified two further genes, RAB31 and CHMP1B, associated with hippocampal volume, refining the previously identified locus. This dataset provides unique developmental expression data in the hippocampus of a non-human primate, and expands our catalog of local and distant eQTL in this brain region.

Project description:We have discovered that GBS significantly remodels its transcriptome in response to exposure to human amniotic fluid. A large number of the affected genes are of unknown function, which means that much remains to be learned about the full influence of amniotic fluid on GBS. The majority of the observed changes in transcripts affects genes involved in basic bacterial metabolism and is connected to AF composition and nutritional requirements of the bacterium. The observation that many genes encoding adhesions are down-regulated, and genes encoding known virulence factors such as a hemolysin and a potent IL-8 proteinase are up-regulated likely have consequences for the outcome of host-pathogen interactions. Streptococcus agalactiae, serotype III strain NEM316 was grown in human amniotic fluid. Samples of bacteria were collected in mid log, late log and stationary growth phases and were used for RNA isolation for microarray analysis

Project description:Fetal wounds repair by regeneration rather than wound healing and the environment is dominated by amniotic fluid. We are looking at early transcriptional regulation of keratinocytes cultured in amniotic fluid in vitro. Keratinocytes were isolated and expanded to passage three after which they were starved in DMEM for 12h then cultured for 24h in human amniotic fluid (50%), fcs (50%) or DMEM alone for another 24h. N=2, pooled replicates per CEL-file.
