Project description:Laser capture microdissection coupled with microarray genes expression analysis were utilized in order to elucidate the regulatory networks active in epithelial cells of the neonatal and adult mouse uterus. Genes predominantly expressed in the glandular epithelium (GE) in the neonatal or adult uterus were determined by comparing transcripts in the isolated samples of luminal epithelium (LE) and GE from postnatal day (PD) 10, day of psudopregnancy (DOPP) 2.5 or DOPP 3.5 uteri (n=2/cell type/day).

Project description:The uterus is an essential organ for reproduction in mammals, however the cellular and molecular mechanisms that direct its development remain insufficiently understood. To fill this knowledge gap, the epithelium of the neonatal mouse uterus was isolated and subjected to single cell transcriptome (scRNA-seq) analysis. Substantial differences in transcriptional profiles and cell types were evident as the epithelium developed from postnatal days 1 to 15. Both the undifferentiated epithelium and determined luminal epithelium were heterogeneous and contained several different cell clusters. Novel glandular epithelial-specific genes (Gas6 and Cited4) were validated by in situ hybridization during uterine development. Trajectory analyses provided a framework for understanding epithelium maturation and differentiation of the glandular epithelium. A candidate set of transcription factors and gene regulatory networks were identified that regulate epithelium lineage specification and morphogenesis. This atlas provides foundational insights important for future mechanistic studies focused on uterine epithelium morphogenesis during the critical window of postnatal development.

Project description:Fetal and neonatal beta cells have poor glucose-induced insulin secretion and only gain robust glucose responsiveness several weeks after birth. This unresponsiveness may be due to a generalized immaturity of the metabolic pathways normally found in beta cells. Gene expression profile of neonatal (1 day old) and young adult (6 weeks old) Sprague-Dawley rat islets were evaluated and compared. Frozen sections were obtained from pancreases of neonatal (1 day old) and young adult (6 weeks old) Sprague-Dawley rats. The beta cell enriched cores of the islets were excised using laser capture microdissection. RNA was extracted, amplified and subjected to microarray analysis.

Project description:The upper Müllerian duct (MD) is patterned and specified into two morphologically and functionally distinct organs, the oviduct and uterus. It is known that this regionalization process is instructed by inductive signals from the adjacent mesenchyme. However, the interaction landscape between epithelium and mesenchyme during upper MD development remains largely unknown. Here, we performed single-cell transcriptomic profiling of mouse neonatal oviducts and uteri at the initiation of MD epithelial differentiation (postnatal day 3). We identified major cell types including epithelium, mesenchyme, pericytes, mesothelium, endothelium, and immune cells in both organs with established markers. Moreover, we uncovered region-specific epithelial and mesenchymal subpopulations and then deduced region-specific ligand-receptor pairs mediating mesenchymal-epithelial interactions along the craniocaudal axis. Unexpectedly, we discovered a mesenchymal subpopulation marked by neurofilaments with specific localizations at the mesometrial pole of both the neonatal oviduct and uterus. Lastly, we analyzed and revealed organ-specific signature genes of pericytes and mesothelial cells. Taken together, our study enriches our knowledge of upper Müllerian duct development, and provides a manageable list of potential genes, pathways, and region-specific cell subtypes for future functional studies.

Project description:Here we compare the gene expression profiles of two distict, fluorescently identified neuronal populations, the motor neruons (MN) and the decending commissural interneurons (dCIN) of the neonatal rat spinal cord isolated with laser microdissection. These two populations participate in the neuronal networks in the spinal cord where they have destinct functions in shaping (dCINs) and transferring the output to the muscles (MNs) during locomotion. We wished to determine how the functinal differences in these nerurons are manifested at the gene expression level. Keywords: Cell type comparison.

Project description:Abstract. Very little is known regarding how hormonal exposures impact the epigenetic landscape of developing tissues in the context of a whole organism, in contrast to the impact on cultured cells. Here we took a global approach to understanding how neonatal exposure to the xenoestrogen, diethylstilbestrol (DES), alters the uterine epigenome. RNA-seq and ChIP-seq (H3K4me3, H3K27me3, H3K27ac and H3K4me1) were performed on DES-treated and control uteri. The most striking finding was differential association of H3K27ac and H3K4me1 at typical and super-enhancer regions of 79% of altered genes. These peaks overlapped with previously reported estrogen receptor a (ERα) ChIP-seq peaks. Conditional uterine deletion of ERα (Esr1cKO) conferred protection of 88% of altered genes. H3K27ac ChIP-seq on Esr1cKO samples showed that 72% of protected genes had a differential H3K27ac enhancer. These data suggest that DES regulates gene expression in the neonatal mouse uterus by H3K27ac association at ERα binding sites near estrogen-regulated genes.

Project description:Forkhead box A2 (FOXA2) is a critical regulator of endometrial gland development in mice. In the adult mouse uterus, FOXA2 is expressed solely in the GE cells of the endometrium. Conditional deletion of Foxa2 after birth in the uterus, using the progesterone receptor Cre mouse (PgrCre), impeded gland development, thereby rendering the adult mouse infertile due to defects in blastocyst implantation stemming from a lack of endometrial glands and their secretions. As a first step to begin understanding the FOXA2 function in the endometrial glands of the uterus, genome-wide investigation of in vivo FOXA2 and RNA polymerase II (POL2) binding target regions in the neonatal and adult uterus was determined by chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq). In order to determine the transcriptional regulatory networks mediating FOXA2 regulation of endometrial gland development and function, chromatin immunoprecipitation and massively parallel sequencing (ChIP-Seq) was used to create a genome-wide profile of in vivo FOXA2-binding sites in the developing (PD 12) and adult (DOPP 2.5 and 3.5) mouse uterus.

Spinal cord were then snap frozen, cryosectioned and fluorescent single cells were laser dissected into a collector tube to a total of ca. 50-200 cells pr sample. RNA was then extracted, two round amplified and hybridized to Affymatrix RNU-34 chips. 22 samples were hybridized onto chips, 7 MNs, 7 CINS and 8 MIX.
