Expression data of E13.5 mouse Blood Brain Barrier and lung endothelial cells

ABSTRACT: Following the identification of a critical time window of Blood Brain Barrier formation in the mouse embryo, we aimed to identify genes important for barriergenesis. To this end, we isolated cortical and lung E13.5 endothelial cells and compared expression between the two populations. The working hypothesis was that endothelial cells which are actively building a barrier would have a uniqe pattern of gene expression that would be detectable in comparison to a non-barrier endothelial population that is also active in vasculogenesis. E13.5 Tie2-GFP embryos were micro-dissected for cortex and lungs. Cortex tissue was carefully cleared of the meninges and choroid plexus. FACS purification of GFP positive cells and GeneChip analysis was applied . All material from a single litter (10-13 embryos) was pooled and considered as a biological replicate. n=4 litters.

Gene expression profiles of E15.5 endothelial cells (GUDMAP Series_id: 38)

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing kidney. The central thesis is straightforward. The combination of fluorescent activated cell sorting (FACS) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing kidney. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene in FACS isolated components of the developing kidney. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. Tie2-GFP transgenic mice were utilized to isolate the endothelial cell population from E15.5 embryonic kidneys. The endothelial cells were isolated from embryos using trypsin treatment and FACS. The RNA was isolated from purified endothelial cells and the gene expression profiles were determined by microarrays.

Expression data from E13.5 Fetal Liver LSK Hes1-GFP positive and E13.5 Fetal Liver LSK Hes1-GFP negative

Project description:Notch signaling defines a conserved, fundamental pathway, responsible for determination in metazoan development and is widely recognized as an essential component of lineage specific differentiation and stem cell self-renewal in many tissues including the hematopoietic system. Until recently, the majority of studies in the hematopoietic system focused on Notch signaling in lymphocyte differentiation and knowledge of individual Notch receptor roles in early hematopoiesis has been limited due to a paucity of genetic tools available To fate-map Notch receptor expression and pathway activity in the hematopoietic system we used tamoxifen-inducible CreER knock-in mice for individual Notch receptors in combination to a novel Notch reporter strain (Hes1GFP) and a conditional gain of function allele of Notch2 receptor (Rosa-lsl-ICN2). E13.5 Foetal Liver lineage negative, cKit+, Sca1+ cells were sorted from Hes-GFP mice for RNA extraction and hybridization on Affymetrix microarrays

Gene-expression changes in neurons active during contextual fear conditioning compared to controls left in the homecage

Project description:This experiment uses a transgenic mouse that allows for activity-induced expression of an HA-tagged ribosome in an inducible and cre-dependent manner. This allowed us to assess long-lasting gene-expression changes in neurons active during contextual fear conditioning. Previous studies have used similar systems to look a transient changes in gene expression in these neurons, but we developed a system to look at long lasting changes. The workflow includes tissue dissection of the prefrontal cortex, tissue homogenization followed by an immunoprecipitation of the tagged ribosomes using antibodies against HA. RNA bound to the ribosomes is then purified, a cDNA library is prepared and RNAseq was performed. The experimental group was fear conditioned and the control group was left in their homecage for induction of HA- expression in active neurons.

Expression data of the endothelial-to-hematopoietic transition in E8.5 concepti

Project description:During development a specialised subset of endothelial cells, the haemogenic endothelium, undergo an endothelial-to-haematopoietic transition. This process critically involves the transcription factor Runx1. Here we have isolated a specific subpopulation of endothelial cells using a Runx1 enhancer-reporter transgenic mouse line (23GFP). We have compared the gene expression profile of this population to non-23GFP expressing endothelial cells and CD41 expressing haematopoietic progenitor cells to assess whether 23GFP expression marks a biologically distinct subset of endothelium. We used affymetrix microarrays to detail the global programme of gene expression underlying the different populations and identified a distinct expression profile of the 23GFP expressing endothelium. 23GFP transgenic mouse embryos were dissected free of the ectoplacental cone at embryonic day E8.5, pooled, and sorted into 23GFP- and 23GFP+ endothelial (VE-Cad+ Ter119- CD45- CD41-) and CD41+ haematopoietic cells (VE-Cad+ Ter119-CD45-CD41+23GFP+) cells by FACS. Triplicate samples for each cell population were analysed. cDNA synthesis, fragmentation, and hybridisation were performed by the Stanford Protein and Nucleic Acid Facility.

Culture induced changes in Blood-Brain Barrier transcriptome: implications for amino acid transporters in vivo

Project description:Tight homeostatic control of brain amino acids (AA) depends on transport via solute family carrier proteins expressed by the Blood-Brain Barrier (BBB) microvascular endothelial cells (BMEC). To characterize the mouse BMEC transcriptome and probe culture-induced changes microarray analyses of PECAM-1+ endothelial cells (ppMBMECs) were compared with primary MBMECs (pMBMEC) cultured in the presence or absence of glial cells, and with b.End5 endothelioma cell-line. Selected cell marker and AA transporter mRNA levels were further verified by real-time RT PCR. Regardless of glial co-culture expression of a large subset of genes was strongly altered by a brief culture step. This is consistent with the known dependence of BMECs on in vivo interactions to maintain physiological functions, e.g. tight barrier formation, and their consequent de-differentiation in culture. Seven (4F2hc, Lat1, Taut, Snat3, Snat5, Xpct, Cat1) of nine highly in vivo expressed AA transporter mRNAs were strongly down-regulated for all cultures and two (Snat2, Eaat3) were variably regulated. In contrast, five AA transporter mRNAs with low in vivo expression, including y+Lat2, xCT, and Snat1, were strongly up-regulated by culture. We hypothesized that the AA transporters highly expressed in ppMBMECs and strongly down-regulated in culture play a major in vivo role for BBB transendothelial transport. Keywords: culture vs non-cultured RNA was prepared from 4 sources of endothelial cells: 1) isolated mouse brain microvascular endothelial cells that were cultured in transwells with and 2) without non-contact co-culture with glial cultures or 3) further purified using anti-PECAM1 magnetic bead sorting and 4) the endothelioma b.End5 cell-line.
