Project description:Brain of the foxf2 mutant mouse embryo shows microvascular aneurysm, underdeveloped blood brain barrier and also significant defects in the tissue integrity. Foxf2 expresses in the pericytes of the brain and seem to play an important role in proper development of the BBB. Brains of E18.5 wt and foxf2 mutant mouse embryos dissected and RNA extracted from the brains using Sigma mammalian total RNA extraction kit. The RNA then been sent to th core facility for hybridization.

Project description:The blood-brain barrier (BBB) consists of specific physical barriers, enzymes and transporters, which together maintain the necessary extracellular environment of the central nervous system (CNS). The main physical barrier is found in the CNS endothelial cell, and depends on continuous complexes of tight junctions combined with reduced vesicular transport. Other possible constituents of the BBB include extracellular matrix, astrocytes and pericytes, but the relative contribution of these different components to the BBB remains largely unknown. Here we demonstrate a direct role of pericytes at the BBB in vivo. Using a set of adult viable pericyte-deficient mouse mutants we show that pericyte deficiency increases the permeability of the BBB to water and a range of low-molecular-mass and high-molecular-mass tracers. The increased permeability occurs by endothelial transcytosis, a process that is rapidly arrested by the drug imatinib. Furthermore, we show that pericytes function at the BBB in at least two ways: by regulating BBB-specific gene expression patterns in endothelial cells, and by inducing polarization of astrocyte end-feet surrounding CNS blood vessels. Our results indicate a novel and critical role for pericytes in the integration of endothelial and astrocyte functions at the neurovascular unit, and in the regulation of the BBB. The brain microvascular fragments were isolated from mice with different genotypes, each represented by 3-4 biological replicates. Genotypes 1-2: Platelet derived growth factor-B (PDGF-B) retention-motif knockout (pdgfbret/ret) represent the pericyte-deficient situation, and the heterozygous mice (pdgfbret/+) are used as controls. Genotypes 3-4: Hypomorphic PDGF-B mutants that rescue pdgfb-/- null mice, in which a one copy of a conditionally silent human PDGF-B transgene targeted to the Rosa 26 locus (R26P) is turned on by endothelial-specific expression of Cre recombinase. In this data set these mice are named as Tie2Cre, R26P+/0, pdgfb-/- (representing the pericyte-deficient situation). Mice wt for pdgfb (pdgfb+/+) and carrying one silent copy of R26P (R26P+/0), are used as controls. Genotype 5: Adult Notch3+/+ wildtype (WT).

Project description:To identify the genes and pathways regulated by FOXF2, we investigated potential FOXF2 gene targets by microarray analyses of primary prostate stromal cells (PrSC) in which FOXF2 was knocked down by siRNA. 190 differentially expressed genes were selected, of which 104 genes were more highly expressed in PrSC cells treated with FOXF2 siRNA and 86 were more highly expressed in PRSC cells treated with negative control siRNA. Experiment Overall Design: In each experiment, we compared gene expression of PrSC cells treated with FOXF2 siRNA versus PrSC cells treated with negative control siRNA, in a total of 6 affymetrix arrays. 190 differentially expressed genes were selected (ratio negative control siRNA/siRNA ⥠2log |0.8| as average in all arrays).

Project description:Reconstitution of a neurovascular unit model with blood-brain barrier (BBB) function is of great importance for drug development targeting cerebral diseases and study of brain disease mechanisms. In this study, we describe a human neurovascular unit chip designed by reconstituting necessary cellular and extracellular components in microfluidic devices. Dynamic three-dimensional co-culture of human cells (neural stem cells, brain microvascular endothelial cells, and brain vascular pericytes) in microfluidics with a stepwise unidirectional flow successfully established the chip with BBB-mimetic structural and functional features to be an effective barrier for drugs and cytokines. Furthermore, we showed the utility of the chip by modeling the neurotropic behaviors and BBB penetration process of a global fungal meningitis pathogen, Cryptococcus neoformans. This chip is the first in vitro experimental model for monitoring neurotropism of C. neoformans and would contribute to the investigation of various cerebral disorders, including microbial infectious diseases and their corresponding drug development.

Project description:Cleft palate is among the most common structural birth defects in humans. Previous studies have shown that mutations in FOXF2 are associated with cleft palate in humans and mice and that Foxf2 acts in a Shh-Foxf-Fgf18-Shh molecular network controlling palatal shelf growth. In this study, we generated mice carrying 3xFLAG epitope-tagged endogenous Foxf2 protein using the CRISPR/Cas9-mediated genome editing technology and characterized genome-wide Foxf2 binding sites in the developing palatal shelves using chromatin immunoprecipitation and genome sequencing (ChIP-seq). By combined analysis of ChIP-seq and RNA-seq datasets we identified a large list of Foxf2 target genes. Further analyses demonstrate that Foxf2 directly regulate expression of several genes encoding ECM or ECM modifiers during palate development. Moreover, our ChIP-seq and RNA-seq datasets provide an excellent resource for comprehensive understanding of the molecular network controlling palate development.

Project description:The blood-brain barrier (BBB) is a multicellular neurovascular unit (NVU) that allows the selective passage of necessary molecules into the central nervous system (CNS), while limiting the entry of neurotoxins and most drugs. A crosstalk with pericytes and neural cells mediates the acquisition of specialized properties, such as the formation of tight junctions (TJs), in brain microvascular endothelial cells (BMECs). TJs limit the paracellular passage of solutes, thereby regulating CNS homeostasis. However, the mechanisms by which NVU cells communicate to mediate TJ formation remains a mystery. Retinoic acid (RA), a key signaling molecule during vertebrate embryonic development, is commonly used to enhance functional barrier properties in in vitro BBB models. However, its physiological relevance and affected pathways are not fully understood.

Project description:We performed single cell RNA-Seq of FACS-isolated CD45+ leukocytes and Lin-CD24- prostate stromal cells from Col1a2-TRAMP(Control) group and Col1a2-Foxf2-TRAMP group. Unsupervised clustering analysis on integrated single-cell datasets revealed an increased CD8+ T cell frequency and activity and a decreased Macrophage and MDSC activity in the Col1a2-Foxf2-TRAMP mice. The analysis in TRAMP mice revealed two major subpopulations that represented the myofibroblastic CAF (myCAF) and inflammatory CAF (iCAF). The percentage of myCAF increased by 15% in the Col1a2-Foxf2-TRAMP mice, suggesting that Foxf2 induced a shift toward the myCAF phenotype. On the other hand, the overall CAF gene signature score defined by the average expression of 30 CAF-associated genes on a single cell level was slightly but significantly reduced in the Col1a2-Foxf2-TRAMP mice.

Project description:Purpose: The purpose of this study is to compare the transcriptome expression profiles of E13.5 Foxf2-/-;Osr2RFP/+ and control palatal mesenchyme by using RNA-seq analysis. Methods: Foxf2+/- female mice were crossed with Foxf2+/-;Osr2RFP/+ male mice.The embryos were harvested at E13.5. The pair of palatal shelves were dissected from each Osr2-RFP+ embryo. The RFP+ palatal mesenchyme cells were isolated by using fluorescence-activated cell sorting (FACS). RNA-seq analysis was carried out using the FACS-isolated palatal mesenchyme from Foxf2-/-;Osr2RFP/+, Foxf2+/-;Osr2RFP/+ and Osr2RFP/+embryos, respectively.
