Expression Profiling of the Developing Mouse Lung

ABSTRACT: Mammalian lung development is a complex morphogenetic process, which initiates near mid-gestation and continues through early postnatal life. The lung arises as two lateral buds that emerge from the ventral foregut endoderm at ~ 9 days after fertilization (in mouse) and undergo numerous rounds of dichotomous branching to form the bronchial tree. This stage of development is referred to as the pseudoglandular phase, histologically characterized by loose mesenchyme surrounding undifferentiated epithelial tubes. We have undertaken a comprehensive gene expression profiling of the entire process of murine lung development using oligonucleotide-based microarrays. Our data reveals the expression pattern of ~ 11,000 genes throughout the morphologic stages of lung development. Examination of the data confirms previously known patterns of expression for extracellular matrix genes and provides new information regarding relationships in temporal expression among groups of these genes. Large-scale cluster analysis reveals associations in the expression profile of specific genes with defined developmental processes. Keywords: time course

Transcription profiling of mouse lung from E18, P1, P4, P7, P10, P14, P21, and adult) or pooled (E12, E14, E16) - developmental series

Experiment Overall Design: RNA was isolated from individual (E18, P1, P4, P7, P10, P14, P21, and adult) or pooled (E12, E14, E16) whole lungs using a modified guanidinium:phenol extraction method.Ten micrograms of total RNA was used to generate target cRNA for hybridization to Affymetrix Mu11K chipset subA and subB oligonucleotide microarrays. A single chip set was used for each time-point. Before target generation, individual RNA samples were pooled so that each target was derived from a minimum of three individual lungs.

Characterization of the mid-foregut transcriptome identifies genes regulated during lung bud induction.

Project description:To identify genes expressed during initiation of lung organogenesis, we generated transcriptional profiles of the prospective lung region of the mouse foregut (mid-foregut) microdissected from embryos at three developmental stages between embryonic day 8.5 (E8.5) and E9.5. This period spans from lung specification of foregut cells to the emergence of the primary lung buds. We identified a number of known and novel genes that are temporally regulated as the lung bud forms. Genes that regulate transcription, including DNA binding factors, co-factors, and chromatin remodeling genes, are the main functional groups that change during lung bud formation. Members of key developmental transcription and growth factor families, not previously described to participate in lung organogenesis, are expressed in the mid-foregut during lung bud induction. These studies also show early expression in the mid-foregut of genes that participate in later stages of lung development. This characterization of the mid-foregut transcriptome provides new insights into molecular events leading to lung organogenesis. Three samples (developmental stages), three biological replicates (5-10 pooled mid-foreguts)

Genome wide gene expression during lung development in three inbred mouse strains

Project description:To better understand the temporal dynamics of gene expression during normal murine lung development we characterized global gene expression at 26 time points in three common inbred strains of mice (A/J, C57BL/6J, and C3H/HeJ). The data set provides a unique resource for identifying patterns of gene expression changes during normal lung development and for investigating the developmental origins of respiratory disease. The transcriptional profiles generated for lung development in three inbred strains of the laboratory mouse revealed concordance with pre-natal stages of lung development defined by anatomy and morphology. The genomic data support the view that the postnatal alveolar development is composed of 4 distinct molecular stages. The data revealed strain specific differences in the expression of genes related to respiratory cell differentiation, pulmonary innervation, metabolic pathway interactions, and immune system function. Mouse lungs or whole embryos (e09.5 only) were surgically dissected at 26 time points across all six canonical stages of lung development (embryonic-EMB, pseudoglandular-PSG, canalicular-CAN, saccular-SAC, alveolar-ALV, homeostatic-HOM) to identify transcriptional profiles associated with 9 molecular divisions of lung development (embryonic-EMB, pseudoglandular-PSG, canalicular-CAN, saccular-SAC, alveolar1-ALV1, alveolar2-ALV2, alveolar3-ALV3, alveolar4-ALV4, homeostatic-HOM). Lung tissue from three or four embryos collected at e11.5 or e12.5, respectively, was pooled for each sample to obtain sufficient RNA for array analysis. Tissue from at least three animals was collected for each time point (biological replicates). Only male mice were used in the study.

Transcriptomic profiling of human alveolar organoids(hALOs)

Project description:We performed global transcriptomic profiling of hALOs at early (P4), middle (P13) and late (P20) passages and found that the transcripts of the hALOs were similar to that of primary lung progenitor organoids.hALOs highly expressed genes associated with lung development/lung progenitor, AT2 specification and AT1 specification.We found that our hALOs were more similar to pseudoglandular-staged lung.The gene sets associated with alveolar maturation, such as surfactant homeostasis or response to oxygen levels, were upregulated in P20. Besides, genes involved in endoderm development or respiratory tube development were downregulated

Sex-Specific Differences in MicroRNA Expression during Human Fetal Lung Development

Project description:Our study demonstrates differential expression of numerous autosomal miRNAs between the male and female developing human lung. Additionally, the expression of some miRNAs are modified by age across the pseudoglandular stage in a sex-specific way. Some of these differences in miRNA expression may impact susceptibility to pulmonary disease later in life. Our results suggest that sex-specific miRNA expression during human lung development may be a potential mechanism to explain sex-specific differences in lung development and may impact subsequent disease susceptibility

miRNA gene expression in the pseudoglandular phase

Project description:MicroRNA expression levels were assessed during the pseudoglandular phase of normal fetal lung development at the critical time, when the the conducting airways are formed. Precise miRNA regulation is important for proper pulmonary organogenesis, supporting the delicate balance between expansion of progenitor cells and their terminal differentiation. Microarray analyses could indicate the potential involvement of miRNAs important for human pulmonary hypoplasia. Two replicates of pooled RNA from two 9 week old fetal lung samples

Expression data from Ezh2 epithelial knock-out mouse lungs at E14.5

Project description:Ezh2 epigenetically suppresses developmentally-regulated genes. Ezh2 is highly expressed during development, including in the lung. We knocked out Ezh2 in the developing lung epithelium using a Shh-cre driver which is active in foregut endoderm prior to lung morphogenesis. Many developmentally regulated genes became derepressed in the mutant lungs, leading to defects in lung development. Microarray analysis of genes upregulated in Ezh2 epithelial knock-out mouse lungs compared to Shh-cre controls.

Project description:Human fetal lung tip cells were purifed from developing human lungs at pseudoglandular and canalicular stages and in vitro cultured; pseudoglandular organoids and LinPOS organoids, respectively. Alveolar organoids were differentiated from LinPOS organoids in the alveolar differentiation condition. Differential NKX2.1 binding patterns in each organoid were profiled by targeted DamID-seq.
