Project description:This study was conducted to examine normal gene expression in the pharyngeal arch during mouse embryonic development Wild type embryonic tissue containing the pharyngeal arches was collected from five independent samples (n=5) at stage E10.5 by dissection. Total RNA was isolated for analysis by Affymetrix mouse genome 430A GeneChip.
Project description:modENCODE_submission_2548 This submission comes from a modENCODE project of Robert Waterston. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: Our experiments are designed to detect all C. elegans transcripts by hybridizing RNA to commerically available genome tiling arrays. To maximize the chances of detecting rare transcripts with limited expression in specific cells, we are extracting RNA from selected embryonic cells isolated by FACS and from postembryonic cells by use of the mRNA tagging method. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf Keywords: Transcript tiling array analysis EXPERIMENT TYPE: Transcript tiling array analysis. BIOLOGICAL SOURCE: Strain: NC1293 (engineered, target gene myo-2 tagged by GFP); Tissue: pharyngeal muscle; Developmental Stage: Mixed stage of embryos 20dC; Genotype: ccIs9753[myo-2::GFP]; Sex: Hermaphrodite; NUMBER OF REPLICATES: 3; EXPERIMENTAL FACTORS: Strain NC1293 (engineered, target gene myo-2 tagged by GFP); temperature 25; Developmental Stage Mixed stage of embryos 20dC; Tissue pharyngeal muscle
Project description:The aim of this study was to identify differentially expressed genes within the pharyngeal arches of Pax9-null embryos at E9.5. Mice null for Pax9 die in the neonatal period with complex cardiovascular defects, caused by abnormal morphogenesis of the pharyngeal arch arteries.
Project description:We have developed a novel in vitro protocol for the derivation of bona fide Pharyngeal Endoderm (PE) cells from hESCs. We demonstrated that our PE cells robustly express Pharyngeal Endoderm markers, they are transcriptionally similar to PE cells isolated from in vivo mouse development and represent a transcriptionally homogeneous population. Importantly, we elucidated the contribution of Retinoic Acid in promoting a transcriptional and epigenetic rewiring of PE cells. In addition, we defined the epigenetic landscape of PE cells by combining ATAC-Seq and ChIP-Seq of histone marks. This SuperSeries is composed of the SubSeries listed below.
