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: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: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.

Project description:The overall goal of this project is to investigate the role of TGF-beta signaling in tissue-tissue interactions between myogenic precursors of craniofacial muscles and cranial neural crest cells (CNCCs). Here, we conducted gene expression profiling of the mandibular arch from mice at embryonic day E11.5 with a CNCC-specific conditional inactivation of the TGF-beta receptor type 1 gene Alk5. These mice provide a model of microglossia as well as disrupted extraocular and masticatory muscle development, which are congenital birth defects commonly observed in several syndromic conditions. To investigate the adverse effects of dysfunctional TGF-beta signaling on tissue-tissue interactions between CNCCs and myogenic precursors of craniofacial muscles, we analyzed mandibular arch tissue of mice with a CNCC-specific conditional inactivation of Alk5 (Wnt1-Cre; Alk5 fl/fl). We performed microarray analyses of the mandibular arch of Alk5 fl/fl control mice and Wnt1-Cre; Alk5 fl/fl mutant mice, collected at embryonic day E11.5 (n=4 per group).

Project description:The Hox genes play a key role in specifying the axial identity of neural crest cells (NCCs) migrating into the pharyngeal arches of the developing mouse embryo. In the absence of Hoxa2, NCC derivatives of the second pharyngeal arch (PA2) duplicate those formed by NCCs of the first arch (PA1). In this study, we use bulk and single-cell RNAseq to establish the molecular mechanisms driving this phenotypic reversion to a ground state. Comparing the transcriptomes of PA1 and PA2 in wildtype and Hoxa2-/- embryos during NCC migration and differentiation, we find that Hoxa2-/- PA2 does not revert to a molecular ‘ground state’ corresponding to the NCC derivatives. This separation of phenotypic and molecular states has significant implications for our understanding of NCC biology. We also identify putative targets through which HOXA2 likely acts to impart PA2 identity. The heterogenous expression of these targets within the PAs and their responses to the absence of HOXA2 suggest that subsets of NCCs may respond to HOXA2 activity in distinct manners related to their ultimate fate. To understand the heterogeneity of neural crest cells (NCCs) and other tissues of pharyngeal arches (PAs) 1 and 2 in the mouse embryo at E10.5, during NCC differentiation, we collected PA1 and PA2 from wildtype embryos and Hoxa2-/- embryos. We used the 10x Chromium single-cell sequencing system to compare the transcriptional profiles between PA1 and PA2 as well as wildtype and Hoxa2-/- PAs.

To understand the specification of axial identity in neural crest cells (NCCs), we collected pharyngeal arches (PAs) 1 and 2 from mouse embryos at four time points during NCC migration and the beginning of differentiation (E9.0, E9.5, E10.0, and E10.5). We collected these tissues from both wildtype embryos and embryos homozygous for a mutation abrogating Hoxa2 expression. By performing comparative analysis of these tissues, we set out to understand the molecular underpinnings of NCC axial identity, as well as the mechanistic role of Hoxa2 in establishing PA2 identity.
