Project description:Cranial neural crest cells (NCC) give rise to the majority of the cartilage, bone, connective tissue, and sensory ganglia in the head, and also participate in the remodeling of the cardiac outflow tract and pharyngeal arch arteries during cardiovascular development. Our preliminary results show that targeted deletion of focal adhesion kinase (FAK) in murine NCC results in cardiovascular and craniofacial alterations, resembling human congenital heart diseases The objective of this project is to elucidate the underlying mechanisms by which FAK mediates NCC function during development. Compare gene expression in cranial neural crest cells of E11.5 wild type and FAK mutants. FAK is a tyrosine kinase that transduces integrin and growth factor signaling pathways. Abnormal growth factor signaling leads to cardiovascular malformations caused by deficient cardiac NCC function. However, a direct role for FAK in NCC morphogenesis has not been demonstrated. We will test the hypothesis that FAK is a downstream target of essential growth factor signaling in cranial neural crest cells during development. 1) Generate E11.5 mouse embryos that are either control (FAK+/flox) or NCC specific FAK knockout (Wnt1Cre;FAKflox/flox). 2) Determine genotype by PCR. 3) Dissect head and torax from the different genotypes. 4) Obtain NCC from dissected tissue by magnetic cell sorting using p75 antibody. 5) Prepare total RNA from speciments. We will pool the NCC from 3 different embryos of the same genotype, and send total RNA to TGEN for probe preparation, hybridization and array result analysis.

Project description:The overall goal of this project is to investigate the role of TGF-beta signaling in regulating the cellular metabolism of cranial neural crest (CNC) cells during palate development. Here, we conducted gene expression profiling of primary mouse embryonic palatal mesenchymal (MEPM) cells from wild type mice as well as those with a neural crest specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of cleft palate, which is among the most common congenital birth defects and observed in many syndromic conditions.

Project description:The cranial neural crest cells are pluripotent cells that provide head skeletogenic mesenchyme and are crucial for craniofacial patterning. Here, we analyzed the in vivo chromatin landscapes of mouse cranial neural crest subpopulations. Early postmigratory neural crest subpopulations contributing to distinct mouse craniofacial structures displayed similar chromatin accessibility patterns, yet differed transcriptionally. Accessible promoters and enhancers of differentially silenced genes carried H3K27me3/H3K4me2 bivalent chromatin marks embedded in large Ezh2-dependent Polycomb domains, indicating transcriptional poising. These postmigratory bivalent regions were already present in neural crest premigratory progenitors. At Polycomb domains, H3K27me3 antagonized H3K4me2 deposition, which was restricted to accessible sites. Thus, bivalent Polycomb domains provide a chromatin template for the regulation of cranial neural crest cell positional identity in vivo contributing novel insights into the epigenetic regulation of face morphogenesis.

Project description:The overall goal of this project is to investigate the role of TGF-beta signaling in tongue development in order to study the contribution of cranial neural crest (CNC) cells towards the patterning of cranial mesoderm for proper tongue formation. Here, we conducted gene expression profiling of embryonic tongue tissue from wild type mice as well as those with a neural crest specific conditional inactivation of the Tgfbr2 gene. The latter mice provide a model of microglossia, a common congenital birth defect which is frequently observed with several syndromic conditions.

The latter mice provide a model of microglossia, a common congenital birth defect which is frequently observed with several syndromic conditions. To investigate the mechanism of microglossia resulting from dysfunctional TGF-Beta signaling during muscle development, we analyzed neural crest specific conditional inactivation of Tgfbr2 in mice (Tgfbr2fl/fl;Wnt1-Cre). We performed microarray analyses of tongue tissue of Tgfbr2fl/fl;Wnt1-Cre mutant mice and Tgfbr2fl/fl control mice at embryonic day E14.5 (n=3 per genotype) to examine the genes regulated by Tgf-beta during tongue muscle development.
