Project description:Growth and patterning of the face relies on several small buds of tissue, the facial prominences, which surround the primitive mouth. Beginning around E10 of mouse development the prominences undergo rapid growth and morphogenesis. By E11.5 the medial nasal prominences are in close apposition in the midline, as are the maxillary and medial nasal prominences on either side of the developing face. Subsequently, by E12.5 the nasal and maxillary prominences fuse to form a continuous shelf at the front of the face - the primary palate. Individual prominences are associated with specific developmental processes, and this is reflected by patterns of differential gene expression that give the prominences their unique identities. Thus, only the mandibular and maxillary prominences give rise to dentition while the frontonasal prominence has a unique role in olfaction, and the mandibular prominence in taste. We used microarrays to detail the differential gene expression program in each of the mandibular, maxillary, and frontonasal prominences during the key developmental timepoints of E10.0 through E12.5. Experiment Overall Design: Analysis of gene expression during growth and fusion of the facial prominences in the C57BL/6J mouse strain between embryonic (E) day 10.0 and 12.5. At the earliest timepoint, E10, only the mandibular prominence is a distinct entity that can be readily identified and dissected. The frontonasal prominence and the maxillary prominence are very small and not discrete from other components of the head such as the forebrain until E10.5. Analysis of these tissues at earlier timepoints would require laser capture and preamplification steps - techniques that were not used for the later timepoints. Thus samples were isolated from the mandibular prominence at E10.0 and from the mandibular, maxillary and frontonasal prominences of mouse embryos from E10.5 to E12.5, at 0.5 day intervals. In order to obtain sufficient sample for hybridization, each sample represents a pool of between 3 and 48 embryos depending on the timepoint. Specifically, the number of embryos were 40-48 for E10.0 (mandibular prominence only), 24-8 for E10.5, 8-9 for E11.0 and E11.5 and 3-4 for E12.0 and E12.5. Seven replicate samples were taken for each of the later five timepoints in each of the three prominences, with an additional seven samples for the mandibular E10.0 timepoint, for a total of 112 samples.

Project description:The face is one of the three regions most frequently affected by congenital defects in humans. In order to understand the molecular mechanisms involved it is necessary to have a more complete picture of gene expression in the embryo. Here we use microarrays to profile expression in chicken facial prominences, post neural crest migration and prior to differentiation of mesenchymal cells. Chip-wide analysis revealed that maxillary and mandibular prominences had similar expression profiles while the frontonasal mass chips were distinct. Of the 3094 genes that were differentially expressed in one or more regions of the face, a group of 56 genes was subsequently validated with quantitative PCR and a subset examined with in situ hybridization. Microarrays trends were consistent with the QPCR data for the majority of genes (81%). On the basis of QPCR and microarray data, groups of genes that characterize each of the facial prominences can be determined. We used microarrays to detail the global programme of gene expression underlying facial morphogensis Experiment Overall Design: Chicken embryos were selected at a stage after neural crest cells have ceased migration, when facial prominences have formed and prior to ctyodifferentiation of cartilage, bone, muscle. Microdissection was used to isolate facial prominences. Embryos were dissected on ice in Hanks Buffered Salt Solution and batches of 26-32 pieces were snap frozen in liquid Nitrogen. These pooled facial prominences comprised one biological replicate. A total of three biological replicates were generated for the frontonasal mass, maxillary and mandibular prominences.

Project description:This investigation provides a robust multi-dimensional compendium of gene expression data relevant to mouse facial development. It profiles the transcriptome ofectoderm and mesenchyme from the three facial prominences in a time series encompassing their growth and fusion. Analysis of the dataset identified more than 8000 differentially expressed genes comprising dramatically different ectoderm and mesenchyme programs. The mesenchyme programs included many genes identified in earlier analyses as well hundreds of genes not previously implicated in craniofacial development. The ectoderm programs included over a thousand genes that highlight epithelial structure, cell-cell interactions and signaling. The dataset includes 45 .cel files, DABG probability and RMA log2 expression values for each probeset, and statistics for 9457 probesets representing 8575 genes. 45 total samples, with 15 conditions sampling three ages (E10.5, E11.5, E12.5), three facial prominences (mandibular, maxillary and fronto-nasal) and two tissue layers (ectoderm or mesenchyme), with 3 biological replicates per condition. Differential expression was determined after median filter for variance with three-way ANOVA, Benjamini-Hochberg multiple testing correction

Project description:We present a gene expression atlas of early mouse craniofacial development. Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face We examined the facial mesenchyme and adjacent neuroepithelium at E8.5, at E9.5 we obtain cells from the facial mesenchyme, olfactory placode/epidermal ectoderm, underlying neuroepithileium, and emerging mandibular and maxillary arches. AT E10.5 we sampled the medial and lateral prominences, olfactory pit, multiple regions of the underlying neuroepithelium the mandibular and maxillary arches, and Rathke's pouch. Mouse emrbyos were harvested at developmental stage E8.5 , E9.5, and E10.5 and cells were captured from microregions responsible for the construction of the mammalian face. RNA was extracted, labelled, and quantified using the Mouse ST-l microarray.

For these 103 samples, laser capture microdissection from serial and bioreplicated E8.5, E.9.5, and E10.5 frozen sections was used to make RNA using the ZR RNA MicroPrep kit (Zymo). Nugen RiboSpia Ovation Pico WTA System V2 was used target amplification. We used starting total RNA of at least 2 ng.
