Project description:Transcriptional profiling of mouse 4-8 somite microdissected otic placodes from Fgf3/Fgf10 double heterozygotes (controls) compared to Fgf3/Fgf10 double null mutants. The purpose was to determine the effectors that are induced (or repressed) by Fgf3 and Fgf10 in the course of otic placode induction. Two condition experiment, double heterozygote vs. double null placodes. Biological replicas: 3 Fgf3+/-;Fgf10+/- and 3 Fgf3-/-;Fgf10-/- pools of ten placodes each.

Project description:The inner ear develops from a patch of thickened cranial ectoderm adjacent to the hindbrain called the otic placode. Studies in a number of vertebrate species suggest that the initial steps in induction of the otic placode are regulated by members of the Fibroblast Growth Factor (FGF) family, and that inhibition of FGF signaling can prevent otic placode formation. To better understand the genetic pathways activated by FGF signaling during otic placode induction, we performed microarray experiments to estimate the proportion of chicken otic placode genes that can be up-regulated by the FGF pathway in a simple culture model of otic placode induction. Surprisingly, we find that FGF is only sufficient to induce about 15% of chick otic placode-specific genes in our experimental system. However, pharmacological blockade of the FGF pathway in cultured chick embryos showed that although FGF signaling was not sufficient to induce the majority of otic placode-specific genes, it was still necessary for their expression in vivo. These inhibitor experiments further suggest that the early steps in otic placode induction regulated by FGF signaling occur through the MAP kinase pathway. Although our work suggests that FGF signaling is necessary for otic placode induction, it demonstrates that other unidentified signaling pathways are required to co-operate with FGF signaling to induce the full otic placode program. 8 samples were analyzed. These contain two replicates of each of the following four catergories: Otic ectoderm, Non-Otic (lateral) ectoderm, Trigeminal Ectoderm cultured - FGF, Trigeminal Ectoderm cultured + FGF

Project description:The first morphological evidence of the developing ear is a thickened disk of ectoderm known as the otic placode. However, signals for otogenesis are present even before the otic placode is physically apparent. Several inductive signals have been identified through candidate gene approaches, but there are still many gaps in the signaling cascade of otogenesis. Presently the candidate gene approach has largely exhausted known candidates. This project compares the pre-otic domain with a control region that is competent, but not specified to form otic placode. The purpose of this work is to identify genes that are differentially expressed in the pre-otic domain in order to generate a list of novel candidate genes for otic placode induction.

Project description:Wild-type and mouse mutants for FGF3, FGF10 and FGF3/FGF10 double mutants at embryonic day E10 were analysed by microarrays for downregulated genes. A tissue sample corresponding to an area containing the otic vesicle and surrounding mesenchyme and neighboring hindbrain were isolated from E10 embryos (See Figure 3A of manuscript). Five samples were pooled for RNA preparation. Samples were isolated from wild-type, FGF3, FGF10 and FGF3/FGF10 double mutants. Two RNA samples for each genotype were generated (corresponding to 8 tissue samples). RNA was labeled and hybridized with Affymetrix U74A V2 arrays.
