Project description:We report the application of single cell RNA sequencing for determining cell type and quantity in developing inner ear organoids derived from human pluripotent stem cells. By obtaining samples from multiple time points throughout differentiation, we developed a roadmap at single cell resolution of the multiple cell lineages which give rise to in vitro inner ear tissue as well as 'off-target' tissue types. We find that the cells in the day 0 sample contained primarily a homogenous population of pluripotent stem cells. On day 3, after treatment with BMP4, we find that the cells have differentiated into a split between surface ectoderm, the progenitor of the inner ear tissue, and neuroectoderm. On day 6 and 8, we observed the emergence of cranial placode tissue, both anterior and posterior. Then, after treatment starting on day 8 with a WNT agonist, CHIR, we observed the maturation of inner ear tissue into hair cells and neurons, starting on day 18 and increasing through the last time point collected, day 36. This study provides an atlas of inner ear organoid differentiation from human pluripotent stem cells.

Project description:The inner ear continues to grow and develop until the auditory and vestibular systems reach full maturity and all of the genes involved in this process have yet to be identified. Previous gene based analysis have primarily focused on the early developmental stages following induction and initial formation of the inner ear. The aim of this study is to identify new candidate genes for inner ear development. Microarrays were used to produce expression profiles from larval stages 56,57,58 of the Xenopus laevis inner ear. The data produced from this work represent an annotated resource that can be utilized by the Xenopus community to provide candidates for further functional analysis. Xenopus inner ears were isolated from larval animals for RNA extraction and hybridization to Affymetrix GeneChip microarrays.

Project description:We implemented a functional genomics approach as a means to undertake a large-scale analysis of the Xenopus laevis inner ear transcriptome through microarray analysis. Microarray analysis uncovered genes within the X. laevis inner ear transcriptome associated with inner ear function and impairment in other organisms, thereby supporting the inclusion of Xenopus in cross-species genetic studies of the inner ear. Gene expression analysis of Xenopus laevis juvenile inner ear tissue. Inner ear RNA isolated from three groups of 5-10 juvenile X. laevis. Each biological replicate represents pooled inner ear RNA from 10-19 inner ears.

Project description:Objective: Otitis media is known to alter expression of cytokine and other genes in the mouse middle ear and inner ear. However, whole mouse genome studies of gene expression in otitis media have not previously been undertaken. Ninety-nine percent of mouse genes are shared in the human, so these studies are relevant to the human condition. Methods: To assess inflammation-driven processes in the mouse ear, gene chip analyses were conducted on mice treated with trans-tympanic heat-killed Hemophilus influenza using untreated mice as controls. Middle and inner ear tissues were separately harvested at 6 hours, RNA extracted, and samples for each treatment processed on the Affymetrix 430 2.0 Gene Chip for expression of its 34,000 genes. Results: Statistical analysis of gene expression compared to control mice showed significant alteration of gene expression in 2,355 genes, 11% of the genes tested and 8% of the mouse genome. Significant middle and inner ear upregulation (fold change >1.5, p<0.05) was seen in 1,081 and 599 genes respectively. Significant middle and inner ear downregulation (fold change <0.67, p<0.05) was seen in 978 and 287 genes respectively. While otitis media is widely believed to be an exclusively middle ear process with little impact on the inner ear, the inner ear changes noted in this study were numerous and discrete from the middle ear responses. This suggests that the inner ear does indeed respond to otitis media and that its response is a distinctive process. Numerous new genes, previously not studied, are found to be affected by inflammation in the ear. Conclusion: Whole genome analysis via gene chip allows simultaneous examination of expression of hundreds of gene families influenced by inflammation in the middle ear. Discovery of new gene families affected by inflammation may lead to new approaches to the study and treatment of otitis media. There are 6 control samples and 8 samples trans-tympanically injected with H flu 10e9 for 6 hours. Each sample is a pool of 4 animals
