Project description:This study aims to identify the molecular basis for age-related decline in olfactory function and regeneration. To extend our characterization of olfactory stem cell regeneration during aging, we performed single-cell RNA sequencing on whole olfactory epithelium (OE) of 2-month-old and 18-month-old mice in uninjured state and at 24 hours after injury.

Transcription profiling of murine olfactory epithelium during neuronal death and replacement to study adult neurogenesis in the olfactory epithelium

Project description:Expression profiling of mRNA abundance in the adult mouse olfactory epithelium during replacement of OSNs forced by the bilateral ablation of the olfactory bulbs. The experiment was done on 6 week old male C57Bl/6 mice. Olfactory epithelium tissue samples were collected on days 1, 5, and 7 after bulbectomy. The cellular processes activated by bulbectomy include apoptosis of mature olfactory sensory neurons, infiltration of macrophages and dendritic cells, stimulation of proliferation of basal cell progenitors, and differentation of new sensory neurons.

RNA seq on olfactory epithelium cryosections

Project description:Olfactory sensory neurons (OSNs) expressing the same olfactory receptor (OR) are randomlydispersed within the same olfactory epithelial zone. To date, between 4 and 12 zones havebeen defined based on OR expression by in-situ hybridization studies. However, the totalnumber of zones, their organisation, molecular identity, and their distribution across thedorsal-ventral, anterior-posterior and lateral-medial axes are still unknown. To address thesequestions we propose to perform RNA-seq on sequential cryosections along the dorsalventraland anterior-posterior axes. This will provide a spatial dimension to the quantitativedata we already have on the number of each neuron type in the entire epithelium. We aim touse this as preliminary data for a grant application to completely resolve the 3D organisationof the olfactory epithelium at a cellular level. This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/

Mouse Olfactory Epithelium, whole olfactory mucosa, mouse

Project description:The lineage of wild-type horizontal basal cells (HBC) stem cells from the olfactory epithelium were profiled by single-cell RNA-Seq (10X v3 chemistry) to identify differences in aged versus not-aged adult stem cells mRNA expression profiles

Gene Level Expression Profiling: Activity dependent genes in the olfactory epithelium

Project description:Gene level analysis of RNA samples from mice olfactory epithelium Gene expression profiling in the olfactory epithelium was performed to obtain a better understanding of the processes mediating activity dependent gene regulation We analyzed total RNA from olfactory epithelium tissue from 3 mice at 5 days following unilateral naris occlusion (NO) using the Affymetrix Mouse Exon 1.0 ST Array, comparing unilateral and ipsilateral epithelia.

Whole-transcriptome profiling of regenerating olfactory epithelium following loss of CBX paralogs

Project description:The polycomb group protein, CBX8, is a neuron-specific component of Polycomb repressive complex 1 (PRC1) in the adult olfactory epithelium. We performed loss of function assays in an in vitro model of the regeneratng olfactory epithelium to determine the role of CBX8 in adult olfactory neurogenesis. Whole-transcriptome analysis highlighted the importance of CBX8-PRC1 in the regulation of adult neurogenesis in the olfactory epithelium.
