Project description:We report bulk RNAseq of in vitro cultured horizontal basal cells, and in vivo isoalted respiratory basal cells of the murine olfactory epithelium, and compared their profiles with pre-existing bulk RNAseq of in vivo isolated HBCs and single cell RNAseq of in vivo HBCs.
Project description:We used trasncriptional profiling of fluorescent activated cell sorting (FACS) purified ICAM1-positive and negative cells from the olfactory epithelium (OE) of three-week old mice to identify genes enriched in the horizontal basal cells.
Project description:Wild-type horizontal basal cells (HBCs) from mouse olfactory epithelium were profiled using single-cell ATAC-seq (10x Genomics v2) to identify regions of accessible chromatin in individual cells before and 24 hours after acute injury.
Project description:The Vomeronasal organ (VNO) is a part of the accessory olfactory system, which is responsible for detecting pheromones, chemical factors that trigger a spectrum of sexual and social behaviors. The vomeronasal epithelium (VNE) shares several features with the epithelium of the main olfactory epithelium (MOE). However, it is a distinct neuroepithelium populated by chemosensory neurons that differ from the olfactory sensory neurons (OSNs) in cellular structure, receptor expression, and connectivity. The vomeronasal organ of rodents comprises a sensory epithelium and a thin nonsensory epithelium that morphologically resembles the respiratory epithelium. Sox2-positive cells have been previously identified as the stem cell population that gives rise to neuronal progenitors in MOE and VNE. In addition to these, the MOE also comprises p63 positive horizontal basal cells (HBCs), a second pool of quiescent stem cells that become active in response to injury. Immunolabeling against the transcription factor p63, Keratin-5 (Krt5), Krt14 and Krt5Cre tracing experiments highlighted the existence of horizontal basal cells distributed along the basal lamina of the VNO forming from progenitors along the basal lamina oft the marginal zones. Moreover, these experiments revealed that the NSE of rodents is, like the respiratory epithelium, a stratified epithelium where the p63/Krt5+ basal cells self-replicate and give rise to the apical columnar cells facing the lumen of the VNO.
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
Project description:The lineage of the horizontal basal cells (HBC) stem cells and their descendants from the olfactory epithelium were profiled by single-cell RNA-Seq to identify differentiated cell types, intermediate stages, transition states, and to infer the lineage trajectories.
Project description:The lineage of the horizontal basal cells (HBC) stem cells and other Sox2eGFP-positive cells from the olfactory epithelium were profiled by single-cell RNA-Seq to identify differentiated cells types, intermediate stages, transition states, and to infer the lineage trajectories.
