Project description:Single cell RNA-Seq experiment was conducted using mouse olfactory epithelia at E18.5, P14, and adult stage to study the gene expression in different cell types, including olfactory sensory neurons and their progenitor cells.
Project description:A series of RNA-Seq experiment were conducted to study the transcriptome changes of olfactory sensory neurons during the critical period. We conducted RNA-seq of the olfactory epithelia at P0, P3, P7, P14, and P21 to identify the gene expression changes in the olfactory epithelia. We also performed RNA-Seq experiment of the olfactory epithelia from Kir2.1 transgenic mice at the same time points to understand the effect of neural activity deprivation on the transcriptome.
Project description:KLF7 null mice show profound axonal growth defects in the olfactory epithelium. The goal of this study was the identification of potential KLF7 target genes in olfactory sensory neurons. Experiment Overall Design: Olfactory epithelia were isolated from 3 wildtype and 3 mutant 1 day old pups and the RNA isolated, labeled and hybridized to one chip each.
Project description:The goal of scRNA-seq is to explore whether olfactory sensory neurons (OSNs) that display a specific olfactory receptor (OR) express a distinct transcriptional program from OSNs that display a different OR in a large and unbias scale. Olfactory epithelial single cell suspensions were made using 3 male and 3 female mice. Single-cell sequencing libraries were prepared using Chromium Single Cell 3’ Reagent Kit V3 (10X Genomics) according to the manufacturer’s guidelines. Libraries were sequenced using 150 cycles of paired end reads on Illumina Hiseq4000 and Novaseq6000 instruments (Novogene). The sequencing reads were processed using the DolphinNext Single Cell-10X Genomics pipeline (https://dolphinnext.umassmed.edu/index.php?np=1&id=420, default settings except STAR v2.6.1 was used for alignment).
Project description:We performed single-cell RNAseq of human olfactory and respiratory epithelium and found evidence of olfactory neurogenesis and differentiation in adult humans.
Project description:We sequenced the transcriptome of 34 single olfactory sensory neurons (OSNs) manually picked from OMP-GFP mice, ensuring the cells expressed high levels of GFP, a marker of mature OSNs. We pooled the olfactory mucosa from 2 male and 2 female animals, to obtain single-cell suspensions for cell picking. We only picked healthy-looking cells. From each, we constructed libraries for single-cell RNA-sequencing, to characterise the diversity of OR genes expressed.
Project description:Purpose:The endometrium layer comprises of luminal and glandular epithelia that both develop from the same simple layer of fetal uterine epithelia. Mechanisms of uterine epithelial progenitor self-renewal and differentiation are unclear. Methods: This study aims to systematically analyze the molecular and cellular mechanisms of uterine epithelia development by single cell RNA-Seq Results: An integrated set of single cell transcriptomic data of uterine epithelial progenitors and their differentiated progenies is provided. Additionally, the unique molecular signatures of these cells, characterized by sequential up-regulation of specific epigenetic and metabolic activities, and activation of unique signaling pathways and transcription factors, were also investigated. Finally, a unique subpopulation of early progenitor, as well as differentiated luminal and glandular lineages were identified. A complex cellular hierarchy of uterine epithelia development was thus delineated. Conclusions: Our study therefore systematically decoded molecular markers and cellular program of uterine epithelia development that would shed lights on uterine developmental biology.
