Gene expression data from mouse tracheal epithelial cells isolated before and 48hrs after SO2 injury

ABSTRACT: The conducting airway epithelium of the rodent and human lung is made up of about equal proportions of ciliated and secretory cells. In addition, in regions where the epithelium is pseudostratfied, ~30% of the epithelium consists of undifferentiated basal cells (BCs). Evidence suggests that these BCs are multipotent stem cells that can self renew over the long term and give rise to both ciliated and secretory lineages. The goal of this project is to identify cellular and molecular mechanisms by which the basal cells normally maintain the epithelium and repair it after injury. We used Affymetrix microarray analysis to compare transcripts in tracheal epithelium before and after SO2 injury. Mice tracheal epithelium and mesenchyme were separate for RNA extraction before and 48hrs after SO2 injury. Cells from tracheas of 4 male C57Bl/6 mice were pooled for each biological experiment. The experiments were repeated three times for triplicate samples.

Gene expression data from mouse tracheal mesenchymal cells before and 48hrs after SO2 injury

Project description:The conducting airway epithelium of the rodent and human lung is underlaid by mesenchymal cells that include vasculature, smooth muscle, fibroblasts and cartilage. The goal of this project is to identify cellular and molecular changes in the mesenchyme after injury to the epithelium by exposure to SO2 and which may participate in repair of the epithelium We used Affymetrix microarray analysis to compare transcripts in tracheal mesenchyme before and after SO2 injury. Mice tracheal epithelium and mesenchyme were separate for RNA extraction before and 48hrs after SO2 injury. Sample from 4 mice were pooled for each biological experiment. The experiments were repeated three times for triplicate samples.

Single cell RNA sequencing of normal endometrial derived organoids uncovers novel cell type markers for prognostication

Project description:Endometrial carcinoma, the most common gynecologic cancer, develops from endometrial epithelium which is composed of secretory and ciliated cells. Pathologic classification is unreliable and there is a need for prognostic tools. We used single cell sequencing to study organoid model systems derived from normal endometrial endometrium to discover novel markers specific for endometrial ciliated or secretory cells. We performed single cell sequencing on endometrial and ovarian tumors and found both secretory-like and ciliated-like tumor cells.

Activation of Notch1 and Notch3 Skews Human Airway Basal Cell Differentiation Toward a Secretory Pathway

Project description:Airway basal cells (BC) function as progenitor cells capable of differentiating into ciliated and secretory cells to replenish the airway epithelium during physiological turnover and repair. The objective of this study was to define the role of Notch signaling in regulating human airway BC differentiation into a pseudostratified mucociliated epithelium. Notch inhibition with γ-secretase inhibitors demonstrated Notch activation is essential for BC differentiation into secre-tory cells and ciliated cells, but more so for the secretory lineage. Sustained Notch activation via lentivirus expression of the intracellular domain of each Notch receptor (NICD1-4) demonstrated that the Notch 2 and 4 pathways have little effect on BC differentiation, while activation of the Notch1 or 3 pathways has a major influence, with persistent expression of NICD1 or 3 resulting in a skewing toward secretory cell differentiation with a parallel decrease in ciliated cell differentiation. These observations provide insights into the control of the balance of BC differentiation into the secretory vs ciliated cell lineage, a balance that is critical for maintaining the normal function of the airway epithelium in barrier defense against the inhaled environment. Array-based expression profiling of the Notch signaling pathway genes specifically in human airway basal cells.

Pathologic classification is unreliable and there is a need for prognostic tools. We used single cell sequencing to study organoid model systems derived from normal endometrial endometrium to discover novel markers specific for endometrial ciliated or secretory cells. We performed single cell sequencing on endometrial and ovarian tumours, and on organoids both treated with DBZ and normal and found both secretory-like and ciliated-like tumour cells.

JAG1 Mediated Notch Signaling Regulates Secretory Cell Differentiation of the Human Airway Epithelium

Project description:Background: Basal cells (BC) are the stem/progenitor cells of the human airway epithelium capable of differentiating into secretory and ciliated cells. Notch signaling activation increases BC differentiation into secretory cells, but the role of individual Notch ligands in regulating this process is unknown Results: The objective of this study was to define the role of the Notch ligand JAG1 in regulating BC differentiation. JAG1 over-expression in BC increased secretory cell differentiation, with no effect on ciliated cell differentiation. Conversely, knockdown of JAG1 decreased expression of secretory cell genes. Conclusions: These data demonstrate JAG1 mediated Notch signaling regulates differentiation of BC into secretory cells. This study demonstrates that expression of the Notch ligand JAG1 is highly enriched in basal stem/progenitor cells (BC) of the human airway epithelium and that modulation of its expression levels during differentiation of BC play an important role in regulating secretory cell differentiation with no effect on ciliated cell differentiation. These observations have implications for developing novel targets to specifically modulate levels of secretory cells in human airway disorders.

miRNAs high throughput sequencing profiling of basals cells and columnar cells

Project description:The airway mucociliary epithelium is consituted of three main cell types : columnar ciliated plus secretory cells and basal cells. Columnar cells are represented by a great majority of ciliated cells. We used Cell sorting by FACSaria to separate basal cells from ciliated and secreting columnar cells. Then, we performed microRNA high throughput sequencing to investigate the specific signature of microRNA of basal and columnar cells. miRNAs high throughput sequencing profiling of human nasal mucosa: basals cells (B) and columnars (C) cells for 3 donors.
