Single cell RNA-seq of 3 key time points in oesophageal post-natal development

ABSTRACT: The purpose of this single cell experiment is to compare and characterize at molecular level oesophageal epithelial cells at different points in post-natal development (post-natal day 7 and 28) and at the onset of homeostasis (over p70). With the aim of identifying differences in timepoints showing the key molecular markers of the transition from a rapidly expanding tissue to one that is stable in size and function. Previous data has suggested this transition point occurs around P28 and we hope to see here a similarity in the profile of P28 samples with that of adults. Single cell suspensions of pooled oesophageal epithelial and stroma cells were sorted for EpCam+ and CD45- expression to select for epithelium cells for RNA-sequencing.

Epithelial cells rapidly adapt their behaviour in response to increasing tissue demands. However, the processes that finely control these cell decisions remain largely unknown. The postnatal period covering the transition between early tissue expansion and the establishment of adult homeostasis provides a convenient model with which to explore this question. Here, we demonstrate that the onset of homeostasis in the epithelium of the mouse oesophagus is guided by the progressive build-up of mecha ...[more]

Changes in miRNA expression in mouse primary visual cortex following visual deprivation

Project description:Visual deprivation, either in the form of dark rearing (DR) or monocular deprivation (MD) are established paradigms for studying cortical plasticity. We have used miRNA microarray to uncover miRNAs whose expression is altered in primary visual cortex following DR and/or MD. C57BL6 mice were reared in normal light and dark conditions (control) till P28, in complete darkness since birth (DR) till P28, or were grown in normal light/dark conditions from birth till P24 and then subjected to lid suturing of one eye till P28. Mice were euthanized at P28 and their primary visual cortex areas were excised and subjected to RNA isolation. In the case of MD mice only the contralateral to lid suture primary visual cortex was extracted. 100ng of total RNA (tested and quantified using the Agilent Bioanalyzer 2100) were labeled using the Agilent miRNA labeling system and hybridized to Agilent murine miRNA arrays. Microarrays were hybridized overnight at 64 ºC, scanned using an Agilent scanner and extracted with Agilent feature extractor 10.1.

Age-dependent gene and protein expression following transection of neonatal spinal cord of Monodelphis domestica (South American Grey Short-tailed opossum)

Project description:In the present study we investigated the genome and the proteome in the segment of cord rostral to the site of injury following a complete spinal cord transection in opossums at an age when axonal growth across a lesion and substantially normal locomotor development occur (postnatal day 7, P7) and compared this with an older age when no axon growth can be seen, but nevertheless a demonstrable body weight-bearing locomotion is present (P28, Wheaton et al, 2011). 7 RNA-seq samples, consisting of 2 biological replicates of controls at day 8, 1 control sample at day 29, and 2 biological replicates each from injured animals at days 8 and 29.

Dmrt1 (doublesex and mab-3 related transcription factor 1) conditional knockout expression analysis of P28 testes

Project description:Dmrt1 (doublesex and mab-3 related transcription factor 1) is a conserved transcriptional regulator of male differentiation required for testicular development in vertebrates. This study examines the result of conditional removal of Dmrt1 from Sertoli cells in P28 testis tissue. Testes from P28 Dmrt1 flox/flox mice were compared to testes from P28 Dmrt1 flox/flox mice with the Sertoli cell-specific Sf1 (Nr5a1; MGI:1346833) or Dhh (MGI:94891) promoters driving Cre expression.

Charting the age-altered thymic epithelial cell differentiation by lineage tracing from a beta 5-t expressing TEC progenitor

Project description:TEC progenitors that express beta 5-t contribute to both the cortical and medullary TEC compartments. Our initial experiments across ageing thymi identified a population of potential progenitor TECs which expanded with age, and appears to be a progenitor population for mTEC. These lineage tracing experiments are designed to chart the altered differentiation and senescence of mTEC progenitors with age.

Cellular plasticity and diversity during heart valve epithelial-to-mesenchymal transitions revealed using single-cell RNA-seq

Project description:We have generated scRNA-seq data from embryonic day (E)10.5 and E12.5 atrioventricular canals (primitive heart valves) to assess cellular diversity during the distinct epithelial-to-mesenchymal transitions (EMTs) from endocardium and epicardium that guide the formation of valve mesenchyme. Alongside, wildtype atrioventricular canals, we generated scRNA-seq data from Sox9 conditional knockouts (Sox9fl/fl;Tie2-cre) to explore the role of SOX9 in EMT. Atrioventricular canals were microdissected from cardiac chambers and outflow tract, enriching for heart valve progenitor lineages.

The Fly Cell Atlas: single-cell transcriptomes of the entire adult Drosophila - 10x dataset

Project description:Single-cell technologies have ushered in a new era for Drosophila research, allowing researchers to obtain transcriptomes for all stable cell types and dynamic cell states. Here we present the first release of the adult Fly Cell Atlas (FCA), which includes 580k cells from 15 individually dissected sexed tissues, as well as from the entire head and body. We annotated more than 250 distinct cell types across all tissues. Few cell types were uniquely detected in the entire head and body samples, suggesting high cell-type saturation. We provide an in-depth analysis of gene signatures and transcription factor combinations, as well as sexual dimorphism, across the whole animal. Finally, we studied cell type lineages that are shared between tissues, such as blood cells and muscle cells, allowing the retrieval of rare cell types and tissue- specific subtypes. This atlas provides a valuable resource for the entire Drosophila community as a reference to study genetic perturbations and disease models at single-cell resolution.

Single cell sequencing analysis of senescence in Mus musculus prostate cancer models

Project description:Acute Pten loss initiates prostate tumorigenesis characterized by cellular senescence response. Here we examine the cellular senescence response in epithelial individual cells, by single-cell RNA sequencing (scRNAseq) in Ptenpc-/- and Ptenpc-/-; Timp1-/- GEMMs. ScRNAseq analysis determines a cluster of senescent cells expressing the senescence-related genes. A significant positive correlation is observed between the senescence score and Bcl2 expression. This provides the rational for targeting senescent cells using Bcl2 inhibitor.
