Single cell ATAC sequencing profile of quiescent mesenchymal progenitors

ABSTRACT: After tissue injury mesenchymal progenitor subsets undergo a transient proliferative expansion, morphological transition and migration from their perivascular niche. Some of these subsets contribute enduring populations to connective tissue structures adjacent to muscle. To gain insights into gene accessibility to complement the single cell RNA seq expression data previously obtained and to uncover the lineage potential of MPs in this context, tdTomato positive cells were profiled by single cell ATAC sequencing.

Single cell RNA sequencing time-course of mesenchymal progenitors during regeneration after notexin induced muscle injury

Project description:After tissue injury mesenchymal progenitors undergo a transient proliferative expansion, morphological transition and migration from their perivascular niche. To gain transcriptomic insights into the MP function in regeneration, a muscle-injury model was employed to activate MPs and follow their contribution to tissue regeneration. To compliment the population RNA seq profile previously obtained and to uncover the suspected heterogeneity of MPs in this context, tdTomato positive cells from selected timepoints were profiled by single cell RNA sequencing.

RNA sequencing time-course of mesenchymal progenitors during regeneration after notexin induced muscle injury

Project description:After tissue injury mesenchymal progenitors undergo a transient proliferative expansion, morphological transition and migration from their perivascular niche. To gain transcriptomic insights into the transition of MPs out of the quiescent state and their role in muscle regeneration, a muscle-injury model was used to activate MPs and follow their contribution to tissue regeneration. tdTomato positive MPs were FACS purified from dissociated muscle at different time points after notexin-induced injury and transcriptomic analysis was performed using RNA sequencing of all samples.

Single cell RNA-sequencing of inguinal adipose tissue Pdgfrβ+ cells

Project description:We previously derived a doxycycline-inducible (Tet-On) lineage-tracing model that allows for the indelible labeling of Pdgfrb-expressing perivascular cells in adipose tissue of adult mice (PdgfrbrtTA; TRE-Cre; Rosa26RmT/mG; herein, MuralChaser mice). Prior to exposing animals to doxycyline, all cells within the stromal-vascular fraction (SVF) of adult inguinal WAT (iWAT) express membrane tdTomato from the Rosa26 locus. Following 9 days of exposure to doxycycline-containing chow diet, Cre-mediated excision of the loxP-flanked tdTomato cassette occurs in Pdgfrb-expressing cells, and membrane-bound GFP (mGFP) expression is constitutively activated. We set out to test the hypothesis that Pdgfrb-expressing perivascular cells in inguinal WAT of adult mice are heterogeneous, with subpopulations harboring functionally distinct phenotypes. To this end, we performed single cell RNA-sequencing of mGFP+ cells isolated from iWAT of lean (chow fed) 8 weeks-old male MuralChaser mice following 9 days of doxycycline exposure.

Single cell RNA-sequencing of visceral adipose tissue Pdgfrβ+ cells

Project description:We previously derived a doxycycline-inducible (Tet-On) lineage-tracing model that allows for the indelible labeling of Pdgfrb-expressing perivascular cells in adipose tissue of adult mice (PdgfrbrtTA; TRE-Cre; Rosa26RmT/mG; herein, “MuralChaser mice”). Prior to exposing animals to doxycyline, all cells within the stromal-vascular fraction (SVF) of adult gonadal WAT (gWAT) express membrane tdTomato from the Rosa26 locus. Following 9 days of exposure to doxycycline-containing chow diet, Cre-mediated excision of the loxP-flanked tdTomato cassette occurs in Pdgfrb-expressing cells, and membrane-bound GFP (mGFP) expression is constitutively activated. We set out to test the hypothesis that Pdgfrb-expressing perivascular cells in gonadal visceral WAT of adult mice are heterogeneous, with subpopulations harboring functionally distinct phenotypes. To this end, we performed single cell RNA-sequencing of mGFP+ cells isolated from gWAT of lean (chow fed) 8 weeks-old male MuralChaser mice following 9 days of doxycycline exposure.

Whole transcriptome analysis of FACS purified somatosensory neuron subtypes and whole dorsal root ganglia tissue

Project description:The goal of this study was to analyze global gene expression in specific populations of somatosensory neurons in the periphery, including major, non-overlapping populations that include nociceptors, pruriceptors, and prorioceptors. The mammalian somatosensory nervous system encodes the perception of specific environmental stimuli. The dorsal root ganglion (DRG) contains distinct somatosensory neuron subtypes that innervate diverse peripheral tissues, mediating the detection of thermal, mechanical, proprioceptive, pruriceptive, and nociceptive stimuli. We purified discrete subtypes of mouse DRG somatosensory neurons by flow cytometry using fluorescently labeled mouse lines (SNS-Cre/TdTomato, Parv-Cre/TdTomato) in combination with Isolectin B4-FITC surface staining (IB4). This allowed identification of transcriptional differences between these major populations, revealing enrichment of voltage-gated ion channels, TRP channels, G-protein coupled receptors, transcription factors, and other functionally important classes of genes within specific somatosensory neuron subsets. SNS-Cre mice were bred with Rosa26-TdTomato mice to generate SNS-Cre/TdTomato reporter mice. Parv-Cre mice were bred with Rosa26-TdTomato mice to generate Parv-Cre/TdTomato mice. Isolectin B4-FITC was used to stain the surface of SNS-Cre/TdTomato reporter mice. We used these strategies of fluorescent labeling to purify distinct murine sensory neuron subsets from the dorsal root ganglia (DRG) by fluorescence activated cell sorting (FACS). Neurons were sorted directly in Qiazol for total RNA extraction and microarray analysis. Whole DRG tissue was also included for transcriptome analysis to compare with purified neuronal populations.

YAP Drives Assembly of a Spatially Colocalized Cellular Triad Required for Heart Renewal

Project description:After myocardial infarction (MI), the heart fails to renew, and the cardiac microenvironment is irreversibly disrupted. Inactivation of the Hippo signaling pathway can rebuild the post ischemic microenvironment and improve cardiac function. We investigated spatially resolved cellular relationships of neonatal and adult renewal-competent hearts to gain insight into inefficient mammalian heart renewal. Spatial transcriptomics (ST) and single-cell sequencing of adult control hearts and hearts expressing YAP5SA, an active version of the Hippo signaling pathway effector YAP, which models heart renewal, revealed a conserved, renewal-competent cardiomyocyte (CM) population in control hearts and amplified in YAP5SA hearts. This CM population was also found in the wildtype, renewal competent neonatal heart after myocardial infarction, as well as the adult human heart. Cardiac fibroblasts (CFs), expressing complement C3, colocalized with these CMs. In YAP5SA hearts and neonatal hearts post-MI, macrophages (MPs) expressing complement receptor C3ar1 also colocalized, creating a pro-renewal niche composed of the CM, CF and MP triad. Both C3 and C3ar1 loss-of-function in YAP5SA hearts similarly suppressed heart renewal, indicating that C3-expressing CFs, C3ar1-expressing MPs, and complement system signaling play a direct role in heart renewal

Distinct mesenchymal lineages and niches promote epithelial self-renewal and myofibrogenesis in the lung

Project description:Using flourescence activated cell sorting, we gated on cells negative for CD45, CD326 and CD31, from single cell suspension generated from Adult mice. We then isolated subsets of YFP-, GFP- or TdTomato expressing cells from the indicated reporter mice. tdTomato indicates Wnt-responsive cells, GFP reports Pdgfr-alpha expression and YFP- was used to isolate lineaged Wnt2-positive cells. Additionally we included cells that were negative for the aforementioned reporters. We performed RNAseq on biological duplicates for each subset.

Transcriptomic profiling of immune and stromal cells from the non small cell lung cancer (NSCLC) environment

Project description:T lymphocytes can efficiently counteract the growth of tumors within the tumor microenvironment. Specialized immune-interacting fibroblasts, termed fibroblastic reticular cells (FRC) are responsible for the formation of specialized niches promoting immune cell activation in secondary lymphoid organs and originate from embryonic progenitors. FRCs have also been identified in tertiary lymphoid structures (TLS) in tumor tissues. However, the identity and differentiation of TLS-associated FRC subsets that promote intra-tumoral T cell activity have remained unexplored. Here, we employed single cell RNA-sequencing of fibroblasts and immune cells, sampled from subpleural margin, central margin and unaffected lung tissue in non small cell lung cancer (NSCLC), demonstrating the formation of specific tumor T cell environments (TTEs) underpinned by CCL19-expressing FRCs. We detected tumor-specific FRC subsets namely CCL19-expressing TRCs and perivascular reticular cells (PRCs) interacting with intratumoral T cells, and thus regulating FRC differentiation and T cell activation. Our results highlight a remarkable functionality of FRCs to efficiently determine protective antitumoral T cell responses in NSCLC.
