Single cell RNA sequencing of Hic1 and PDGFRa-labeled cells in the heart

ABSTRACT: The cardiac stroma contains multipotent mesenchymal progenitors. However, lineage relationships within cardiac stromal cells are poorly defined. Here, we identify heart-resident PDGFRa+ SCA-1+ cells as cardiac Fibro/Adipogenic Progenitors (cFAPs) and show that they respond to ischemic damage by generating SCA-1- fibrogenic cells. Pharmacological blockade of this differentiation step with an anti-fibrotic tyrosine kinase inhibitor decreases post-myocardial infarction (MI) remodeling and leads to improvement in heart function.

Transcriptional profile of PDGFRa+ Sca-1+ and Sca-1- cells at steady state and at 7, 14 and 28 days post LAD ligation

PDGFRA Defines the Mesenchymal Stem Cell Kaposi’s Sarcoma Progenitors by Enabling KSHV Oncogenesis in an Angiogenic Environment [ChIP-seq]

Project description:Kaposi’s sarcoma (KS) is an AIDS-defining cancer caused by the KS-associated herpesvirus (KSHV). Unanswered questions regarding KS are its cellular ontology and the conditions conducive to viral oncogenesis. We identify PDGFRA(+)/SCA-1(+) bone marrow-derived mesenchymal stem cells (Pα(+)S MSCs) as KS spindle-cell progenitors and found that pro-angiogenic environmental conditions typical of KS are critical for KSHV sarcomagenesis. This is because growth in KS-like conditions generates a de-repressed KSHV epigenome allowing oncogenic KSHV gene expression in infected Pα(+)S MSCs. Furthermore, these growth conditions allow KSHV-infected Pα(+)S MSCs to overcome KSHV-driven oncogene-induced senescence and cell cycle arrest via a PDGFRA-signaling mechanism; thus identifying PDGFRA not only as a phenotypic determinant for KS-progenitors but also as a critical enabler for viral oncogenesis.

Single-cell RNA-seq of Pdgfra+/Sca1+/Cd31- mouse cardiac cells

Project description:Adult mice hearts contain a population of resident mesenchymal stem cell (MSC)-like cells called cardiac colony forming units-fibroblast (cCFU-F). The cCFU-F are housed in a population of non-muscle cardiac cells that are Pdgfra+/Sca1+/Cd31- (S+P+ fraction). The goal of this experiment was to profile the heterogeneity of cell sub-types contained within the S+P+ fraction. We profiled two replicates of S+P+ single-cell transcriptomes from the cardiac ventricles of adult, male, C57BL/6J mice after FACS sorting for live Pdgfra+/Sca1+/Cd31- non-myocyte cells.

Changes of miRNAs during osteogenic differentiation of PDGFRa+ mesenchymal progenitors derived from human skeletal muscle

Project description:Comprehensive analyses of miRNAs expression were performed using miRNA microarrays during osteogenic differentiation of PDGFRa+ mesenchymal progenitors isolated from human skeletal muscle to identify miRNAs that are involved in osteogenesis of PDGFRa+ mesenchymal progenitors. PDGFRa+ mesenchymal progenitors were isolated from the gluteus medius muscles of two different patients, and then subjected to osteogenic induction. Expression of miRNAs was examined using miRNA microarrays at the time points of one week and two weeks after osteogenic induction and were compared with that of uninduced cells.

Effects of PDGFRa-lineage leukocyte extravasation to skin in atopic dermatitis

Project description:The circulating leukocyte population contains a fraction of cells derived from progenitors that had transient PDGFRa expression during embryonic development (PDGFRa-lineage). During inflammation, extravasated leukocytes in inflamed tissue modify the tissue-resident leukocyte population and crosstalk with the stromal cells. The current study investigates the effects of extravasated leukocytes derived from PDGFRa-lineage origin on the skin in atopic dermatitis (AD). Lineage- bone marrow progenitors were isolated from PDGFRa-lineage labeling mice which labels cells derived from PDGFRa-lineage with tdTomato. Progenitors derived from PDGFRa-lineage or non-PDGFRa-lineage were transplanted to irradiated EGFP-transgenic mice and allowed for bone marrow reconstitution (BMT). AD was then induced by repeated topical application of MC903 for six times. On day 14, RNA was isolated from inflamed skin to construct library for bulk RNA sequencing. AD skin transcriptomes of PDGFRa-lineage and non-PDGFRa-lineage BMTs were compared. In addition, the obtained dataset were paired with flow cytometric measurement of leukocyte extravasation to compare samples with similar extravasation loads. We found via functional enrichment analyses that extravasated PDGFRa-lineage leukocytes possess intrinsic properties that differ from non-PDGFRa-lineage, coordinate stronger inflammatory responses and modulate the extracellular matrix.

The single cell RNA seq of PDGFRa-GFP+ cells in mouse lung

Project description:Pdgfra-expressing (Pdgfra+) cells have been implicated as progenitors in many mesenchymal tissues. To further characterize Pdgfra+ cells during alveologensis, we performed single-cell RNA sequencing (scRNA-Seq) analysis using fluorescence-activated cell sorting (FACS) sorted GFP+ cells from Pdgfra-GFP lungs at P7 and P15.
