Project description:To investigate the CD140a+ mesenchymal cell heterogeneity in the lung in both steady and tumor-bearing conditions, we utilized CD140aEGFP reporter mice, and purified CD140a+ lung mesenchymal cells from naive and tumor-bearing mice and performed scRNA-seq.
Project description:To investigate the heterogeneity of lung CD140a+ mesenchymal cells (fibroblasts) and identify the specific lung fibroblast subset, we purified CD140a+ lung cells using CD140a-EGFP reporter mice for a higher-resolution scRNA-seq.
Project description:To determine the effect of tumor-bearing vs. host neutrophilic inflammation on reinforcement of lung neutrophil-specific immunosuppressive function, we performed single-cell RNA sequencing (scRNA-seq) on BM, PB and lung neutrophils isolated from naïve (C57BL/6J), AT3, and AT3-gcsf tumor-bearing mice.
Project description:To gain a better understanding of the role of Interleukin-1β (IL-1β) in lung CD140a+ mesenchymal cells (fibroblasts) modulation, we performed RNA-seq to compare the transcriptomes of IL-1β-treated and control lung CD140a+ mesenchymal cells (fibroblasts).
Project description:Glial progenitor cells (GPCs) pervade the human brain. These cells express gangliosides recognized by MAb A2B5, and some but not all can generate oligodendrocytes. Since some A2B5+ GPCs express PDGFa receptor (PDGFRa), which is critical to oligodendrocyte development, we asked if PDGFRa-directed sorting might isolate oligodendrocyte-competent progenitors. We used FACS to sort PDGFRa+ cells from the second trimester fetal human forebrain, based on expression of the PDGFRa epitope CD140a. CD140a+ cells could be maintained as mitotic progenitors that could be instructed to either oligodendrocyte or astrocyte phenotype. Transplanted CD140a+ cells robustly myelinated the hypomyelinated shiverer mouse brain. Microarray confirmed that CD140a+ cells differentially expressed PDGFRA, NG2, OLIG1/2, NKX2.2 and SOX2. Some expressed CD9, thereby defining a CD140a+/CD9+ fraction of oligodendrocyte-biased progenitors. CD140a+ cells differentially expressed genes of the PTN-PTPRZ1, wnt, notch and BMP pathways, suggesting the interaction of self-renewal and fate-restricting pathways in these cells, while identifying targets for their mobilization and instruction.
Project description:To determine how neutrophils are reprogrammed by lung CD140a+ MCs (mesenchymal cells), we employed lung CD140a+ MCs, and ex-vivo cultured with BM(bone marrow)-derived neutrophils. After the treatment, neutrophils were harvested for RNA extraction and the transcriptional profiles were analyzed by RNA sequencing (RNA-seq).
