RNA-seq of BM neutrophils after cultured with lung CD140a+ MCs

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).

CD140a+ human glial progenitor cells

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. 10 samples, 5 CD140a+, and 5 CD140a- sorted samples for individual fetal human brain

Transcription profile of fetal human CD140a-defined OPC differentiation in vitro

Project description:Human fetal dissociates from 19-22 week gestational age were magnetically sorted for CD140a antigen. CD140a-defined OPCs were plated into serum free conditions and allowed to differentiate in the absence of growth factors or mitogens. RNA was extracted from cells immediately following isolation and every day for 4 days. To block differentiation, matched cells were cultured in the presence of PDGF-AA (10ng/ml). This treatment prevents the acquisition of O4-positive oligodendrocyte cell fate and delays MBP mRNA expression by human CD140a-sorted OPCs.

CD133/CD140a-Based Isolation of Distinct Human Multipotent Neural Progenitor Cells and Oligodendrocyte Progenitor Cells

Project description:The mechanisms underlying the specification of oligodendrocyte fate from multipotent neural progenitor cells (NPCs) in developing human brain are unknown. In this study, we sought to identify antigens sufficient to distinguish NPCs free from oligodendrocyte progenitor cells (OPCs). We investigated the potential overlap of NPC and OPC antigens using multicolor fluorescence-activated cell sorting (FACS) for CD133/PROM1, A2B5, and CD140a/PDGFaR antigens. Surprisingly, we found that CD133, but not A2B5, was capable of enriching for OLIG2 expression, Sox10 enhancer activity, and oligodendrocyte potential. As a subpopulation of CD133- positive cells expressed CD140a, we asked whether CD133 enriched bone fide NPCs regardless of CD140a expression. We found that CD133+CD140a- cells were highly enriched for neurosphere initiating cells and were multipotent. Importantly, when analyzed immediately following isolation, CD133+CD140a- NPCs lacked the capacity to generate oligodendrocytes. In contrast, CD133+CD140a+ cells were OLIG2-expressing OPCs capable of oligodendrocyte differentiation, but formed neurospheres with lower efficiency and were largely restricted to glial fate. Gene expression analysis further confirmed the stem cell nature of CD133+CD140a- cells. As human CD133+ cells comprised both NPCs and OPCs, CD133 expression alone cannot be considered a specific marker of the stem cell phenotype, but rather comprises a heterogeneous mix of glial restricted as well as multipotent neural precursors. In contrast, CD133/CD140a-based FACS permits the separation of defined progenitor populations and the study of neural stem and oligodendrocyte fate specification in the human brain.

scRNA-seq study of hippocampal microglia, perivascular macrophages and perivascular fibroblasts in pre-plaque APP-KI mice

Project description:Aim of this experiment was to characterize whether SPP1 released from the hippocampal perivascular space could imprint microglia transcriptional states. We performed scRNA-seq analysis on sorted CD140a+ perivascular fibroblast (PVF), CD45highCD11intCD206+ perivascular macrophage (PVM) and CD45intCD11intCX3CR1high microglial cell from dissected hippocampi of 6-month old wild type vs SPP1KO/KO vs AppNL-F mice vs AppNL-FxSpp1KO/KO mice. Cells were isolated from dissected hippocampi as previously described (Sala Frigerio et al.,2019).
