Single-cell RNA sequencing characterizes the comparision between Granulocyte-colony stimulating factor (G-CSF) primed human bone marrow and unstimulated bone marrow

ABSTRACT: Purpose: The goal of the study is to obatin a comprehensive landscape of G-CSF primed bone marrow (G-BM) and to deciphering the underlying mechanisms of immune modulatory effect induced by G-CSF treatment. Methods: We recruited two healthy donors and treated them with recombinant G-CSF at a dosage of 5μg/kg body weight per day for 5 consecutive days. The bone marrow samples were collected by aspiration on the fourth day of G-CSF treatment. Bone marrow samples from healthy donors were treated with lysing solution to remove erythrocytes and were then labeled with antibodies. Through flow sorting, the final cells used for single-cell RNA sequencing (scRNA-seq) contained CD45+CD66b- population (90%), CD66b+ population (5%), and CD45- population (5%). Results and Conclusion: Through unbiased analysis, our data systematically showed the alterations in the transcriptional landscape of hematopoietic cells in G-BM, and illustrated the mechanisms of hyporesponsiveness of T cells and natural killer (NK) cells caused by G-CSF stimulation.

Mouse bone marrow derived macrophages

Project description:Bone marrow cells (BM) were isolated and primed with M-CSF (M BMDM) or GM-CSF (GM BMDM) for 7 days. M-BMDMs were treated with IL6 (20 ng/ml) for 3 h or 24 h while GM-BMDMs were treated for 3 h. The difference between BM, M-BMDM, and GM-BMDM were analyzed to describe the phenotye and function of each population. Moreover, by RNA-seq analysis, the influence of IL6 treatment on GM-BMDMs and M-BMDMs were analyzed.

Expression data of colony-stimulating factor (CSF) grown bone marrow derived cells

Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM). Bone marrow cells were differentiated for 7 days with 25 ng/ml GM-CSF or 20% L cell conditioned media as a M-CSF supplier. GM-BMDCs were sorted from MHCIIhighF4/80low population and GM-BMMs were sorted in the MHCIIlowF4/80high population. M-BMMs were sorted from CD11b+F4/80+ population.

Modulating Bone Marrow Hematopoietic Lineage Potential to Prevent Breast Cancer Bone Metastasis

Project description:The presence of disseminated tumor cells in patient bone marrow (BM) aspirates predicts decreased recurrence-free survival, yet little is known about whether hematopoietic BM cells impact bone metastases. Here, we report that the BM can be rendered metastasis-suppressive by the bone-targeting bisphosphonate, zoledronic acid (ZA). In particular, ZA modulates hematopoietic myeloid/osteoclast progenitor cell (M/OCP) lineage potential to render them metastasis-suppressive. Granulocyte-colony stimulating factor (G-CSF) promotes resistance to ZA by re-directing M/OCP differentiation. We identified BM transcriptional programs that associate with metastasis suppression and resistance to ZA. Analysis of patient blood samples taken at randomization revealed that women with plasma G-CSF levels >23 pg/mL experienced significantly worse outcome with adjuvant ZA than those on ZA who had lower plasma G-CSF levels. Our findings establish that hematopoietic cells and M/OCP lineage potential profoundly impact bone metastasis and support the discovery of biomarkers that stratify therapeutic responses in patients at risk of recurrence.

Gene expression profile at the single cell level of CD45+ CD11b+ cells isolated from the brain and bone marrow of mice either untreated or conditioned and transplanted with total bone marrow.

Project description:We used single-cell RNA sequencing (scRNA-seq) to analyze the diversity of bone marrow-derived CD45+CD11b+ microglia-like cells (MGLCs) engrafted in the brain of recipient mice that were conditioned using Busulfan and PLX3397 and transplanted with total bone marrow. We compared the gene expression of MGLCs to that of developmentally-derived CD45+ CD11b+ microglia/myeloid cells isolated from the brain of recipient mice (host microglia) and untreated mice (naive microglia). We also compared the gene expression of MGLCs to that of transplant-derived CD45+ CD11b+ cells engrafted in the bone marrow (abbreviated as BM-CD11b+)

Global miRNA Expression of Bone Marrow Mesenchymal Stem/Stromal Cells in Fanconi Anemia Patients Before and After Bone Marrow Transplantation, and their Allogeneic Bone Marrow Donors

Project description:Fanconi anemia (FA) is a rare genetic disorder characterized by genomic instability, developmental defects and bone marrow failure. Homeostasis of hematopoietic stem cells (HSCs) in the bone marrow partly relies on their direct or indirect interactions with the mesenchymal stem/stromal cells (MSCs). miRNAs can play a critical role during these interactions. There is no study available so far addressing the miRNA profile of bone marrow (BM-) MSCs in FA disease state. Non-coding RNA expression profiling was performed in BM-MSCs obtained from Donors (siblings of FA patients) as well as FA patients before (preBMT) and after bone marrow transplant (postBMT) using GeneChip miRNA 2.0 Array. Quality Control (QC) was performed via Normalized Unscaled Standard Errors (NUSE) and Relative Log Expression (RLE) before further analysis.

Human bone marrow precursor cells

Project description:The aim of this study was to characterize in vivo miRNA expression in normal myeloid development of the neutrophil granulocyte (granulopoiesis) to gain insight into miRNA control of these processes. Cell populations highly enriched in precursors from successive stages of granulopoiesis and mature neutrophils were isolated from bone marrow (BM) and peripheral blood (PB) samples, respectively, from 4 healthy human donors. Total RNA was extracted from each cell population and subjected to miRNA gene expression profiling using miRCURYTM LNA microRNA Arrays

Identification of a CD117+ CD71+ early unipotent neutrophil progenitor population in human bone marrow

Project description:Neutrophils play critical roles in health and disease. Due to their very short half-life in blood and tissue, neutrophils are constantly replenished by bone marrow progenitors. Thus, a comprehensive understanding of bone marrow neutrophil development is of paramount importance to identify how neutrophil production is altered in disease. Recently, two novel human neutrophil progenitor populations were identified; ‘human neutrophil progenitor’ or ‘hNeP’ (Lin- CD66b+ CD117+ ) and ‘neutrophil precursor’ or ‘preNeu’ (Lin- CD66b+ CD15+ CD49d+ ). How these subsets fit into the neutrophil lineage is unclear. By using mass and flow cytometry, we show that hNeP are a heterogenous population containing a homogeneous progenitor subset termed ‘early neutrophil progenitor’ or ‘eNeP’ (Lin- CD66b+ CD117+ CD71+ ). Surface marker and RNA expression, together with the ability to form colonies in vitro and exclusively produce neutrophils in vivo in humanized NSG-SGM3 mouse transfer experiments indicate that eNeP are hierarchically the ‘earliest’ cells within preNeu. eNeP constitute ~0.14% of human bone marrow neutrophils, while preNeu constitute ~5% of bone marrow neutrophils. Furthermore, we have identified CD71 as a novel neutrophil surface marker associated with distinct early neutrophil developmental stages. Intriguingly, CD71+ characterizes proliferating neutrophils, which are expanded in the blood of melanoma and lung cancer patients and detectable in human lung tumors. Collectively, our findings i) identify CD117+ CD71+ eNeP as an early neutrophil progenitor population, ii) introduce a unified model of human neutrophil bone marrow development, iii) identify novel surface markers for distinct neutrophil developmental stages and iv) provide evidence for neutrophil progenitor expansion in cancer.

Human bone marrow comprise atypical adipocytes with specific lipid metabolism

Project description:Under caloric restriction, bone marrow adipocytes (BM-Ad) do not decrease in size conversely to white adipocytes, suggesting their unique metabolic properties. We compared human primary BM-Ad with paired subcutaneous adipocytes (SC-Ad) using proteomic and lipidomic approaches. We found that while SC-Ad and BM-Ad share similar morphological features, they possess distinct lipid metabolism. BM-Ad shows enrichment in proteins involved in cholesterol metabolism correlating with increased free cholesterol content while proteins involved in lipolysis were downregulated. In particular, monoacylglycerol lipase expression was strongly reduced in BM-Ad, leading to accumulation of monoacylglycerol. Consequently, basal and induced lipolytic responses were absent in BM-Ad, affirming their differences in metabolic fitness upon caloric restriction. These specific metabolic features are not recapitulated in vitro using common protocols to differentiate bone marrow mesenchymal stem cells. Thus, contrary to classical SC-Ad, BM-Ad display a specific lipid metabolism, as they are devoid of lipolytic activity and exhibit a cholesterol-orientated metabolism.
