Project description:Comparative genomic analysis of basal and LPS-induced expression patterns of bone marrow derived macrophages and bone marrow resident macrophages demonstrates completely divergent transcriptome profile and indicates/confirms the existance of two distinct monocyte/macrophage populations in murine bone marrow. Most resident tissue macrophages descent from embryonic precursors of the yolk sac but inflammatory and bone marrow (BM) macrophages are considered to develop from hematopoietic stem cells (HSCs) in the BM. We now identified a novel subpopulation of resident CD163+ macrophages in the BM which were phenotypically and functionally distinct from classical BM-derived macrophages. Bioinformatics analysis of transcriptoms indicated a unique immune-modulatory phenotype of CD163+ macrophages. Cell fate studies in Csf1rMer-iCre-Mer;RosaLSL-GFP mice demonstrated that resident CD163+ macrophages of the BM do not develop from HSCs but descent from embryonic progenitors in the yolk sac strictly dependent on transcription factor IRF8. In contrast to other yolk sac derived tissue macrophages CD163+ cells seem to play a relevant role in infections and sterile inflammation. IRF8-/- mice lacking this population are highly sensible to S. aureus infections. Thus, CD163 defines a macrophage population resident in the bone marrow but originating from yolk sac progenitors which exhibits immune-modulatory properties under different inflammatory conditions. We used quantitative RNA-seq to perform whole transcriptome analysis and compare the transcriptomes of resident CD163+ BM macrophages and classical CD163- BMDM in steady state and after LPS stimulation.

Project description:The bone marrow (BM) is the third most frequent site of metastasis for solid tumors, creating an unfavorable clinical outcome. It provides a unique microenvironment that promotes growth of tumors, however, the role of different BM cells, their molecular features, and their interactions with tumor cells, are poorly defined. Here, we investigate the BM niche in neuroblastoma (NB), a pediatric cancer of the sympathetic nervous system. NB has been molecularly defined at the primary cancer site, yet, the metastatic site is poorly characterized. We performed single-cell transcriptomics (scRNA-seq) and epigenomic profiling (scATAC-seq) of BM aspirates from 11 subjects spanning three major NB subtypes: patients with MYCN amplification (MNA), ATRX mutations (ATRXmut), and cases that lack these alterations (sporadic): NB cases were then compared to five age-matched and metastasis-free BM (controls), followed by in-depth single cell analyses of tissue diversity and cell-cell interactions. We present the first map of the epigenetic and transcriptomic effects of bone marrow metastases. Our analyses demonstrate that tumor cells in the metastatic niche display plasticity that differs among NB subtypes. NB cells via cell-cell interaction signal to the bone marrow microenvironment, rewiring specifically monocytes, which exhibit M1 and M2 features, marked by activation of pro- and anti-inflammatory programs, and express tumor-promoting factors, reminiscent of tumor-associated macrophages. Our study may provide the basis for a therapeutic approach, targeting tumor-to-microenvironment interactions.

Project description:To precisely identify mice resident alveolar macrophages (AMs) and bone marrow (BM)-derived macrophages, we developed a technique to separately label AMs and BM-derived macrophages with a fluorescent lipophilic dye followed by fluorescent-associated cell sorting (FACS). We utilized this approach to isolate BM-derived macrophages and AMs at different timepoints after intratracheal (IT) instillation of E.coli lipopolysaccharide (LPS) and performed bulk RNAseq on these cell populations to characterize the individual phenotypes of resident AMs and BM-derived macrophages present in the lungs.
