Paired scRNAseq of the and non-hematopoietic and the immune microenvironment of aspirates from newly diagnosed Multiple Myeloma patients versus non-cancer controls

ABSTRACT: By generating a paired single cell RNA-sequencing database of the tumor niche from 10 newly diagnosed MM patients, we created a unique dataset allowing the in-depth analyses of stromal-immune interactions within the tumor microenvironment. Using this database, we identified the presence of inflammatory stromal fibroblasts in the bone marrow of Myeloma patients.The stromal inflammation was associated with NF-κB signaling, and sources of IL-1β or TNFα were specific immune subsets previously shown to be altered in MM, suggesting the presence of an immune cell-mediated feed-forward loop of bone marrow inflammation in MM. By tracking inflammatory signatures over time in individual patients undergoing first-line treatment using bulk RNA sequencing, we show that bone marrow inflammation is not reverted by successful anti-tumor therapy (see related accession number), suggesting a role for stromal fibroblasts and bone marrow inflammation in disease persistence or relapse.

An IL-1β driven neutrophil-stromal cell axis fosters a BAFF-rich microenvironment in multiple myeloma

Project description:Neutrophils are the most abundant nucleated cell type in the bone marrow. A pro-tumor bias in this cell type may have implications for bone-marrow residing malignancies, such as multiple myeloma. Here, we generated single cell transcriptomic overviews of the entire myeloid compartment, including the entire neutrophilic lineage, of the bone marrow of 6 newly diagnosed myeloma patients, 5 treated myeloma patients and 4 non-cancer controls. We find dat mature neutrophils in myeloma patients, both newly diagnosed and treated, have an activated and pro-inflammatory phenotype, accompanied by increased transcription of pro-inflammatory cytokines, such as IL-1β, and myeloma cell survival factors, such as BCMA-ligand BAFF/TNFSF13B. Moreover, inflammatory stromal cells can activate naive neutrophils to acquire an inflammatory phenotype as is seen in patients. Previously, we have shown that inflammatory stromal cells characterized the bone marrow of newly diagnosed myeloma patients. Here, we generate single cell RNA sequencing dataset of non-hematopoietic bone marrow cells of patients after induction treatment, high-dose melphalan, stem cell transplantation and consolidation treatment. We show that this intensive treatment reduced, but did not normalize, stromal inflammation.

RNA sequencing of the non-hematopoietic microenvironment of aspirates from Multiple Myeloma patients at diagnosis and after treatment versus non-cancer controls

Project description:By generating a paired single cell RNA-sequencing database of the tumor niche from 10 newly diagnosed MM patients, we created a unique dataset allowing the in-depth analyses of stromal-immune interactions within the tumor microenvironment (see related accession number).

By tracking inflammatory signatures over time in individual patients undergoing first-line treatment using bulk RNA sequencing, we show that bone marrow inflammation is not reverted by successful anti-tumor therapy (this dataset), suggesting a role for stromal fibroblasts and bone marrow inflammation in disease persistence or relapse. Raw sequencing data files will be deposited to EGA.

Single-cell transcriptomic analysis of NK cell dynamics in myeloma patients reveal persistent reduction of cytotoxic NK cells from diagnosis to relapse

Project description:Single-cell transcriptomics was performed to investigate the bone marrow NK cell compartment of myeloma patients at diagnosis (n=19), during treatment (n=21) and at relapse (n=6). The bone marrow of myeloma patients is characterized by a reduction in conventional cytotoxic NK cells that persists throughout treatment. We show in 20% of newly diagnosed myeloma patients that an altered balance between cytotoxic and cytokine-producing NK cells translates into a reduced cytotoxic ability in response to therapeutic antibodies. The relative loss of cytotoxic NK cells persists at relapse and is accompanied by an expansion of IFN-responsive NK cells. These findings reveal previously unappreciated alterations in bone marrow NK cell composition and highlight the importance of understanding the bone marrow immune system in patients receiving immunotherapies.

RNA-Seq analysis of LYN deficient HS-5 stroma cells cocultured with primary human CLL cells

Project description:LYN kinase is a tyrosine kinase, that regulates cellular homeostasis in a context-specific manner. Our group could show, that its expression in the leukemic microenvironment of chronic lymphocytic leukemia contributes to disease progression (Nguyen PH et al.; Cancer Cell; 2016). To analyze the effect of LYN kinase on the leukemia supportive phenotype of the bone marrow stromal cell line HS-5, we generated single cell clones of LYN deficient stroma cells. These cells were analyzed in a Multi-Omic approach, including ARNA-Seq of stromal cells after 72h of coculture with primary human chronic lymphocytic leukaemia (CLL) samples.

Single-cell RNAseq of human bone marrow cells (Drop-seq)

Project description:Gene expression profiles of individual bone marrow cells were acquired by Drop-Seq. Total bone marrow (TBM) and weakly lineage depleted bone marrow (DBM; CD235a and/or Cd45 negative) and stromal cells (STRO-1 positive or collagenase IV released) were analysed.

Bulk RNAseq of control and 5TGM1 myeloma-bearing bone marrow T, NK, and non-hematopoietic stromal cells from C57Bl/6 mice

Project description:We hypothesized that the immune microenvironment of the bone marrow influences the progression of myeloma outgrowth in the 5TGM1 transfer model of multiple myeloma. Therefore we sorted bone marrow T, NK, and non-hematopoietic stromal cells from control and tumor-bearing C57Bl/6 mice.

Single cell RNA-sequencing of murine endothelial and stromal populations at embryonic day 17 (E17)

Project description:The origin of bone marrow stromal cells (BMSCs) is not completely understood. We have identified a rare population of cells with a transcriptional profile consistent with endothelial to mesenchymal transition (Endo-MT) in human fetal development. Therefore, we hypothesized that Endo-MT contributes to bone marrow niche formation in mammals. Here, we sought to determine whether Endo-MT cells could be identified in murine bone marrow during embryonic development. We isolated bone marrow and collagenased bone fraction from long bones of 9 fetuses at embryonic day 17 (E17) and FACS purified endothelial cells and BMSCs for single cell RNA sequencing.

Bulk RNA sequencing of endothelial-derived and non-endothelial-derived BMSCs and OLCs of VE-Cadherin-Cre;LoxP-tdTomato mice

Project description:We performed lineage tracing experiments using VE-Cadherin-Cre;LoxP-tdTomato mice. In these mice, endothelial cells (ECs) and their progeny are permanently marked by tdTomato fluorescence. We found that a substantial subset of stromal cells is derived from ECs, as indicated by their tdTomato expression. These findings support the notion that endothelial to mesenchymal transition (EndoMT) contributes to hematopoietic bone marrow niche formation in mice. Here we sought to determine the transcriptomic differences between endothelial-derived (tdTomato-positive) and non-endothelial-derived (tdTomato-negative) bone marrow stromal cells (BMSCs) and osteo/chondrolineage progenitor cells (OLCs). Murine niche populations were obtained from collagenased bone fraction of VE-Cadherin-Cre;LoxP-tdTomato mice at 3 weeks (n=2) or 11 weeks (n=2) of age. BMSCs (CD45-TER119-CD31-CD144-SCA-1+ CD51+ cells) and OLCs (CD45-TER119-CD31-CD144-Sca1-CD51+ cells) were FACS-purified and sequenced.
