Full-length, single cell RNA-sequencing of human bone marrow subpopulations reveals hidden complexity

ABSTRACT: Here, we investigate the extent to which individual cells within the total bone marrow (tot-BM) and the lineage negative (Lin-neg) populations exhibit this isoform diversity and whether distinct subpopulations in tot-BM and Lin-neg cells intersect based on transcript isoform usage. We extracted healthy donor human bone marrow tissues from discarded harvesting filters. From this total bone marrow cell preparation (tot-BM) we enriched for lineage-negative progenitor cells (Lin-neg) by magnetic selection as described earlier (Deslattes Mays et al. 2019). We then analyzed total and Lin-neg cell populations by droplet-based single cell RNA sequencing (10xGenomics). In order to increase the number of mRNA molecules detectable per cell we reduced the cell input to approximately 500 cells for each experiment. After single-cell selection, the barcoded cDNA libraries were equally divided and each pool was analyzed in parallel by short-read sequencing (Illumina) and by single-molecule real-time (SMRT) full-length RNA sequencing (Pacific Biosciences).

The effect of periodontitis - induced trained immunity on the epigenomic profile of mouse bone marrow LSK and GMP cells

Project description:Peripheral inflammation affects hematopoietic stem and progenitor cells (HSPCs) in the bone marrow and induce myeloid lineage skewing of the progenitor cells. In this study, we performed single cell ATAC-sequencing in LSK (Lin—Sca-1+cKit+ ) and GMP (Lin—c-Kit+Sca1—CD16/32+CD34+) cells to determine the impact of ligature-induced periodontitis (LIP) on the epigenomic profile of these BM cells.

Bone marrow-derived myofibroblasts contribute to the mesenchymal stem cell niche and promote tumor growth

Project description:Carcinoma-associated fibroblasts (CAFs) that express α-smooth-muscle-actin (αSMA+) contribute to cancer progression, but their precise origin and role in tumorigenesis is not established. Using mouse models of inflammation-induced gastric cancer, we show that at least 20% of CAFs originate from bone marrow and derive from mesenchymal stem cells (MSCs). Surprisingly, we find that αSMA+ myofibroblasts (MF) are niche cells normally present in bone marrow and increase markedly in the bone marrow and blood during progression to dysplasia. MSC-derived CAFs that are recruited to the dysplastic stomach express IL-6, Wnt5α and BMP4 and show DNA hypomethylation. Bone marrow (BM)-derived CAFs strongly promote tumor growth in organotypic and xenograft models. In addition, CAFs are generated from MSCs and are recruited to distant tumor sites in a TGF-β- and SDF-1α-dependent manner. Carcinogenesis therefore involves the expansion and relocation of normal bone marrow niche cells to the tumor site where they create a new niche to sustain cancer progression. Since resident (non-BM-derived) CAFs could not be cultured and directly compared to BM-derived CAFs, we additionally isolated total RFP(+) gastric CAFs from aSMA-RFP mice with Helicobacter felis-induced dysplasia, and compared them to GFP(+) BM-derived gastric CAFs from mice with H. felis-induced dysplasia mice that had been transplanted with UBC-EGFP bone marrow. The RFP+ CAFs (HF CAF) represent total CAFs (of which only 20% were BM-derived), while the latter represented only BM-derived CAFs (BM CAF). We compared their gene expression using the Illumina array (MouseWG-6v2) directly after FACS sorting. Interestingly, the GFP+ BM-derived CAFs expressed higher levels of inflammatory genes (IL-6, IL-1β, IL-33) and a number of tumor and stem cell associated factors (CCL5, SPP1, Notch3, MMP9, CD47, CXCR4, PARP10,) compared to the total (RFP+) population of gastric CAFs.
