Next Generation Sequencing Facilitates Quantitative Analysis of Wild Type and POT1a deleted MSPCs Transcriptomes.

ABSTRACT: Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to evaluate POT1a deleted MSPCs functions by using NGS-derived MSPCs transcriptome profiling (RNA-seq) in vitro and vivo. Methods: In vitro, bone marrow cells flushed out from mouse femurs and tibiae were cultured, and adherent cells were collected. CD51+/PDGFRɑ+ cells were sorted and further cultured, and Cre Recombinase Gesicles were applied. After 48 hours culture, tdTomato fluorescently colored cells were re-sorted, cultured for about 4 weeks, and used for gene analyses. In vivo, bone marrow cells weer flushed out from mouse femurs and tibiae, and the flow-through fraction with tdTomato signals was sorted as an MSPC-enriched population. Results: Gene set enrichment analysis of the differentially expressed genes revealed that several pathways related to bone development were significantly affected. Conclusions: POT1a is essential for bone marrow MSPCs to maintain osteo- differentiation potential.

Genome-wide maps of hematopoietic stem and progenitor cells in mice bone marrow.

Project description:Purpose: To investigate whether the skeletal retardation observed in NG2-cre/Pot1afl/fl mice affected hematopoiesis. Methods: Whole bone marrow cells mRNA profiles of 2-week-old wild-type (NG2-cre/Pot1awt/wt) and Pot1a knockout (NG2-cre/Pot1afl/fl) mice were generated by deep sequencing, using Illumina NextSeq 500. Results: We compared the relative sizes of these subpopulations between the NG2-cre/Pot1afl/fl and control mice and found a significant reduction in cells of the B-cell lineage in NG2-cre/Pot1afl/fl marrow. Cell subpopulations associated with B-cell differentiation from hematopoietic stem/progenitor cells (HSPCs) were identified according to the expression of established marker genes. Conclusions: Bone marrow microenvironments composed of POT1a-deleted MSPCs impair B-cell development.

RNA sequencing data of bone marrow endothelial cell subpopulations type H, type E and type L

Project description:This dataset was generated by RNA sequencing of bone marrow endothelial cells from femurs and tibiae of 6 day-old C57Bl/6 mice. Sample sets represent type H, type E and type L bone marrow endothelial cell subpopulations. Endothelial subpopulations are defined by their expression levels of Endomucin and CD31/Pecam1. Each dataset was generated in triplicates.

Human bone and marrow niche formation by mesenchymal progenitors in vivo is predefined by an organotypic epigenetic signature

Project description:In this study, we have analyzed DNA methylation characteristics of human mesenchymal stem and progenitor cells (MSPCs) form different tissue sources including bone marrow (BM), white adipose tissue (WAT ), umbilical cord (UC) as well as dermal fibroblasts by using the HumanMethylation450K array. Cells able to form bone through endochondral ossification and attract bone marrow in an innovative in vivo model were compared to cells lacking these capacities. Interestingly only BM-derived MSPCs were capable of bone formation and marrow attraction. These features correlated with unique epigenetic characteristics potentially enabling BM-derived cells to undergo endochondral ossification. 12 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip

RNASeq of bone lining niche cell components from healthy vs. myeloma-bearing mice

Project description:We compare gene expression in FACS-sorted bone-lining cell components: stromal progenitors, osteoprogenitors and endothelial cells, from myeloma-bearing vs. from healthy mice, and also between myeloma cells flushed from the central bone marrow vs. myeloma cells digested from the bone surface (myeloma-bearing mice only). The myeloma model used is the 5TGM1 murine myeloma cell line, injected into immunocompetent KaLwRij mice.

Gene expression profiling of osterix-derived cells from control and PTH1R knockout mice in osteoprogenitors

Project description:We used Osx-Cre:GFP / ROSA26-loxP-stop-loxP-tdTomato mice with or without PTH1Rfl/fl. Bone marrow and bone were digested to make single cell suspension, and sorted by fluorescence. Bulk cell RNA sequencing were performed to identify specific transcripts from osterix-derived cells.

Genome-wide sequencing of cultured MDSCs obtained from bone marrow of lnc57Rik ko , lncGM1082 ko and WT mice.

Project description:To fully elucidate the effects of long non-coding RNA 5730403I07Rik (lnc57Rik) and lncGM1082 on myeloid-derived suppressor cell (MDSCs), we generated lnc57Rik knockout (KO) and lncGM1082 ko mice. Then bone marrow cells were obtained from the femurs of C57BL/6, lnc57Rik KO, or lncGM1082 ko mice and cultured in RPMI-1640 medium supplemented with GM-CSF plus IL6 for 4 days. We further performed a high-throughput sequencing analysis in cultured MDSCs obtained from bone marrow of lnc57Rik ko, lncGM1082 ko and wild type (WT) mice.

Oligomeric human Aβ1-42 inhibits antigen presentation

Project description:The goal of this study is to investigate the involvement of inflammation in Alzheimer’s disease (AD) and to clarify the signaling pathways involved in the presence of beta-amyloidosis, a hallmark of AD pathogenesis, to help identifying potential targets for therapy. To do that, we isolated bone marrow-derived progenitor cells from femurs, tibiae and hip bones of non-transgenic C57BL/6 mice according to established protocols , and we maturated them with LPS. To obtain an unbiased view of gene regulation in mouse bone marrow-derived dendritic cells (BM-DCs) exposed to pre-aggregated beta-amyloid peptide (Aβ) oligomers, we analyzed the transcriptome of untreated immature control BM-DCs (‘Ctrl’), LPS-treated BM-DCs (’LPS’), Aβ1-42 oligomer-treated BM-DCs (‘Aβ‘) and BM-DCs treated with Aβ1-42 oligomers and LPS (‘Aβ+LPS‘) via explorative RNA-sequencing.

Bone marrow adipocyte (BMAd)-specific deletion of Pnpla2 reveals local roles for lipolysis to fuel cells of bone and the marrow niche

Project description:Purpose: To determine mechanisms by which BMAd-Pnpla2 deficiency-causes bone loss in calorie restricted (CR) mice, we profiled global gene expression in bone marrow plugs from distal tibiae, a location highly enriched with bone marrow adipose tissue. Methods: Male control and BMAd-Pnpla2-/- mice at 24 weeks of age were either fed AL or underwent 30% CR for 6 weeks. Distal tibial cBMAT was flushed and cBMAT from two mice was pooled as one sample for RNAseq analyses (n of 3 or 4 per treatment). Results: Using an optimized data analysis workflow, we mapped about 20 million sequence reads per sample to the mouse genome (UCSC mm10) and identified 23,441 transcripts in the bone marrow adipose tissue of WT and Pnpla2 deficiency mice using STAR with default parameters. PCA plots show that RNA profiles from CR groups are distinct from their Ad libitum (AL) controls. Whereas Pnpla2 deficiency in mice fed AL does not cause gene expression to diverge substantially, loss of Pnpla2 interacts with CR resulting in a well-segregated pattern of gene expression Conclusion: Caloric restriction induces dramatic elevations in extracellular matrix organization and skeletal development genes, and energy from BMAd is required for these adaptations.
