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

ABSTRACT: 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.

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

Project description: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.

Single-cell RNA sequencing of RUNX1-RUNX1T1(9a) transformed mouse bone marrow cells

Project description:Single-cell RNA sequencing analysis of RUNX1-RUNX1T1(9a) transformed c-kit positive cells with (Kat2a WT) and without Kat2a (Kat2a NULL). Lineage negative bone marrow cells were collected from Kat2a fl/fl Mx1-Cre-/- and Kat2a fl/fl Mx1-Cre +/- animals after pIpC treatment and transduced with RUNX1-RUNX1T1(9a) expressing retrovirus (reported by GFP expression). Cells were injected into irradiated C57BL6 mice and GFP positive c-Kit positive bone marrow cells collected 2 and 4 months after transplantation. Cells were processed for single-cell RNA sequencing library preparation (10X chromium single cell) and next gene sequencing following 10X genomics v2 protocol.

IL-4 stimulation of Dicer deficient bone-marrow derived macrophages in vitro

Project description:Macrophages were derived from the bone-marrow of 3 x fl/+ Dicer LysCre +/- (wild-type) and 3 x fl/fl Dicer LysCre +/- mice and stimulated with IL-4 (50ng/mL) for 72h. Total RNA was isolated and analyzed by gene array. In this experiment, we derived Dicer deficient bone-marrow macrophages using Dicer fl/+ LysM-Cre by Dicer fl/+ crossed mice to obtain Dicer fl/fl LysM-cre progeny (and Dicer deficient macrophages). Next, we studied the effects of IL-4 stimulation in macrophage with a deficiency in Dicer/microRNAs.

Chronic active pre-B cell receptor signaling drives BCL6 expression and represents a therapeutic target in a distinct subtype of acute lymphoblastic leukemia

Project description:BCL6fl/fl mouse bone marrow pre-B cells were transduced with an TCF3-PBX1 vector. The TCF3-PBX1 transduced BCL6fl/fl pre-B cells were then transduced with an empty vector (EV), or a Cre vector for Cre-mediated BCL6 deletion. Effect of BCL6 deletion in the TCF3-PBX1 pre-B cells were studied by Affymetrix GeneChip Mouse Genome 430 2.0 Arrays. TCF3-PBX1 transduced BCL6fl/fl mice bone marrow pre-B cells were tranduced with an empty vector (EV) or a Cre vector for BCL6 deletion
