Functionally distinct subsets of lineage-biased multipotent progenitors control blood production in normal and regenerative conditions

Project description:To identify the molecular characterisitics of parallel lineage-biased MPP populations arising from hematopoietic stem cells (HSC) we conducted genome-wide analyses of hematopoietic stem, progenitor and mature myeloid cell populations using Affymetrix Gene ST1.0 arrays. Microarray analysis of 3-5 biological replicates of the indicated hematopoietic populations, isolated by FACS sorting from C57BL/6 mouse BM. Immunophenotypic definitions: Long-term HSC (HSCLT) (Lin-/cKit+/Sca1+/Flk2-/CD48-/CD150+); Short-term HSC (HSCST) (Lin-/cKit+/Sca1+/Flk2-/CD48-/CD150-); MPP2 (Lin-/cKit+/Sca1+/Flk2-/CD48+/CD150+); MPP3 (Lin-/cKit+/Sca1+/Flk2-/CD48+/CD150-); MPP4 (Lin-/cKit+/Sca1+/Flk2+); CMP (Lin-/cKit+/Fc?R-/CD34+); GMP (Lin-/cKit+/Fc?R+/CD34+); Pre-granulocyte (PreGr) (Mac1+/Gr1int); Granulocyte (Gr) (Mac1+/Gr1hi). HSC and GMP samples listed here were also used as controls for our related microarray study GSE48893.

Gene expression changes during hematopoietic cell differentiation

Project description:Gene expression analyses of hematopoietic stem cells (HSCs), progenitor cells (HPCs), and differentiated cell. Gene expressions of long-term HSCs (CD34-ckit+Sca1+Lineage-), short term HSCs (CD34+ckit+Sca1+Lineage-), Progenitor cells (ckit+Sca1- Lineage-), and differentiated cels (Lineage+) were examined by microarray. Results provide insight into the mechanism of hematopoietic cell differentiation. Long-term HSCs (CD34-ckit+Sca1+Lineage-), Short term-HSCs (CD34+ckit+Sca1+Lineage-), Progenitor cells (ckit+Sca1- Lineage-, and Lineage+), and differentiated cell (Lineage+) were sorted from mouse bone marraw and were examined by microarray. Results provide insight into the mechanism of hematopoietic cell differentiation.

miniChIP-chip of murine hematopoietic stem cells and progeny with H3K4me3, H3K79me2, H3K9/14ac, H3K27me3, H3K9me3, PolII

Project description:This study describes the changes in epigenetic chromatin modifications during murine hematopoietic stem cell differentiation in vivo using a modified miniChIP-chip technology. We have addressed issues including bivalent (H3K4me3/H3K27me3) modifications, lineage priming hypothesis, and stem cell chromatin properties in our study described in Weishaupt et al., 2009 (Blood) Comparison of 4 murine hematopoietic stem, progenitor and mature cell types directly isolated from primary tissues using FACS. HSCs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1+, CD150+, Flk2/Flt3- (LSKCD150+ cells). MPPs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1+, CD150-, Flk2/Flt3+ (LSKCD150- cells). PreMegEs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1-, CD150+, CD105-, FcgRI/IIlo and CD41- cells as described in Pronk et al., 2007. Splenic-derived CD4+ T cells are phentypically identified as CD4+, CD8-, B220-, Nk1.1- cells as described in Rolf et al., 2008.

Analysis of murine hematopoieitic stem cells, multipotent progenitors, PreMegE progenitors and mature CD4+ T cells

Project description:An investigation of the global gene expression signatures of murine hematopoietic stem cell differentiation during steady state hematopoiesis. This data compliments the miniChIP-chip data obtained from the same cell types as described in Weishaupt et al., 2009 (Blood). An Affymetrix genechip study using total RNA recovered from three separate FACS isolated HSC and MPP samples. The HSC and MPP gene expression data was analyzed alongside the PreMegEs and CD4+ T cells datasets obtained from our previous work (Pronk et al., 2007, Rolf et al. 2008). HSCs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1+, CD150+, Flk2/Flt3- (LSKCD150+ cells). MPPs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1+, CD150-, Flk2/Flt3+ (LSKCD150- cells). PreMegEs are phenotypically identified in bone marrow as lineage-, cKit+, Sca1-, CD150+, CD105- and CD41- as described in Pronk et al., 2007. Splenic-derived CD4+ T cells are phentypically identified as CD4+, CD8-, B220-, Nk1.1- cells as described in Rolf et al., 2008.

RNA-seq profiling of HSC, MPPs and HPC-1s from Phf6-deleted and Phf6-intact mice

Project description:The study profiled the effect of Phf6 deletion on gene expression in hematopoietic stem cells (HSCs), multipotent progenitor cells (MPPs) and hematopoietic progenitor cells (HPC-1). Phf6lox/Y;Tie2-creTg/+ mice were prepared on a C57BL/6 background so that Phf6 deletion could be selectively mediated by Tie2-cre. Cell populations were sorted from bone marrow samples using standard surface markers (Lin–SCA1+cKIT+(LSK) CD150+ CD48– for HSCs, Lin–SCA1+cKIT+(LSK) CD150– CD48– for MPPs and Lin–SCA1+cKIT+(LSK) CD150- CD48+ for HPC-1 cells). Phf6 intact and Phf6-delected cells of all three types were profiled by paired-end RNA-seq using an Illumina NextSeq 500 sequencer. RNA-seq libraries were prepared from the HPC-1 samples used a standard Illumina TruSeq library protocol whereas the libraries for the HSC and MPP samples used a SMART-seq ultra low input kit for cDNA synthesis and amplification. Statistical analysis of the TruSeq and SMART-seq samples was undertaken separately.

Expression data from LSK WT, GMP WT and GMP NcstnKO

Project description:Notch signaling is one of the central regulators of differentiation in a variety of organisms and tissue types. Within the hematopoietic system, Notch is essential for the emergence of definitive HSC during fetal life and controls adult HSC differentiation to the T-cell lineage. Notch activation is controlled by the gamma-secretase complex complex, composed of presenilin, nicastrin (Ncstn), anterior pharynx-1 (Aph1), and presenilin enhancer-2 To determine other role of Notch signaling in HSC we designed a conditional mouse model of Nicastrin deletion. WT and KO HSC were analysed to determined genes controlled by Notch signaling. Bone marrow lineage negative, cKit+, Sca1+ and lineage negative, cKit+, Sca1- CD34+ FcgammaRII/III+ cells were sorted from WT and Ncstn KO littermates for RNA extraction and hybridization on Affymetrix microarrays

Data set from hematopoietic stem cell transcriptome elucidating specific targets of Class 1A PI3K

Project description:Purpose: To detect the global effects of Class1A PI3K TKO deletion on the HSC transcriptome. Method: Whole BM cells from donor mice TKO: Pik3calox-lox; Pik3cblox-lox; Pik3cd-/-;Mx1-Cre, δ KO: Pik3calox-lox; Pik3cblox-lox;Pik3cd-/- (littermate control) and WT: WT, Mx1-Cre (control) were transplanted into lethally irradiated 6-8 week old B6.SJL mice (N=7 per group). Recipient mice were injected 4 weeks post transplant interperitoneally with pIpC 250μg x2, 48 hours apart to ensure Pik3ca and Pik3cb excision. At 4 weeks post PIPC, BM cells were harvested from femurs, tibiae, ilia and vertebrae by gentle crushing. Donor-derived HSCs (Lin-cKit+Sca1+Flk2-CD48-CD150+) cell populations were sorted into RNA extraction buffer (ARCTURUS PicoPure). cDNA was amplified from total RNA using the Ovation® RNA‑Seq System V2. Sequencing was performed using the NGS platform llumina-HiSeq2500/4000.

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.
