Transcription profiles of WT and CreER-Raptor-flox/flox common myeloid progenitors (CMP), granulocyte-macrophage progenitor (GMP), or lineage negative (Lin-) stimulated with M-CSF for 12 hours

ABSTRACT: Myelopoiesis is impaired in Raptor-deleted mice (CreER-Rptor-flox/flox). To evaluate the transcriptional changes in myeloid precursors , we isolated CMP (Lin–Sca-1–c-Kit+CD34+FcγRII/IIImid), GMP (Lin–Sca-1–c-Kit+CD34+FcγRII/IIIhigh) and Lin (B220, Ly6C, Ly6G, CD3, Ter-119) negative cells (Lin–) from bone marrow of WT or CreER-Rptor-flox/flox mice. RNA was isolated from CMP and GMP immediately after sorting and Lin- cells were cultured for 12 hours with M-CSF (10 ng/mL) in 10% FBS and 1% P/S DMEM before RNA isolation. We used microarrays to compare the global transcription profiles of CMP, GMP, or Lin– stimulated with M-CSF for 12 hours from WT and CreER-Raptor-flox/flox mice.

Transcription profiles of fate mapped IL17aiCre+flox/stop/flox-YFP+ TH17 cells, CD44intCD27+ TH17 cells and CD44hiCD27- TH17 cells from WT or Raptor-ko (flox/flox) mice after immunization with Myelin Oligodendrocyte Glycoprotein (MOG)

Project description:Mechanisms governing memory responses in IL-17 secreting CD4+ T cells (TH17), especially in autoimmune disorders, remain poorly understood. TH17 cells play pleiotropic roles in autoimmunity and tissue inflammation and are characterized by inherent plasticity, although how plasticity is regulated remains elusive. We investigated the transcriptional profiles of fate mapped (IL17aiCre-flox/stop/flox-YFP) TH17 cells and WT and Raptor-ko (flox/flox) TH17 cells (both IL17aiCre-flox/stop/flox-YFP) as well as sorted within CD27+ and CD27- subsets of WT in experimental autoimmune encephalomyelitis, a human model for human multiple sclerosis. We used microarrays to compare the global transcription profiles of YFP+ (IL17aiCre-flox/stop/flox-YFP) fate mapped TH17 cells as well as CD27+ and CD27- subsets of CD44+ fate mapped TH17 cells from draining lymph nodes on day 9 after immunization with Myelin oligodendrocyte glycoprotein from WT and IL17aCre-Raptor-flox/flox mice.

Tet2-/-Flt3ITD and WT stem and progenitor cells

Project description:The study was a comparison of gene expression using RNA-seq. We analyzed the stem and progenitor cells from WT and Vav-cre+ Tet2fl/fl Flt3-ITD (T2F3) mice. We isolated stem cells LSK (lin- sca+ kit+) and granulocyte-macrophage progenitors GMP (lin- sca- kit+ fcgr+ cd34+) cells from bone marrow. Comparisons were made across genotypes WT vs. T2F3 and cell types LSK vs. GMP.

Microarray analysis of WT bone marrow myeloid progenitors, BM cultured with GM-CSF and M-CSF, and monocytes treated with GM-CSF

Project description:Analysis of genes induced in DC precursors and in BM cells and monocytes treated with GM-CSF For progenitor arrays, bone marrow progenitors (CMP, GMP, CDP, and pre-cDC) were harvested from WT C57Bl/6 mice. For culture arrays, BM was cultured in the presence of GM-CSF or M-CSF and adherent and non-adherent cells sorted. For monocyte cultures, sorted BM monocytes were treated with GM-CSF for 0, 24 or 48 hours.

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.

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.

Gene-expression changes resulting from loss of the mTORC1 component Raptor in murine hematopoietic stem and progenitor cell-enriched populations (HSPC)

Project description:We investigated the role of mTORC1 in murine hematopoiesis by conditionally deleting the Raptor gene in murine hematopoietic stem cells. We observed mutliple alterations evoked by Raptor loss in hematopoiesis and profiled gene-expression alterations induced by raptor loss in Flt3-Lin-Sca1+cKit+ hematopoietic stem and progenitor enriched cell populations, 5 weeks post Raptor deletion. Flt3-Lin-Sca1+cKit+ cells were flow sorted from mice containing homozygous floxed alleles for exon 6 of the Raptor gene in the presence (MT group) or absence (WT group) of the MxCre transgene, which was induced with injections of mice with pIpC 5 weeks before cell isolation.
