Project description:This SuperSeries is composed of the following subset Series: GSE37028: Microarray analysis of Zbtb46 KO CD4+ Splenic DCs and bone marrow erythroid progenitors GSE37029: Microarray analysis of WT bone marrow myeloid progenitors, BM cultured with GM-CSF and M-CSF, and monocytes treated with GM-CSF Refer to individual Series
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.
Project description:Administration of G-CSF mobilizes a unique population of CD11b+Ly6C+CD34+mature monocytes that can inhibit GVHD in murine models of BMT via an iNOS-dependent mechanism. The transcriptional profiles of flow sorted lineage-CD11b+CD34+ cells from G-CSF treated mice were compared with conventional splenic Ly6C+ and Ly6C- monocytes, progenitor cells and cultured myeloid-derived suppressor cells. Further comparisons were made with lineage-CD11b+CD34+ cells from G-CSF treated mice that had been grown in culture or that were derived from iNOS ko mice. We used microarrays to detail the global programme of gene expression underlying diffrenetiation of each of these cell types Lin-CD11b+CD34+ populations were isolated directly from the spleens of G-CSF-treated C57BL/6 mice or iNOS ko mice. In untreated C57BL/6 mice, Lin-CD11b+CD115+Ly6C+ and Lin-CD11b+CD115+Ly6C- monocytes were isolated from the spleen and Lin-CD117+CD115+CD135-Ly6C+CD11b- common monocyte progenitors were isolated from the bone marrow. Myeloid-derived suppressor cells (Ly6C+CD11b+ cells derived from G-CSF, GM-CSF and IL-13 cultured C57BL/6 bone marrow) were also isolated and compared with the above populations. Lin-CD11b+CD34+ spleen cells derived from G-CSF-treated C57BL/6 mice were cultured for 3 days in Flt3 ligand and SCF and then compared to the original input population.
Project description:CD11bloLy6CloLy6Glo cells were sorted from the steady-state bone marrow (BM) of B6 mice, i.e. cells cultured for 5 d without human BM-derived mesenchymal stromal cells (MSCs) in the absence of GM-CSF. CD11bhiLy6ChiLy6Glo cells were isolated from BM cells cultured for 5 d under GM-CSF incubation (40 ng/ml) but without MSC coculture. CD11bmidLy6CmidLy6Glo cells were sorted from GM-CSF-stimulated, MSC-cocultured BM cells.
Project description:Bone marrow cells were isolated, primed with M-CSF (M-BMDM) or GM-CSF (GM-BMDM) and cultured for 7 days. The proteomic difference between GM-BMDM and M-BMDM were analyzed to describe the phenotye and function of two types of macrophages.
Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM).

Bone marrow cells were differentiated for 7 days with 25 ng/ml GM-CSF or 20% L cell conditioned media as a M-CSF supplier. GM-BMDCs were sorted from MHCIIhighF4/80low population and GM-BMMs were sorted in the MHCIIlowF4/80high population. M-BMMs were sorted from CD11b+F4/80+ population.
Project description:Bone marrow cells (BM) were isolated and primed with M-CSF (M BMDM) or GM-CSF (GM BMDM) for 7 days. M-BMDMs were treated with IL6 (20 ng/ml) for 3 h or 24 h while GM-BMDMs were treated for 3 h. The difference between BM, M-BMDM, and GM-BMDM were analyzed to describe the phenotye and function of each population. Moreover, by RNA-seq analysis, the influence of IL6 treatment on GM-BMDMs and M-BMDMs were analyzed.
Project description:Bone marrow-derived MDSCs were generated from bone marrow of naive WT or Rel-/- mice. After red blood cell lysis, BM cells were cultured in complete RPMI medium containing GM-CSF (100 ng/mL) and IL-6 (100 ng/mL) for 7 days. RNAs were collected afterwards for RNA-Seq.
