Project description:Recent studies have documented genome-wide binding patterns of transcriptional regulators and their associated epigenetic marks in hematopoietic cell lineages. In order to determine how epigenetic marks are established and maintained during developmental progression, we have generated long-term cultures of hematopoietic progenitors by enforcing the expression of the E-protein antagonist Id2. Hematopoietic progenitors that express Id2 are multipotent and readily differentiate upon withdrawal of Id2 expression into committed B lineage cells, thus indicating a causative role for E2A in promoting the B cell fate. Genome-wide analyses revealed that a substantial fraction of lymphoid and myeloid enhancers are pre-marked by H3K4me1 in multipotent progenitors. However, H3K4me1 levels at a subset of enhancers are elevated during developmental progression, resulting in evolving enhancer repertoires that we propose orchestrate the myeloid and B cell fates.

ChIP-Seq and gene expression profiling were performed in an inducible hematopoietic pluripotent cell line that can be differentiated into multiple lymphoid lineages. This submission contains gene expression profiling data. To characterize Id2-HPCs, we performed microarray analysis using RNA derived from cultured E2A-deficient cells, EBF-deficient cells and Id2-HPCs. Id2-HPC cells were cultured in IMDM medium supplemented with 10% FCS/2% PSG/β-me and IL7, Flt3-ligand, and SCF cytokines on S17 feeder cells in a humidified incubator at 37 degrees C with 5% CO2. Id2-HPC expanded cells were depleted of small (<1-5%) numbers of CD19-, CD25- and CD11b-positive cells by auto-MACS. E2A -/- and EBF -/- cells were cultured in IMDM supplemented with 10% FCS/2% PSG/β-me on S17 feeder cells in the presence of IL-7, Flt3-ligand, and SCF cytokines in a humidified incubator at 37 degree C with 5% CO2.

ChIP-Seq and gene expression profiling were performed in an inducible hematopoietic pluripotent cell line that can be differentiated into multiple lymphoid lineages. This submission contains gene expression profiling data. To compare the expression signatures from differentiated B- and myeloid-cells derived from hematopoietic progenitors that express Id2, Id2-HPCs were differentiated into either CD19+ B cells or CD11b+ myeloid cells. The gene expression profiles of differentiating B cells at 6-, 12-, 24-, 48-, 72-, 120-, and 240-hour time points were also investigated. RNA was isolated from the cultures and analyzed by microarray gene expression analysis. Id2-HPCs were cultured in IMDM medium supplemented with 10% FCS/2% PSG/β-me and IL7, Flt3-ligand, and SCF cytokines on S17 feeder cells in a humidified incubator at 37 degrees C with 5% CO2. Id2-HPC expanded cells were depleted of small (<1-5%) numbers of CD19-, CD25- and CD11b-positive cells by auto-MACS. For myeloid differentiation, cells were cultured for up to 6 days in IMDM medium supplemented with 10% FCS/2% PSG/β-me and IL3, Flt3L, GMCSF and MCSF cytokines. To promote B-cell differentiation, cells were cultured for up to 10 days in IMDM medium supplemented with 10% FCS/2% PSG/β-me and IL-7 and SCF cytokines on S17 feeder cells in the presence of 1 ug/mL doxycycline.

ChIP-Seq and gene expression profiling were performed in an inducible hematopoietic pluripotent cell line that can be differentiated into multiple lymphoid lineages. This submission contains ChIP-Seq data. Recent studies have demonstrated a tight correlation between transcriptionally active promoters and H3K4 trimethylation, whereas H3K4 monomethylation has been associated with enhancer activity. To determine whether the changes in gene expression patterns upon differentiation correlate with the presence of H3K4me3 as well as H3K4me1, ChIP-sequencing was performed on these two marks on cell lysates that were derived from Id2-HPCs and differentiated Id2-HPCs. The H3K4me1 marks were further analyzed to investigate the dynamics of enhancer repertoires between these cells. Id2-HPCs were cultured in IMDM medium supplemented with 10% FCS/2% PSG/M-NM-2-me and IL7, Flt3-ligand, and SCF cytokines on S17 feeder cells in a humidified incubator at 37 degrees C with 5% CO2. Id2-HPC expanded cells were depleted of small (<1-5%) numbers of CD19-, CD25- and CD11b-positive cells by auto-MACS. For myeloid differentiation, cells were cultured for up to 6 days in IMDM medium supplemented with 10% FCS/2% PSG/M-NM-2-me and IL3, Flt3L, GMCSF and MCSF cytokines. To promote B-cell differentiation, cells were cultured for up to 5 days in IMDM medium supplemented with 10% FCS/2% PSG/M-NM-2-me and IL-7 and SCF cytokines on S17 feeder cells in the presence of 1 ug/mL doxycycline, or alternatively, in alpha-MEM medium in the presence of cytokines and on Tst-4 stromal cells.

Abstract:
Blood cells are derived from a common set of hematopoietic
stem cells, which differentiate into more specific progenitors
of the myeloid and lymphoid lineages, ultimately leading to
differentiated cells. This developmental process is controlled
by a complex regulatory network involving cytokines and their
receptors, transcription factors, and chromatin remodelers.
Using public data and data from our own molecular genetic
experiments (quantitative PCR, Western blot, EMSA) or
genome-wide assays (RNA-sequencing, ChIP-sequencing), we have
assembled a comprehensive regulatory network encompassing the
main transcription factors and signaling components involved in
myeloid and lymphoid development. Focusing on B-cell and
macrophage development, we defined a qualitative dynamical
model recapitulating cytokine-induced differentiation of common
progenitors, the effect of various reported gene knockdowns,
and the reprogramming of pre-B cells into macrophages induced
by the ectopic expression of specific transcription factors.
The resulting network model can be used as a template for the
integration of new hematopoietic differentiation and
transdifferentiation data to foster our understanding of
lymphoid/myeloid cell-fate decisions.

Project description:The commitment of hematopoietic stem cells and multipotent progenitors (MPPs) can be tuned to reprogram their differentiation capacity to be biased toward myeloid cells in response to an infection. Bach2, which inhibits myeloid differentiation in common lymphoid progenitors, repressed a cohort of genes of myeloid function (myeloid genes) and activated those for lymphoid function (lymphoid genes) in MPPs. In addition, Bach2 repressed both Cebpb and its target Csf1, encoding C/EBPβ and macrophage colony-stimulating factor (M-CSF), respectively, whereas C/EBPβ repressed Bach2 and activated the M-CSF receptor gene Csf1r. Bach2 and C/EBPβ bound to overlapping regulatory regions of their myeloid target genes, suggesting the presence of a gene regulatory network (GRN) with mutual repression and antagonistic, feed-forward regulation of myeloid genes. Lipopolysaccharide reduced the expression of Bach2, resulting in enhanced myeloid differentiation. Bach2 tunes the commitment of multipotent progenitors to myeloid and lymphoid lineages under both normal and infectious conditions.

Project description:While most blood lineages are assumed to mature through a single cellular and developmental route downstream of hematopoietic stem cells (HSCs), dendritic cells (DCs) can be derived from both myeloid and lymphoid progenitors in vivo. To determine how distinct progenitors can generate similar downstream lineages, we examined the transcriptional changes that accompany loss of in vivo myeloid potential as common myeloid progenitors (CMPs) differentiate into common dendritic cell progenitors (CDPs), and as lymphoid-primed multipotent progenitors (LMPPs) differentiate into all lymphoid progenitors (ALPs). Microarray studies revealed that Interferon regulatory factor 8 (IRF-8) expression increased during each of these transitions. Competitive reconstitutions using Irf8-/- bone marrow demonstrated cell-intrinsic defects in the formation of CDPs and all splenic dendritic cell subsets. Irf8-/- CMPs and, unexpectedly, Irf8-/- ALPs produced more neutrophils in vivo than their wild type counterparts at the expense of DCs. Retroviral expression of IRF-8 in multiple progenitors led to reduced neutrophil production and increased numbers of DCs, even in the granulocyte-macrophage progenitor (GMP), which does not normally possess conventional DC potential. These data suggest that IRF-8 represses a neutrophil module of development and promotes convergent DC development from multiple lymphoid and myeloid progenitors autonomously of cellular context. CMP (Lineage-c-kithiSca-1-CD11c- CD34+ Flk2+CD16/32-CD115- ) or CDP (Lin-c-kitintSca-1-CD34+Flk2+CD16/32-CD115+) were double sorted from the bone marrow of wild type C57BL/6 mice. RNA was extracted from 10,000-30,000 sorted cells using Trizol (Invitrogen) and linear acrylamide (Ambion), amplified using Affymetrix Two-Cycle Amplification and IVT kits (Affymetrix), and hybridized to Affymetrix Mouse Genome 430 2.0 chips.
