(Submitter supplied) Declining immune function with age is associated with reduced lymphoid output of hematopoietic stem cells (HSCs). Currently, there is poor understanding of the dynamic changes with age in the heterogeneous multipotent hematopoietic progenitor cell compartment, which regulates output of differentiated lymphoid cells. In this study, we observed progressive and specific loss of lymphoid-primed multipotent progenitor cells (LMPP/MPP4) as young animals began to age. more...

(Submitter supplied) Here, we use single-cell RNA-Seq to examine variation between individual hematopoietic stem and progenitor cells from two mouse strains (C57BL/6 and DBA/2) as they age. We prepared libraries from long-term (LT-HSCs) (LSK CD150+CD48-), short-term hematopoietic stem cells (ST-HSCs) (LSK CD150-CD48-) and multipotent progenitors (MPPs) (LSK CD150+CD48+) from young (2-3 months) and old mice (22 months for C57BL/6 and 20 months for DBA/2). more...

(Submitter supplied) Hematopoietic stem cells (HSCs) must balance self-renewal and lineage differentiation to regenerate the hematopoietic system throughout life. HSCs exhibit lineage-associated gene expression that keeps them responsive to demands of mature blood production. However, it is not known whether this process, termed lineage priming, directly influences HSC self-renewal. We investigated the link between stemness and lineage priming by attenuating the early lymphoid transcription factor E47 through ID2 over-expression (OE). more...

(Submitter supplied) 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). more...

(Submitter supplied) 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. more...

(Submitter supplied) Hematopoietic stem cells and multipotent progenitors (MPPs) commitment can be tuned in response to an infection so that their differentiation is biased toward myeloid cells. Here we find that Bach2, which inhibits myeloid differentiation in common lymphoid progenitors, represses a cohort of myeloid genes and activates those linked to lymphoid function. Bach2 repressed both Cebpb and its target Csf1r, encoding C/EBPβ and macrophage colony-stimulating factor receptor (M-CSFr), respectively, whereas C/EBPβ repressed Bach2 and activated Csf1r. more...

(Submitter supplied) An optimized whole genome bisulfite sequencing protocol (µWGBS, Farlik et al. 2015 Cell Reports) was used to establish DNA methylation profiles of FACS-purified stem and progenitor cells types of the human blood lineage. Most cell types were sorted from the peripheral blood of three donors each (43 donors total) with eight pools of ten cells, two pools of 50 cells, and one pool of 1000 cells. Additionally, two cell types (HSC, MPP) were sorted from bone marrow, fetal liver, and cord blood; single-cell methylome sequencing (scWGBS, Farlik et al. more...

(Submitter supplied) Haematopoietic stem cells (HSC) and multipotent progenitor cells (MPP) generate all cells of the blood system, although cellular heterogeneity and bias in lineage potential have been observed. Here, we examined whether lineage-specific transcription factors, such as the B-lineage determinant EBF1, establish lineage bias in early progenitors. We detect low level EBF1 expression in myeloid-biased MPP3 and lymphoid-biased MPP4 cells, and show that Ebf1-deficient animals display reduced HSC quiescence and repopulation capacity, enhanced myelopoiesis and enhanced myeloid differentiation potential of MPP3 and MPP4 cells. more...
