(Submitter supplied) Epigenetic mechanisms regulate the multilineage differentiation capacity of hematopoietic stem cells (HSCs) into a variety of blood and immune cells. Our recent work revealed evidence of multilineage gene priming in HSCs, where open cis-regulatory elements (CREs) exclusively shared between HSCs and unipotent lineage cells were enriched for DNA binding motifs of known lineage-specific transcription factors. more...

(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) Integration of index sorting and single cell functional assays allowed identification of novel haematopoietic stem cell (HSC) and multiprogenitor subsets (MPP) that differ in their lineage differentiation potential in vitro and in vivo, cell cycle properties and long-term repopulation capacity in the NSG xenograft model. Here we report single cell transcriptomes of CD49f+ HSCs as well as those of CD49f+ Subset1 (CD19- CD38- CD45RA- CD90+ CD49f+ CD34lo CLEC9Ahi, Myelo-erythroid-skewed in vitro but Lymphoid-competent) and CD49f+ Subset2 cells (CD19- CD38- CD45RA- CD90+ CD49f+ CD34hi CLEC9Alo, Myelo-Lymphoid competent but Erythroid-deficient). more...

(Submitter supplied) Epigenetic modifications must underlie lineage-specific differentiation since terminally differentiated cells express tissue-specific genes, but their DNA sequence is unchanged. Hematopoiesis provides a well-defined model of progressive differentiation in which to study the role of epigenetic modifications in cell fate decisions. Multi-potent progenitors (MPPs) can differentiate into all blood cell lineages, while downstream progenitors commit to either myeloerythroid or lymphoid lineages. 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...

Haematopoietic progenitors in the embryo manifest restricted differentiation potential relative to definitive haematopoietic stem cells in adult bone marrow, which support lifelong multilineage haematopoiesis.
