(Submitter supplied) To characterize early human hematopoiesis on a single-cell level we developed an approach termed index-omics, which combines flow-cytometric, single-cell transcriptomic and single-cell lineage fate data. Healthy human bone marrow was labeled with a panel of up to 11 FACS surface markers commonly used to identify human hematopoietic stem and progenitor cells (HSPCs). Lin-CD34+38+ progenitors and Lin-CD34+CD38- stem cell enriched HSPCs were individually sorted, their surface marker fluorescence intensities recorded, and subjected to single-cell RNAseq or single-cell ex vivo cultures.

(Submitter supplied) The classical tenet of hematopoiesis posits well-accepted lineage trees that arise from progressively restricted oligopotent and unipotent progenitor populations. However, because fate in hematopoiesis has mostly been studied in the context of transplantation, it is unclear whether these lineage branches and such proposed oligopotent progenitors exist in an unperturbed hematopoietic system. Here, we utilize endogenous transposon tagging to trace the fate of thousands of progenitors and stem cells over time to re-evaluate these dogmas. more...

(Submitter supplied) Fractionation of EML cells isolated based on surface expression of immunophenotypic markers reveals the existence of a subpopulation that has undergone spontaneous commitment to an erythroid fate. Uncommitted fractions were compared to committed cells, derived from both spontaneous (EryCP) and cytokine-driven (Ediff) commitment.

(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) Differentiation of adult hematopoietic stem cells (HSC) constantly produces the cell types of the blood and immune system. The dynamics of this process and the hierarchy of downstream oligopotent stem cell differentiation remain controversial. Here we dissect hematopoietic progenitor populations in a minimally biased fashion using extensive single cell sampling from murine bone marrow. We characterize the HSC population, define its quiescent transcriptional program and validate it with label retaining assays and cytokine mediated stimulations. more...

(Submitter supplied) Blood develops in distinct stages. Haematopoietic progenitors in the embryo manifest restricted differentiation potential relative to definitive haematopoietic stem cells in adult bone marrow, which support lifelong multilineage haematopoiesis. To identify regulators of embryonic haematopoiesis, we screened chromatin modifiers and identified the Polycomb group protein EZH1 as a barrier to multilineage potential from pluripotent stem cells (PSCs). 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) 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...
