The long-term maintenance of hematopoietic stem cells (HSCs) relies on the regulation of endoplasmic reticulum (ER) stress at a low level, but the underlying mechanism remains poorly understood. Here, we demonstrate that suppression of ER stress improves the functions of HSCs and protects HSCs again...

Mitochondrial fatty acid oxidation (FAO) is essential for hematopoietic stem cell (HSC) self-renewal; however, the mechanism by which mitochondrial metabolism controls HSC fate remains unknown. Here, we show that within the hematopoietic lineage, HSCs have the largest mitochondrial NADPH pools, w...
We used comparative transcriptome analysis to determine the relationship between rodent Multipotent Adult Progenitor Cells (MAPCs) and pluripotent embryonic stem cells (ESCs), or lineage restricted mesenchymal stem cells (MSCs) and neurospheres (NS). This comparison revealed a unique gene expression...
Hematopoietic stem cells (HSC) possess life-long self-renewal activity and generate a series of multipotent progenitors that differentiate into lineage-committed progenitors and subsequently mature cells. Recently, functionally distinct stem and progenitor cell types have been identified, however, a...
Here we describe that lysine-specific demethylase 1 (Lsd1/KDM1a), which demethylates histone H3 on LysM-bM-^@M-^I4 or LysM-bM-^@M-^I9 (H3K4/K9), is an indispensible epigenetic governor of hematopoietic differentiation. Integrative genomic analysis in primary hematopoietic cells, combining global occ...
Polycythemia vera (PV) is a myeloproliferative neoplasm (MPN) characterized by hyper-proliferation of the erythroid, megakaryocytic and granulocytic lineages and the presence of an activating mutation in JAK2. To elucidate mechanisms that regulate PV stem cells, we applied a newly developed data-ind...
The transcription factor RUNX1 is frequently mutated in myelodysplastic syndrome and leukemia. RUNX1 mutations can be early events, creating pre-leukemic stem cells that expand in the bone marrow. Here we show that, counter-intuitively, Runx1 deficient hematopoietic stem and progenitor cells (HSPCs)...
