In vivo modulation of the prostaglandin, interferon, or granulocyte colony-stimulating factor pathway induces rapid and specific transcriptional changes in hematopoietic stem cells with significant heterogeneity in the cellular response.

The H3K4 methyltransferase Setd1b is intrinsically required for hematopoietic stem and progenitor cell homeostasis and regulates lineage specification in mice.

Pre-hematopoietic stem cells emerge from the aortic floor according to two radically different morphodynamics whose biomechanics rely on controlling apicobasal polarity in hemogenic precursors, which may impact on their fate.

Application of a polyvinyl alcohol-based culture system reveals extensive differentiation but simultaneous robust murine hematopoietic stem cell (HSC) expansion, which are characterized by phenotypic, functional, and molecular properties shared with freshly isolated bone marrow HSCs.

Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.

Lysine-specific demethylase 1 (Lsd1) has an essential role during both the early and later stages of blood cell development.

Identification of distinct yolk sac-derived macrophage subpopulations in the fetal liver reveals their crucial role in shaping the hematopoietic niche, impacting erythropoiesis and granulopoiesis through direct interactions with long-term hematopoietic stem cells.

Isotope tracing, mathematical modeling, and single-cell ATP analysis reveal changes in blood cell metabolism under various conditions, showing stressed hematopoietic stem cells support hematopoiesis through glycolytic ATP production via PFKFB3.

Probing of various culture conditions leads to fundamental advances in ex vivo production of plasmacytoid dendritic cells for use in immunotherapy.

Mass spectrometry exposes a post-transcriptionally regulated reduction in protein diversity in hematopoietic stem cells, including a lack of detectable Dnmt3a protein levels despite mRNA levels comparable to progenitors.
