    The vascular niche controls Drosophila hematopoiesis via fibroblast growth factor signaling

    Manon Destalminil-Letourneau, Ismaël Morin-Poulard ... Michele Crozatier
    Two niches contribute to the control of Drosophila blood cell homeostasis through their differential regulation of hematopoietic progenitors.

    Osterix-Cre marks distinct subsets of CD45- and CD45+ stromal populations in extra-skeletal tumors with pro-tumorigenic characteristics

    Biancamaria Ricci, Eric Tycksen ... Roberta Faccio
    Osterix, a transcription factor regulating osteoblast differentiation and bone formation, is expressed in subsets of CAFs with osteogenic features and marks tumor infiltrating immune populations enriched in immune suppressive markers.

    lncRNA requirements for mouse acute myeloid leukemia and normal differentiation

    M Joaquina Delás, Leah R Sabin ... Gregory J Hannon
    A comprehensive analysis of long noncoding RNAs in the hematopoietic system reveals their dynamic regulation and a loss-of-function screen identifies some required for leukemia progression and involved in normal myeloid differentiation.

    Adult zebrafish Langerhans cells arise from hematopoietic stem/progenitor cells

    Sicong He, Jiahao Chen ... Jin Xu
    Adult zebrafish Langerhans cells are derived from hematopoietic stem/progenitor cells but not Erythro-myeloid progenitors.

    Identification of phenotypically, functionally, and anatomically distinct stromal niche populations in human bone marrow based on single-cell RNA sequencing

    Hongzhe Li, Sandro Bräunig ... Stefan Scheding
    Single-cell transcriptomic profiling of human bone marrow non-hematopoietic cells provides the basis for a comprehensive understanding of the cellular complexity of the hematopoietic stem cell (HSC) microenvironment and the intricate stroma-hematopoiesis crosstalk mechanisms.

    Erythropoietin directly remodels the clonal composition of murine hematopoietic multipotent progenitor cells

    Almut S Eisele, Jason Cosgrove ... Leïla Perié
    Erythropoietin transiently remodels the hematopoietic stem and progenitor cells pool by directly inducing myeloid-erythroid-megakaryocyte-biased multipotent progenitor clones compensated at the population level by induction of myeloid-B-cell-dendritic-cell-biased clones.

    Loss of neurofibromin Ras-GAP activity enhances the formation of cardiac blood islands in murine embryos

    Amanda D Yzaguirre, Arun Padmanabhan ... Jonathan A Epstein
    Ras-GAP activity suppresses the hemogenic potential of the embryonic heart.

    Epigenetic regulation of hematopoiesis by DNA methylation

    Aniket V Gore, Brett Athans ... Brant M Weinstein
    Methylation of a key transcription factor gene by a de novo DNA methyltransferase assures the maintenance of hematopoietic stem cell fate.

    Uncovering perturbations in human hematopoiesis associated with healthy aging and myeloid malignancies at single-cell resolution

    Marina Ainciburu, Teresa Ezponda ... Felipe Prosper
    Single-cell transcriptomics reveals altered pathways, gene expression dynamics, and activation of transcriptional programs in human early hematopoiesis during healthy aging and myelodysplastic syndromes.
