    CCR5 Maintains Macrophages in the Bone Marrow and Drives Hematopoietic Failure in a Mouse Model of Severe Aplastic Anemia

    Interferon gamma was required for increased expression of the chemokine receptor CCR5 on dysfunctional macrophage. CCR5 antagonism in murine severe aplastic anemia improved survival, correlating with increased platelets and significantly increased platelet-biased CD41hi HSCs.

    Slc20a1b Is Essential for Hematopoietic Stem/Progenitor Cell Expansion in Zebrafish

    Researchers characterized a hematopoiesis defective zebrafish mutant line named smu07, which was obtained from our previous forward genetic screening, and found the hematopoietic stem and progenitor cell expansion deficiency in the mutant.

    Abstract

    Multistage Feedback Driven Compartmental Dynamics of Hematopoiesis

    To characterize the dynamics following different types of perturbations, the authors investigated a model representing hematopoiesis as a sequence of compartments covering all maturation stages – from stem to mature cells – where feedback regulated cell production to ongoing necessities.

    Outcome of T-Cell-Replete Haploidentical Stem Cell Transplantation Improves with Time in Adults with Acute Lymphoblastic Leukemia: A Study from the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation

    The Acute Leukemia Working Party/European Society for Blood and Marrow Transplantation registry was used to evaluate the outcomes of adult patients with acute lymphoblastic leukemia who underwent hematopoietic cell transplantation during 2011 through 2015 and compared them with the outcomes of those who underwent transplantation during 2016 through 2018.
