    Bone Marrow Niche ATP Levels Determine Leukemia-Initiating Cell Activity via P2X7 in Leukemic Models

    The authors showed that ATP levels were markedly increased in the bone marrow niches of mice with acute myeloid leukemia, and leukemia-initiating cells preferred to localize to the endosteal niche with relatively high ATP levels, as indicated by a sensitive ATP indicator.

    Targeted Inhibition of Cooperative Mutation- and Therapy-Induced AKT Activation in AML Effectively Enhances Response to Chemotherapy

    Scientists demonstrated that the inv(16)/KITD816Y AML mouse model exhibited constitutive activation of PI3K/AKT signaling, which was enhanced by chemotherapy-induced DNA damage through DNA-PK-dependent AKT phosphorylation.

    Loss of Nupr1 Promotes Engraftment by Tuning the Quiescence Threshold of Hematopoietic Stem Cell Repository via Regulating p53-Checkpoint Pathway

    Investigators unveiled that deletion of Nupr1, a gene preferentially expressed in hematopoietic stem cells (HSCs), activated the quiescence HSCs under homeostatic status, which conferred engraftment competitive advantage on HSCs without compromising their stemness and multi-lineage differentiation abilities in serial transplantation settings.

    Machine Learning of Hematopoietic Stem Cell Divisions from Paired Daughter Cell Expression Profiles Reveals Effects of Aging on Self-Renewal

    The authors combined single-cell profiling with machine learning and in vivo functional studies to explore how hematopoietic stem cell divisions patterns evolve with age.

    A Splicing Factor Switch Controls Hematopoietic Lineage Specification of Pluripotent Stem Cells

    Researchers showed that pervasive and dynamic alternative splicing takes place during hematopoietic development of human pluripotent stem cells. They identified a splicing factor switch that occurs during the differentiation of mesodermal cells to endothelial progenitor cells.

    A Scalable Suspension Platform for Generating High-Density Cultures of Universal Red Blood Cells from Human Induced Pluripotent Stem Cells

    The authors developed a scalable suspension agitation culture platform for differentiating human induced pluripotent stem cell-microcarrier aggregates into functional red blood cells and have demonstrated scalability of the process starting with six well plates and finally demonstrating in 500 mL spinner flasks.

    Hematopoietic Stem Cell Transplantation for Adults with Relapsed Acute Promyelocytic Leukemia in Second Complete Remission

    Scientists retrospectively compared outcomes of a large series of adult patients with APL in CR2 receiving alloHSCT or autoHSCT reported to the European Society for Blood and Marrow Transplantation from January 2004 to December 2018.
