    A Non-Canonical Enzymatic Function of PIWIL4 Maintains Genomic Integrity and Leukemic Growth in AML

    Researchers reported that PIWIL4 was overexpressed in AML patients and was essential for leukemic stem cell function and AML growth, but dispensable for healthy human hematopoietic stem cells.

    Abstract

    Hematopoietic Jagged1 Is a Fetal Liver Niche Factor Required for Functional Maturation and Engraftment of Fetal Hematopoietic Stem Cells

    Through the use of single-cell analysis and transplantation assays, investigators provided evidence of Jagged1 as a novel niche factor for fetal liver HSCs.

    Abstract

    Single-Center Retrospective Study Assessing the Efficacy and Safety of BeEAM (Bendamustine, Etoposide, Cytarabine, Melphalan) As Conditioning Regimen for Autologous Hematopoietic Stem Cell Transplantation

    This observational retrospective single-center study reported the efficacy and safety of the BeEAM regimen. 55 patients with diffuse large B cell lymphoma, Hodgkin lymphoma, mantle cell lymphoma, or follicular lymphoma were included.
