Bile Acid Supports the Production of Blood Stem Cells
Researchers showed that bile acid is transferred from the mother to the fetus via the placenta to enable the fetus to produce blood stem cells. [Press release from Lund University discussing online prepublication in Cell Stem Cell] Press Release | Abstract | Graphical Abstract
UM171 & UM729 - Get the Authentic Small Molecules for Ex Vivo Expansion of Human HSCs
PUBLICATIONS (Ranked by impact factor of the journal)
miR-126 Regulates Distinct Self-Renewal Outcomes in Normal and Malignant Hematopoietic Stem Cells
To investigate miRNA function in human acute myeloid leukemia (AML) stem cells (LSC), scientists generated a prognostic LSC-associated miRNA signature derived from functionally validated subpopulations of AML samples. [Cancer Cell] Full Article | Graphical Abstract

Tetraspanin CD37 Protects against the Development of B Cell Lymphoma
Scientists provided evidence that deficiency of tetraspanin superfamily member CD37, which is important for B cell function, induces the development of B cell lymphoma. [J Clin Invest] Full Article

HIF-1α Regulates the Interaction of Chronic Lymphocytic Leukemia Cells with the Tumor Microenvironment
The authors found that in chronic lymphocytic leukemia (CLL) hypoxia-inducible transcription factors (HIF)-1α is a novel regulator of the interaction of CLL cells with protective leukemia microenvironments, and is in turn regulated by this interaction in a positive feedback loop that promotes leukemia survival and propagation. [Blood] Abstract

The Dual MEK/FLT3 Inhibitor E6201 Exerts Cytotoxic Activity against Acute Myeloid Leukemia Cells Harboring Resistance-Conferring FLT3 Mutations
The authors investigated the anti-leukemia activity of a MEK1 and FLT3 dual inhibitor, E6201, in acute myeloid leukemia (AML) cells resistant to FLT3 inhibition. They found that E6201 exerted profound apoptogenic effects on AML cells harboring resistance-conferring FLT3 mutations. [Cancer Res] Abstract

Epigenetic Regulation of Hematopoiesis by DNA Methylation
Investigators showed that DNA methyltransferase 3bb.1 is essential for maintenance of hematopoietic stem and progenitor cell (HSPC) fate as part of an early Notch-runx1-cmyb HSPC specification pathway in the zebrafish. [eLife] Full Article

Diet-Induced Obesity in Mice Diminishes Hematopoietic Stem and Progenitor Cells in the Bone Marrow
Researchers studied how diet-induced obesity affects hematopoietic stem and progenitor cell population dynamics in the bone marrow. [FASEB J] Abstract | Full Article

CD45RA, a Specific Marker for Leukemia Stem Cell Sub-Populations in Acute Myeloid Leukemia
Scientists investigated the potency of CD45RA to specifically identify leukemic stem cells (LSCs) and hematopoietic stem cells and improve LSC quantification. [Br J Haematol] Abstract

MPT0B169, a New Antitubulin Agent, Inhibits Bcr-Abl Expression and Induces Mitochondrion-Mediated Apoptosis in Nonresistant and Imatinib-Resistant Chronic Myeloid Leukemia Cells
Researchers investigated the antitumor effect and mechanism of MPT0B169, a new antitubulin agent, in K562 chronic myeloid leukemia cells and their derived imatinib-resistant cells, IMR2 and IMR3. IMR2 and IMR3 cells showed complete resistance to imatinib-induced growth inhibition and apoptosis. [PLoS One] Full Article


Allogeneic T Cells that Express an Anti-CD19 Chimeric Antigen Receptor Induce Remissions of B-Cell Malignancies that Progress after Allogeneic Hematopoietic Stem-Cell Transplantation without Causing Graft-versus-Host Disease
Researchers conducted a clinical trial of allogeneic T cells genetically engineered to express a chimeric antigen receptor (CAR) targeting the B-cell antigen CD19. Patients with B-cell malignancies that had progressed after allogeneic hematopoietic stem-cell transplantation received a single infusion of CAR T cells. [J Clin Oncol] Abstract | Press Release

Association of Acute Myeloid Leukemia’s Most Immature Phenotype with Risk Groups And Outcomes
The authors analyzed the clinical utility of a novel assay for putative leukemia stem cells in a large prospective cohort. The leukemic clone’s most primitive hematopoietic cellular phenotype was prospectively identified in 109 newly-diagnosed acute myeloid leukemia patients, and correlated with clinical risk groups and outcomes. [Haematologica] Abstract

The Effects of Proliferation and DNA Damage on Hematopoietic Stem Cell Function Determine Aging
The authors examine the evidence that links proliferation of hematopoietic stem cells with aging, which leads to functional changes in the hematopoietic system. [Dev Dyn] Abstract

Kiadis Pharma and the Leukemia & Lymphoma Society Enter Partnership for the Development of ATIR101™ in ALL and AML Patients
Kiadis Pharma N.V. announced that it has entered into a partnership with The Leukemia & Lymphoma Society (LLS) under which LLS will fund the Phase II development of Kiadis Pharma’s lead product, ATIR101™, through an equity investment of approximately $1 million. [Kiadis Pharma] Press Release

NUI Galway Launch €6 Million Robotic Stem Cell Production Project
NUI Galway’s Regenerative Medicine Institute has launched a new €6 million research project AUTOSTEM to develop pioneering manufacturing systems for stem cell therapy. Funded by the EU Horizon 2020 program, AUTOSTEM will go a long way towards meeting the demand for these new treatments, by transforming the way stem cells are manufactured. [National University of Ireland, Galway] Press Release
