SCIENCE NEWS Theory of Single Stem Cell for Blood Components Challenged Components of the blood or hematopoietic system derive from stem cell subtypes rather than one single stem cell that gives rise to all the different kinds of blood cells equally. [Press release from the Baylor College of Medicine discussing the online prepublication in Cell Stem Cell] Stem Cells: Home of HIV? Human immunodeficiency virus (HIV) can infect bone marrow cells – including, possibly, hematopoietic stem cells, according to a study published online.

CURRENT PUBLICATIONS LABORATORY RESEARCH HIV-1 Infects Multipotent Progenitor Cells Causing Cell Death and Establishing Latent Cellular Reservoirs Here researchers used CD34+ cells from infected people as well as in vitro studies of wild-type HIV to show infection and killing of CD34+ multipotent hematopoietic progenitor cells. [Nat Med] Endothelial Cells Are Essential for the Self-Renewal and Repopulation of Notch-Dependent Hematopoietic Stem Cells Researchers have developed angiogenic models to demonstrate that endothelial cell-derived angiocrine growth factors support in vitro self-renewal and in vivo repopulation of authentic long-term hematopoietic stem cells. [Cell Stem Cell] Distinct Hematopoietic Stem Cell Subtypes Are Differentially Regulated by Transforming Growth Factor-Beta1 This study demonstrates definitive isolation of lineage-biased hematopoietic stem cells subtypes and contributes to the fundamental change in view that the hematopoietic system is maintained by a continuum of hematopoietic stem cells subtypes, rather than a functionally uniform pool. [Cell Stem Cell] Hematopoietic Progenitor Cell Regulation by CD4+CD25+ T Cells Together these findings illustrate that both recipient and donor regulatory T cells can influence hematopoietic progenitor cell activity post-transplant and that these cells can alter responses outside the adaptive and innate immune systems. [Blood] Expression of the Cytoplasmic NPM1 Mutant (NPMc+) Causes the Expansion of Hematopoietic Cells in Zebrafish These results are likely to be relevant to human NPMc+ acute myeloid leukemia, where the observed NPMc+ multilineage expression pattern implies transformation of a multipotent stem or progenitor cell. [Blood] Rational Design of a Fully Active, Long-Acting PEGylated Factor VIII for Hemophilia A Treatment Site-specifically PEGylated FVIII has the potential to be a long-acting prophylactic treatment while being fully efficacious for on-demand treatment for hemophilia A patients. [Blood] Mutant Ikzf1, KrasG12D, and Notch1 Cooperate in T Lineage Leukemogenesis and Modulate Responses to Targeted Agents Together, these studies identify a genetic pathway involving Ikzf1, KrasG12D, and Notch1 in T lineage leukemogenesis, reveal unexpected diversity in Ras-regulated signaling networks, and define biomarkers of drug responses that may inform treatment strategies. [Proc Natl Acad Sci USA] SHIP1 Inhibition Increases Immunoregulatory Capacity and Triggers Apoptosis of Hematopoietic Cancer Cells SHIP1 inhibitors represent a novel class of small molecules that have the potential to enhance allogeneic transplantation, boost blood cell production, and improve the treatment of hematologic malignancies. [J Immunol] Congenic Mice Confirm That Collagen X Is Required for Proper Hematopoietic Development These data support a model where endochondral ossification-specific collagen X contributes to the establishment of a hematopoietic niche at the chondro-osseous junction. [PLoS ONE] CLINICAL RESEARCH Phase I/II Study of Combination Therapy With Sorafenib, Idarubicin, and Cytarabine in Younger Patients With Acute Myeloid Leukemia The purpose of this study was to determine the efficacy and toxicity of the combination of sorafenib, cytarabine, and idarubicin in patients with acute myeloid leukemia younger than age 65 years. [J Clin Oncol] Relapse and Late Mortality in 5-Year Survivors of Myeloablative Allogeneic Hematopoietic Cell Transplantation for Chronic Myeloid Leukemia in First Chronic Phase Recipients of allogeneic hematopoietic cell transplantation for chronic myeloid leukemia in first chronic phase who remain in remission for at least 5 years have favorable subsequent long-term survival, and their mortality rates eventually approach those of the general population. [J Clin Oncol] Effect of Age on Outcome of Reduced-Intensity Hematopoietic Cell Transplantation for Older Patients With Acute Myeloid Leukemia in First Complete Remission or With Myelodysplastic Syndrome To define prognostic factors impacting long-term outcomes of reduced-intensity conditioning regimens in patients older than age 40 years with acute myeloid leukemia in first complete remission or myelodysplastic syndrome and to determine the impact of age, researchers analyzed data from the Center for International Blood and Marrow Transplant Research.

INDUSTRY NEWS Bayer Settles With Novartis Over Hemophilia-Treatment Patent Bayer AG, Germany’s largest drugmaker, settled a lawsuit brought by Novartis AG and Novo Nordisk A/S that claimed Bayer infringed a patent related to treatment of the bleeding disorder hemophilia. [BusinessWeek] Canadian Budget Light on New Research Dollars Relief was the order of the day for Canadian scientists as the federal government brought down its fiscal blueprint for 2010-11. [ScienceInsider] In Annual Rite, Chinese Science Showered with Riches At the opening session of the National People’s Congress, officials announced that the science and technology budget will rise 8% to 163.3 billion RMB ($24 billion) in 2010.
