TOP STORY
Early Stem Cell Transplants Evaluated for Non-Hodgkins Lymphoma Patients at High Risk of Early Relapse
Performing early stem cell transplants in patients with aggressive non-Hodgkin’s lymphoma does not improve overall survival in high-risk patients. But early transplantation does appear to be beneficial among a small group of patients who are at the very highest risk.

LABORATORY RESEARCH

In Vivo Leukemogenic Potential of an Interleukin-7 Receptor α Chain Mutant in Hematopoietic Stem and Progenitor Cells
Researchers found that ectopic expression of INS alone in hematopoietic stem/progenitor cells caused myeloproliferative disorders, whereas expression of INS in combination with a Notch1 mutant led to the development of much more aggressive T acute lymphoblastic leukemia than with wild-type interleukin-7 receptor α chain. [Blood] Abstract

Thrombopoietin Promotes Non-Homologous End Joining DNA Repair in Hematopoietic Stem Cells through Specific Activation of Erk and NF-κB Pathways and Their Target IEX-1
Scientists showed that thrombopoietin (TPO) specifically triggers Erk and NF-κB pathways in mouse hematopoietic stem and progenitors cells. These pathways are both required for TPO-mediated increase in double-strand break repair. [Blood] Abstract

In Vivo Generation of Decidual Natural Killer Cells from Resident Hematopoietic Progenitors
Scientists identified Natural Killer precursors in decidua and uterus of pregnant mice. These precursors underwent rapid in situ differentiation and large proportions of proliferating immature Natural Killer cells were present in decidua and uterus as early as gestation day 4,5. [Haematologica] Abstract

ZNF16 (HZF1) Promotes Erythropoiesis and Megakaryocytopoiesis via Its Regulation on c-KIT Gene
The authors investigated ZNF16’s effect in erythroid and megakaryocytic differentiation of hematopoietic stem/progenitor cells (HSPCs) and the mechanisms. They observed up-regulation of ZNF16 during erythroid and megakaryocytic differentiation of the CD34+ HSPCs, and demonstrated that ZNF16 promotes erythroid and megakaryocytic differentiation by gain-of-function and loss-of-function experiments. [Biochem J] Abstract

Merging Concepts – Coupling an Agent-Based Model of Hematopoietic Stem Cells with an ODE Model of Granulopoiesis
Investigators propose a combination of an ordinary differential equation (ODE) model of human granulopoiesis and an agent-based model of hematopoietic stem cell organization. [BMC Syst Biol]

Circulating Hematopoietic Progenitor Cells are Decreased in COPD
Researchers measured circulating levels of endothelial progenitor cells and hematopoietic progenitor cells in subjects with COPD and to determine if progenitor levels correlated with disease severity and the presence of emphysema. [COPD-J Chronic Obstr Pulm Dis] Abstract

CLINICAL RESEARCH

The First Tissue-Engineered Airway Transplantation: 5-Year Follow-Up Results
In 2008, the first transplantation of a tissue-engineered trachea in a human being was done to replace an end-staged left main bronchus with malacia in a 30-year-old woman. Researchers report five year follow-up results. [Lancet] Abstract

The Gene Signature in CCAAT-Enhancer-Binding Protein α Dysfunctional Acute Myeloid Leukemia Predicts Responsiveness to Histone Deacetylase Inhibitors
The authors defined the C/EBPα signature characterized by a set of genes upregulated upon C/EBPα activation. They analyzed expression of the C/EBPα signature in a cohort of 525 acute myeloid leukemia patients and identified a subset of samples characterized by low expression of this signature. [Haematologica] Abstract

Mobilization and Engraftment of Peripheral Blood Stem Cells in Healthy Related Donors >55 Years Old
Researchers analyzed the influence of age on the results of mobilization of peripheral blood stem cells in healthy donors as well as on the engraftment and outcome of hematopoietic stem cell transplantation. [Cytotherapy] Abstract

REVIEWS
Contribution of the Local RAS to Hematopoietic Function: A Novel Therapeutic Target
Researchers outlined the known functions of the local bone marrow (BM) renin-angiotensin system (RAS) within the context of primitive and definitive hematopoiesis as well as modification of BM recovery by administration of exogenous ligands of the RAS. Targeting the actions of local RAS molecules could represent a valuable therapeutic option for the management of BM recovery after injury as well as neoplastic disorders.

INDUSTRY NEWS
University of Louisville Researchers Sign Global Licensing Agreement
The University of Louisville announced that researcher Dr. Suzanne Ildstad, representing Regenerex LLC, has entered into a license and research collaboration agreement with Novartis to provide access to stem cell technology that has the potential to help transplant patients avoid taking anti-rejection medicine for life and could serve as a platform for treatment of other diseases.

Pharmalink Receives US Orphan Drug Designation for Busulipo™, Its Novel Oncology Product for Bone Marrow Transplantation
Pharmalink AB announced its product Busulipo™, a conditioning agent for use in cancer patients prior to hematopoietic stem cell transplantation, has received orphan drug designation from the US Food and Drug Administration. [Pharmalink AB] Press Release
