Hematopoietic Stem Cell Development Requires Transient Wnt/ß-Catenin Activity
Researchers suggest that Wnt/ß-catenin activity is transiently required in the aorta-gonad-mesonephros (AGM) to generate long-term hematopoietic stem cells and to produce hematopoietic cells in vitro from AGM endothelial precursors. [J Exp Med] Abstract | Press Release

Subnetwork-Based Analysis of Chronic Lymphocytic Leukemia Identifies Pathways that Associate with Disease Progression
Researchers pursued a subnetwork-based analysis of gene expression profiles to discriminate between groups of patients with disparate risks for chronic lymphocytic leukemia progression. [Blood]
Abstract | Press Release

Hydroxyurea and a cGMP-Amplifying Agent Have Immediate Benefits on Acute Vaso-Occlusive Events in Sickle Cell Disease Mice
Scientists showed that inhibition of phosphodiesterase 9, an enzyme highly expressed in hematopoietic cells, amplified the cyclic guanosine monophosphate (cGMP)-elevating effects of hydroxyurea and suggest that this may represent a promising and more tissue-specific adjuvant therapy for this disease. [Blood] Abstract

Immunosuppressive CD14+HLA-DRlow/neg IDO+ Myeloid Cells in Patients following Allogeneic Hematopoietic Stem Cell Transplantation
Scientists identified a T-cell suppressive monocytic population that expands after allo- hematopoietic stem cell transplantation. [Leukemia] Abstract

EVI-1 Modulates Leukemogenic Potential and Apoptosis Sensitivity in Human Acute Lymphoblastic Leukemia
Researchers showed that ecotropic viral integration site-1 (EVI-1) is expressed not only in myeloid but also lymphoid leukemias and contributes to the leukemogenic potential and apoptosis resistance of acute lymphoblastic leukemia cells. [Leukemia] Abstract

Primary Hematopoietic Cells from DBA Patients with Mutations in RPL11 and RPS19 Genes Exhibit Distinct Erythroid Phenotype In Vitro
To develop a mechanistic understanding of Diamond-Blackfan anemia (DBA) pathogenesis, researchers studied CD34+ cells from peripheral blood of DBA patients carrying RPL11 and RPS19 ribosomal gene mutations and determined their ability to undergo erythroid differentiation in vitro.

Differential Regulation of CXCL5 by FGF2 in Osteoblastic and Endothelial Niche Cells Supports Hematopoietic Stem Cell Migration
Researchers suggest that the differential regulation of the chemokine CXCL5 between endosteal osteoblasts (OBs) and endothelial cells upon FGF2 treatment is involved in hematopoietic stem cell mobilization from the OB niche or bone marrow to peripheral blood. [Stem Cells Dev] Abstract

The Effects of Zoledronic Acid in the Bone and Vasculature Support of Hematopoietic Stem Cell Niches
The effects of zoledronic acid were investigated on bone marrow cell populations focusing on hematopoietic stem cells and the endosteal and vascular niches in bone. [J Cell Biochem] Abstract


Nilotinib in Imatinib-Resistant or Imatinib-Intolerant Patients with Chronic Myeloid Leukemia in Chronic Phase: 48- Month Follow-Up Results of a Phase II Study
The 48-month follow-up data for patients with chronic myeloid leukemia in chronic phase treated with nilotinib after imatinib resistance or intolerance on an international phase II study were analyzed. [Leukemia] Abstract

MK-0457, an Aurora Kinase and BCR-ABL Inhibitor, Is Active in Patients with BCR-ABL T315I Leukemia
MK-0457 was studied on a Phase I/II study in 77 patients with refractory hematologic malignancies. Researchers found that MK- 0457 has important activity in patients with leukemias expressing the highly resistant T315I BCR-ABL mutation. [Leukemia] Abstract

Brief Intensive Therapy for Older Adults with Newly Diagnosed Burkitt or Atypical Burkitt Lymphoma/Leukemia
Because cyclophosphamide is highly active in Burkitt lymphoma/leukemia (BL) and can be dose-escalated without stem-cell rescue, researchers designed a short, cyclophosphamide-intensive regimen without anthracyclines for patients older than 30 with untreated, non-HIV-associated BL/atypical BL. [Leuk Lymphoma] Abstract

American Society of Hematology Launches Multi-Million-Dollar Grant Program to Support Critical Blood Disease Research
The American Society of Hematology announced its commitment of $9 million over a three-year period to provide funding, in the form of bridge grants, for its hematologists whose vital research will not be accomplished due to the severe funding reductions for biomedical research. [American Society of Hematology] Press Release

Stem Cell Agency Commits $150 Million to Develop New Therapies
California’s stem cell agency, the California Institute for Regenerative Medicine approved $150 million in new funding to help move promising stem cell-based therapies from the laboratory research phase to clinical trials in people. [California Institute for Regenerative Medicine] Press Release

Cleveland BioLabs Signs Contract for Approximately $4 Million with Russian Ministry of Industry and Trade for Development of CBLB612
Cleveland BioLabs, Inc. announced that it has signed a contract valued at approximately $4 million, with the Ministry of Industry and Trade of the Russian Federation for development of CBLB612, a drug in development for stimulation of hematopoietic stem cell proliferation and mobilization. [Cleveland BioLabs, Inc.] Press Release

DACOGEN® Receives Positive Regulatory Recommendation in the European Union for Treatment of Acute Myeloid Leukemia
Janssen-Cilag International NV announced that the Committee for Medical Products for Human Use (CHMP) of the European Medicines Agency has granted a positive opinion recommending approval of DACOGEN® for injection. The CHMP is recommending that DACOGEN be indicated for the treatment of adult patients with newly diagnosed de novo or secondary acute myeloid leukemia, who are not candidates for standard induction chemotherapy.
