PUBLICATIONS(Ranked by impact factor of the journal)Investigators established a bcas2 knockout zebrafish model by using transcription activator-like effector nucleases. The bcas2-/- zebrafish showed severe impairment of hematopoietic stem and progenitor cells and their derivatives during definitive hematopoiesis. [Blood] Abstract Researchers developed a time-dependent assay to mimic ruxolitinib withdrawal in primary JAK2V617F and CALR mutant myelofibrosis patient samples and observed notable activation of spontaneous STAT signaling in JAK2V617F samples after drug washout. [Sci Adv] Full Article Cooperative Transcription Factor Induction Mediates Hemogenic Reprogramming The authors demonstrated that human fibroblasts can be reprogrammed into hemogenic cells by the same transcription factors. Induced cells displayed dynamic endothelial-to-hematopoietic transition transcriptional programs, generated hematopoietic progeny, possessed hematopoietic stem and progenitor cell surface phenotype, and repopulated immunodeficient mice for three months. [Cell Rep] Full Article | Graphical Abstract Scientists successfully established a mouse model of lung metastasis using luciferase-expressing MDA-MB-435s cells. In this model, recruitment of vascular endothelial growth factor receptor-1 (VEGFR1)+CD133+ hematopoietic progenitor cells was gradually increased in lung but gradually decreased after the formation of tumor colonies in lung. [J Cancer Res Clin Oncol] Abstract Resveratrol stimulated the ex vivo expansion of CD34+ cells, preserved more primitive hematopoietic stem and progenitor cells and maintained better biological function by alleviating intracellular reactive oxygen species level and cell apoptosis in cultures. [J Cell Biochem] Abstract A virus- and oncogene-free induced pluripotent stem cell reprogramming method was developed with cord blood-derived mononuclear cells and peripheral blood mononuclear cells from patients with genetic lung diseases. [Regen Med] Full Article CLINICAL RESEARCHResearchers showed that myeloablative haploidentical hematopoietic stem cell transplantation with ATG + granulocyte colony-stimulating factor was superior to chemotherapy as a postremission treatment in patients with int-risk AML during first complete remission. [Clin Cancer Res] Abstract The authors investigated the discriminative capacity of an augmented comorbidity/age index among 724 recipients of allogeneic hematopoietic cell transplantation from HLA-mismatched, haploidentical, and umbilical cord blood grafts between 2000 and 2013. [Biol Blood Marrow Transplant] Abstract Scientists analyzed samples from 113 acute myeloid leukemia patients in complete remission prior to HSC transplantation for the presence of clonal hematopoiesis-associated mutations. The results were correlated with clinical and biological data. [Bone Marrow Transplant] Abstract Subscribe to one of our other 19 science newsletters such as Cord Blood News & Cell Therapy News. | |

REVIEWSThe authors review how the link between arterialization and subsequent definitive multilineage hematopoietic program can be exploited to identify hemogenic endothelium enriched in lymphoid progenitors and aid in in vitro approaches to enhance the production of lymphoid cells and potentially HSCs from human pluripotent stem cells.

[Press release from Actinium Pharmaceuticals discussing research presented at the 60th Annual Meeting of the American Society of Hematology (ASH), San Diego] Press Release Gamida Cell Announces New Translational Data for Nicord® Gamida Cell Ltd. presented translational data for NiCord®, an investigational cell therapy in Phase III clinical development for allogeneic stem cell, or bone marrow, transplant. [Press release from Gamida Cell Ltd. discussing research presented at the 60th Annual Meeting of the American Society of Hematology (ASH), San Diego] Press Release Pluristem Presents Data from First Cohort in Ongoing Phase I Hematological Study Pluristem Therapeutics Inc. announced that the company presented data from the first cohort of patients in its ongoing Phase I clinical trial of PLX-R18 for the treatment of incomplete hematopoietic recovery following hematopoietic cell transplantation. [Press release from Pluristem Therapeutics Inc. discussing research presented at the 60th Annual Meeting of the American Society of Hematology (ASH), San Diego] Press Release Editas Medicine, Inc. announced results from experiments to demonstrate expanded CRISPR genome editing strategies in HSCs for the treatment of sickle cell disease and beta-thalassemia. [Press release from Editas Medicine, Inc. discussing research presented at the 60th Annual Meeting of the American Society of Hematology (ASH), San Diego] Press Release Early Clinical Trial Data Show Gene Therapy Reversing Sickle Cell Anemia Preliminary data from a pilot Phase I-II clinical trial testing the gene-addition therapy were presented by principal investigator Punam Malik, MD. She is a physician-scientist at the Cincinnati Children’s Cancer and Blood Diseases Institute and director of its Comprehensive Sickle Cell Center. [Press release from Cincinnati Children’s Hospital Medical Center discussing research presented at the 60th Annual Meeting of the American Society of Hematology (ASH), San Diego] Press Release The research points to new opportunities for preventing relapse after transplantation and determining which patients should be considered for lower-intensity chemotherapy in preparation for transplant.
