We studied the cell kill induced by granulocyte-macrophage colony-stimulating factor (GM-CSF ) fused to Diphtheria Toxin (DT-GM-CSF ) in acute myeloid leukemia (AML) samples and in populations of normal primitive hemopoietic progenitor cells. AML samples from three patients were incubated in vitro with 100 ng/mL DT-GM-CSF for 48 hours, and AML cell kill was determined in a proliferation assay, ...

We have devised a method of evaluation, in terms of Goldblatt units (GU), of the data obtained in various laboratories for the excretion of renin from canine and human kidneys. An average value of 1.3 X 10" GU/min g" normal renal tissue resulted for both dog and man. A blood pressure increase of 18—45 mm Hg was induced in normal or nephrectomized, conscious or anesthetized dogs by the continuou...

To explore the pathogenesis of marrow failure in B-cell type chronic lymphocytic leukemia (B-CLL), we have examined the production of interleukin-6 (IL-6). granulocyte colony-stimulating factor (G-CSF), and granulocyte-macrophage CSF (GM-CSF) by the adherent cell population of bone marrow (BM) derived from B-CLL patients and their capacity to support hematopoietic cell proliferation. Lipopolysa...

Hematopoietin-1 (H-1) was purified from the human cell line 5637 and two amino acid sequences were observed in the preparation. One sequence was identical to that of interleukin 1 alpha (IL 1 alpha) and the other to that of IL 1 beta. The action of recombinant IL 1 alpha and other hematopoietic growth factors was studied using (a) a high proliferative potential colony-forming cell assay that us...

objective: despite of many benefits, umbilical cord blood (ucb) hematopoietic stem cell (hsc) transplantation is associated with low number of stem cells and slow engraftment; in particular of platelets. so, expanded hscs and co-transfusion of megakaryocyte (mk) progenitor cells can shorten this period. in this study, we evaluated the cytokine conditions for maximum expansion and mk differentia...

Human bone marrow cells were sequentially fractionated by three negative selection steps to remove adherent cells and Fc receptorbearing cells, followed by immune adsorption (panning) to deplete maturing cells that react with a panel of monoclonal antibodies. This nonadherent Fc receptor and antibody negative fraction could be further enriched by a positive selection "panning" step, using an an...

Introduction: The current study investigated the combination of high Z atoms (iodine-, platinium-based drugs) with using low energy irradiation (120kvp) in Anaplastic Thyroid cancer cells.Materials and Methods: For this purpose, eight groups were designed: control (CNT), different concentrations of Iodine contrast media (ICM),  irradiation with various doses, Cis-platin (CDDP) with different c...
