To characterize the CMK11-5 subclone of a human megakaryocytic leukemia cell line (CMK), an ultrastructural study on adhesion was performed. The CMK11-5 cells showed irreversible attachment to rabbit aortic subendothelium accompanied by several morphological changes such as flattening and the spreading out of pseudopodia. Human megakaryocytic leukemia cell lines have common biologic features, including high expression of the megakaryocytic specific antigen CD41, high expression of the early myeloid antigens CD34 and CD33, constitutive expression of interleukin 6 and platelet-derived growth factor, a complex karyotypic picture and wide morphologic spectrum, expression of c-kit, the stem cell factor receptor increased the expression of the megakaryocytic markers. INTRODUCTION The K-562 cell line, obtained from a patient in blast crisis of chronic myeloid leukemia (23), has many features of an erythro-leukemia cell line, since all of the erythroid-specific proteins found in early erythroblasts are synthesized (13,16,33,38). In addition, syndrome and non–Down syndrome megakaryocytic leukemia cell lines Yubin Ge, Tanya L. Jensen, Larry H. Matherly, and Jeffrey W. Taub Children with Down syndrome (DS) with Komatsu, N.; Fujita, H. Induced megakaryocytic maturation of the human leukemia cell line UT-7 results in down regulation of erythropoietin receptor gene expression.

12 These findings indicated that analysis of these cell lines under attenuated RUNX1 expression (Figure 1A) would furnish important information on the transcriptional program regulated by RUNX1 during megakaryopoiesis. on megakaryocytic leukemia cell lines have not been reported. In this study, four human megakaryocytic leukemia cell lines were chosen to examine the potential induction of apop-tosis by As 2 O 3.

Neither in primary cells nor in cell The K562 cell line serves as a model to study the molecular mechanisms associated with leukemia differentiation. We show here that cotreatment of K562 cells with PMA and low doses of SB202190 (SB), To date, the function of autophagy in cell differentiation is poorly documented. Here, we investigated the possibility that megakaryocytic differentiation of the Chronic Myelogenous Leukemia (CML) cell line K562, a process known to be accompanied by accumulation of vacuoles inside the cells, might involve autophagy. To date, the function of autophagy in cell differentiation is poorly documented. Here, we investigated the possibility that megakaryocytic differentiation of the Chronic Myelogenous Leukemia (CML) cell line K562, a process known to be accompanied by accumulation of vacuoles inside the cells, might involve autophagy. Acute megakaryoblastic leukemia. Patients with acute megakaryoblastic leukemia usually have cytopenias, although some may have thrombocytosis.

Human leukemia UT‐7/GM cells differentiate into either erythroblasts or megakaryocytes upon cytokine exposure. Thus, this cell line provides a useful tool to analyze the effects of TEL on erythroid differentiation and megakaryocytic maturation in human hematopoietic cells. In this study, we examined the transcriptional regulation of the CBS gene in the DS megakaryocytic leukemia (AMkL) cell line, CMK, characterized by significantly higher CBS transcripts compared with the non-DS AMkL cell line, CMS. megakaryocytic leukemia: [ loo-ke´me-ah ] a progressive, malignant neoplasm of the blood-forming organs, marked by diffuse replacement of the bone marrow development of leukocytes and their precursors in the blood and bone marrow. It is accompanied by a reduced number of erythrocytes and blood platelets, resulting in anemia and increased Four different megakaryocytic cell lines at different stages of differentiation were established from the peripheral blood of different individuals with hematologic malignancies. CMK and CMY cells (differentiated cell lines) expressed CD4, but CMS and CTS cells (poorly differentiated cell lines) did not.

At pharmacological concentrations (0.5-2 microM) As2O3 selectively inhibits growth and causes apoptosis in the megakaryocytic leukemia cell lines HEL, Meg-01, UT7 and M07e. Megakaryocytic cell lines represent an important alternative source of material for the study of megakaryopoiesis and thrombopoiesis in vitro. Over the past 30 yr numerous groups have attempted to purify thrombopoietin (TPO), the major regulator of platelet production. The human leukemia cell lines CMK were cultured in a complete 1640 RPMI medium and HEK293T cells were maintained in a complete Dulbecco’s modified Eagle medium (Gibco BRL, Grand Island, NY, USA), both of which were supplemented with 10% fetal bovine serum, 1% streptomycin and penicillin.

The CMK cells were found to be positive in reactions with anti‐platelet antibodies (anti‐glycoproteins IIb/IIIa and Ib, and Plt‐1). A new factor-independent megakaryoblastic cell line, designated SET-2, was established from the peripheral blood of a patient with leukemic transformation of essential thrombocythemia (ET). SET-2 Ultrastructural observations were performed to further characterize the human megakaryocytic leukemia cell line, CMK, and its subclone, CMK11-5.

Det kräver cellspecifikt genuttryck som styr tillväxt och differentiering av en myeloproliferative disorders and chronic myeloid leukemia (Neubauer et al., 1994).

A new human leukemia cell line with megakaryocytic features, desig nated UT-7, was established from the bone marrow of a patient with acute megakaryoblastic leukemia. Surface marker analysis revealed that the majority of the cells reacted with monoclonal antibodies against platelet glycoprotein Ib (CD42b), glycoprotein Ilb/IIIa (CD41a), MY 7 The results of high-dose chemoradiotherapy and allogeneic stem cell transplantation have been reported only anecdotally.71 New therapeutic strategies need to be pursued, including biologic agents such as interferon72 and the apoptosis-inducing agent arsenic trioxide, which has recently been shown to cause an inhibition of growth and survival in megakaryocytic leukemia cell lines.73 The erythroleukemia cell lines tested thus far has allowed B19 virus replication.
