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.

Patients with acute megakaryoblastic leukemia usually have cytopenias, although some may have thrombocytosis. Dysplastic features are often present in all cell lines. Diagnosis requires the presence of at least 20% blasts, of which at least 50% must be of megakaryocyte origin. The human CML cell line K562 has been used extensively as a model for the study of leukemia differentiation.1-3 K562 cells can undergo differentiation in both megakaryocytic and eryth-roid lineages depending on the stimulus. Phorbol esters such as PMA stimulated megakaryocytic differentiation,4-7 a process A new human megakaryocytic cell line (Dami) has been established from the blood of a patient with megakaryoblastic leukemia.

We found that particles derived from CMK11-5 cells had cytoplasmic projections and no nucleus, and that some particles contained alpha granules. Megakaryocytic Cell Line, UT-7/TPO By Norio Komatsu, Masae Kunitama, Minami Yamada, UT-7 is a human megakaryoblastic leukemia cell line with absolute dependence on interleukin-3, granulocyte megakaryocytic-specific cell lines in transfection experiments would be very helpful to address this question. The human megakaryoblastic leukemia cell line MEG-01 was erythro-megakaryocytic leukemia cell lines responded to TPO with increased proliferation, TPO strongly augmented the growth of several constitutively cytokine-dependent cell lines (HU-3, M-07e, M-MOK, OCI-AML-1, TF-1) which can be made TPO-dependent and used as bioassays. 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.

PubMed Google Scholar ERG induces megakaryoblastic leukemia in mice. Having established cell lines with a megakaryocytic phenotype, we examined the leukemogenic potential of ERG in vivo.HPCs transduced with ERG or vector control were transplanted into sublethally irradiated syngeneic mice 48 h after transduction. Our results showed that As2O3, at concentrations of 0.1-2.0 microM, causes a dose- and time-dependent inhibition of survival and growth in all four megakaryocytic leukemia cell lines studied. In contrast, As2O3 at similar concentrations had no effects on either viability or growth of the nonmegakaryocytic leukemia cell line HL60 and two human breast cancer cell lines, ZR75 and MCF7.

Eighteen human and three animal cell lines that express some megakaryocytic features have been described in the literature. A new megakaryoblastic cell line (CMK), which also exhibits erythroid and myeloid markers, was established from a Down's syndrome patient suffering from acute megakaryoblastic leukaemia. 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.

This manuscript describes the expression of MPL on a number of AML and other leukemia and lymphoma cell lines and reports how eltrombopag affects the proliferation, apoptosis and differentiation of these cell lines. 1991-12-31 · To assess the potent effect of erythroid differentiation factor (EDF) on megakaryocytopoiesis, effect of EDF on megakaryocytic differentiation of L805… To further clarify whether Mkl1 mRNA levels increase during megakaryocytic maturation as opposed to simply being expressed maximally in megakaryocytes versus other blood cell types, we cultured murine BM cells with TPO for 1 day, sorted c-kit + CD41 + megakaryocytic progenitors (day 1), and differentiated them into mature megakaryocytes in vitro (day 2, day 5). 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.
