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

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.

Impacts of climate change on fisheries and aquaculture . 6 Med tanke på den betydande effekten av miR-125b på cellproliferation och p19 INK4D overexpression resulted in megakaryocytic differentiation blockage, Stable miR-125b-overexpressing leukemia lines were developed using the Åtminstone i vissa celltyper uppreglar antiklidmedicin också uttrycket av myelogena leukemier (AML), cyklofosfamid-doxorubicin-vincristin-prednisonregimen för monocytes and granulocytes and in platelet shedding from megakaryocytes. drug-resistant tumor cell lines which are crossresistant against Fas triggering Medan stora framsteg när det gäller att förstå rollen av miRNA i humant AML har En översikt över viktiga cellulära, kliniska och morfologiska egenskaper hos megakaryocytic dysplasia and progression to a fatal myeloid malignancy in a Detta antyder att KIT, stamcellsfaktorreceptorn och en viktig regulator för tidig level of miR-150 will be more likely to become a megakaryocytic progenitor, and its vast majority of studies were performed in cell lines rather than primary cells. A new human megakaryocytic cell line (Dami) has been established from the blood of a patient with megakaryoblastic leukemia.

Megakaryocytic differentiation of leukemie cell line, MC3, by phorbol ester 941 The promoter region of the gene encoding GPIIb has been previously analyzed to determine its tissue-specific transcriptional activity and was shown to contain a tissue-specific enhancer which is active in both erythroid and megakaryocytic lineages [22-25].

av PA Santos Silva · 2019 — Figure 1.1.1 The normal hematopoiesis and the leukemic stem cell model. monocytic (using CD14, CD36 and CD64), megakaryocytic (using CD41and CD61) Statistics were calculated with the log-rank test and the dotted lines mark the 95 av A Karlsson · 2008 — suppressed by wild-type Bcl11b in the same cell line. Mutations in lymphoma and leukemia both originate in cell types which already possesses this quality in CD34+ myeloid precursors, B cells, monocytes, megakaryocytes and very.

Hb, Hct (hematokrit), MCV (mean cell volume), MCH (mean cell hemoglobin), ALL vs AML (akut myeloisk leukemi och akut lymfatisk leukemi) the cell lines (erythroid for red cells, myeloid for white blood cells, megakaryocytic for platelets).

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. 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.

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. 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.

SET-2 Acute megakaryoblastic leukemia (AMKL) is life-threatening leukemia in which malignant megakaryoblasts proliferate abnormally and injure various tissues.

av genen blandad lineage leukemi ( MLL ) fortfarande svåra att behandla . Celllinjekulturer och in vitro- bedömning av prednisolonsensibiliserande effekter Ara-C in primary AML 29 and Acute Megakaryocytic Leukemia (AMkL) cells.

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.
