抄録 <p>A new myeloid cell line, MTT-95, was established from the bone marrow of a patient with acute myelogenous leukemia (AML, M7). MTT-95 cells differentiate into mature basophilic cells in culture medium with no chemical component or cytokine. Surface phenotypes were as follows: CD11b 79.3%, CD13 92.4%, CD33 99.8%, CD34 87.9%, CD41a 77.6% and HLA-DR 0.3%. MTT-95 cells were strongly positive for glycoprotein IIb/IIIa by immunohistochemical staining and revealed metachromatic granules. MTT-95 cells seem to possess characteristics of both megakaryocytes and basophils. These findings suggest that MTT-95 cells are basophil progenitors. MTT-95 cells might be useful in the study not only of the biological aspects of basophils, but also of the diversities of AML (M7).</p>

抄録 <p>A new myeloid cell line, MTO-94, was established from the bone marrow of a patient with myelodysplastic syndrome (MDS). MTO-94 cells matured in culture medium without the addition of growth factors, and yielded neutrophils with pseudo-Pelger Hue&#776;t anomaly or hypersegmentation until 6 months. Ten months after the start of cell cultivation, MTO-94 consisted of myeloblasts. Surface phenotypes were as follows: CD7 90.3%, CD13 99.6%, CD33 75.6%, HLA-DR 96.3% and CD34 0.9%. The karyotype was 46, XY, i(17q). The proliferation of MTO-94 cells was enhanced by rhlL-3, G-CSF, rhGM-CSF and rhSCF but not by rhlL-6 and erythropoietin. MTO-94 cells with i(17q) might be useful in the study of biological aspects of not only MDS, but also hematological malignancies with i(17q) as the sole chromosomal anomaly.</p>
