Lineage infidelity of a human myelogenous leukemia cell line.
We have analyzed the organization and expression of the immunoglobulin heavy and light chain gene in the human myeloblastic leukemic sublines, ML1, ML2, and ML3, and in the human myeloid leukemic cell lines, HL-60, U937, THP1, and K562. ML1, ML2, and ML3 cells, despite a predominant granulocytic phenotype, express a rearrangement of the immunoglobulin heavy chain gene that typically occurs duri...
متن کاملLineage infidelity in acute leukemia.
Blast cells from 20 patients with acute leukemia (13 diagnosed myeloblastic and 7 as lymphoblastic, using the FAB classification) were studied using antibodies to lineage-specific differentiation markers. The phenotypic findings were usually consistent with the clinical diagnosis. However, examples were encountered where individual blast cells had a cytoplasmic marker of one lineage and a surfa...
متن کاملHuman chronic myelogenous leukemia cell-line with positive Philadelphia chromosome.
A cell-line derived from a patient with chronic myelogenous leukemia (CML) is described. The new cell-line, which has over 175 serial passanges in a 3 1/2-yr period, has the following characteristics: (1) CML cells started to proliferate actively since they were first incubated in culture media. A threefold increase in the total number of cells was observed during the first seven passages; the ...
متن کاملDevelopment of NK cell expansion methods using feeder cells from human myelogenous leukemia cell line
BACKGROUND Natural killer (NK) cells constantly survey surrounding tissues and remove newly generated cancer cells, independent of cancer antigen recognition. Although there have been a number of attempts to apply NK cells for cancer therapy, clinical application has been somewhat limited because of the difficulty in preparing a sufficient number of NK cells. Therefore, ex vivo NK cell expansio...
متن کاملCharacterization of a vitamin D3-resistant human chronic myelogenous leukemia cell line.
A variant of the chronic myelogenous leukemia cell line, RWLeu-4, that is resistant to the antiproliferative effects of vitamin D3 was established. Although RWLeu-4 proliferation is inhibited by 1 nmol/L vitamin D3, the resistant cells (JMRD3) continue to proliferate in the presence of 100 nmol/L vitamin D3. Both cells express similar patterns of differentiation-specific antigens after treatmen...
