Human acute myeloblastic leukaemia

ML-1 is one of three celll lines isolated in 1978 from the peripheral blood of a 24 year old male patient with acute myeloblastic leukaemia. The cells can convert to more mature cells by the use of DMSO. The Y chromosome could not be detected in this cell line by short tandem repeat (STR)-PCR analysis when tested at ECACC. It is a known phenomenon that due to the increased genetic instability of cancer cell lines the Y chromosome can be rearranged or lost resulting in lack of detection. The cell line is identical to the source provided by the depositor based on the STR-PCR analysis.

ML-1 has been used to compare the cell response to mafosfamide cyclohexylamine salt, 4-hydro-peroxy-cyclophosphamide and β-D-glucose-isophosphoramide mustard, which are oxazaphosphorine agents.[1]

RPMI 1640 (R0883) + 2mM L-Glutamine (G7513) + 10% FBS (F2442)

Maintain cultures between 2-9 x100,000 cells/ml; 5% CO₂; 37°C. Freeze in 10% DMSO + 90% FBS. Immediately after resuscitation, pellet cells by centrifugation at 150 x g for 5 minutes and resuspend the cell pellet in fresh medium. This is to remove the presence of DMSO which may cause differentiation of the cells if allowed to remain.
