Abstract
A density cut method was used to prepare two subpopulations of bone marrow cells which were enriched (BE) and depleted (BD) respectively of blast cells. Marrow aspirates were obtained from 32 patients, 26 of whom had acute leukaemia. The uptake of a variety of chemotherapeutic agents by these two subpopulations and the acid-soluble ribonucleotide profiles of the populations were compared and significant differences were found in drug uptake by BE and BD subpopulations. For some drugs such as cytosine arabinoside, uptake was greatest by the BE cells, while for 5-azacytidine the BD subpopulation took up the greatest amount of the drug. The preparation of the BE subpopulation also permitted the recognition of several patients with acute leukaemia whose blast cells possess nondetectable levels of ATP, UTP, and GTP components in their acid-soluble fractions. The studies presented demonstrate the necessity of using purified cell populations when characterizing the drug uptake patterns and the soluble ribonucleotide profiles of the leukaemic cells. A simple method for enriching bone marrow aspirates for leukaemic cells is also presented.
