A cell culture model for the treatment of acute myeloblastic leukemia with fludarabine and cytosine arabinoside.
1993
The purpose of this paper was to ascertain whether results obtained in cell cultures of AML clonogenic blast cells would provide a useful model for a clinical regimen that combines fludarabine (F-ara-AMP) and cytosine arabinoside (ara-C). In the cultures the nucleoside F-ara-A was used. Blast cells from the continuous lines OCI/AML-2 and OCI/AML-3 were grown, either in methylcellulose to quantify clonogenic cells, or in suspension to measure self-renewal as reflected in changes in numbers of clongenic cells. F-ara-A, like ara-C, was found to be more toxic to blast stem cells in suspension than in the clonogenic assay, indicating that F-ara-A might, in addition to general cytotoxicity, have soe specific inhibitory effects on self-renewing stem cells
