Abstract

In the present study we utilized a semisolid culture system with feeder cells and enriched media to evaluate the growth of acute leukemia associated with the 4;11 chromosomal translocation. We compared growth of t(4;11) leukemia to typical acute nonlymphocytic leukemia (ANL) and acute lymphocytic leukemia (ALL). The two cases of t(4;11) leukemia tested exhibited the highest cloning efficiency of cells tested. The growth characteristics of t(4;11) leukemia were more similar to ANL than ALL.
