Summary The in vitro treatment of leukemic bone marrows, collected during complete remission, aims at eliminating residual blast cells prior to freezing and preservation, while sparing normal hematopoietic stem cells. We report our experience on the activity of ASTA Z 7557 on human leukemic (CFU-L) and normal hematopoietic stem cells. The sensitivity of human leukemic and normal progenitor cells (CFU-c), detected in semi-solid media cultures, is similar. However, pre-CFUc progenitors detected in long term marrow cultures are much less sensitive to ASTA Z 7557. Therefore autologous bone marrow transplantation can successfully be done with pretreated marrows containing 5±5% residual CFUc. The wide range of stem cells sensitivity to ASTA Z 7557 justify the predetermination of the optimal dose of drug for incubation prior to marrow collection for each individual patient. Our preliminary clinical experience is exposed.
