Despite its considerable toxicity to haemopoietic colony-forming cells, 4-hydroperoxycyclophosphamide (4-HC) has successfully been used to purge marrow of leukaemic cells before it is used to rescue patients from high-dose chemoradiotherapy. These conflicting observations indicate that haemopoietic progenitor cells that are not detected by the established colony-forming assays survive exposure to 4-HC and repopulate the marrow. The recent finding that murine spleen colony-forming cells (CFU-S) are resistant to 4-HC [Porcellini A, et al. (1983) Expl Hemat. 11 (suppl 14) 331 (abstract)] [14] also indicates that sensitivity to 4-HC can be used to distinguish primitive progenitor cells from committed progenitor cells. As part of a study on the nature of a population of blast colony-forming cells in human bone marrow, we tested their sensitivity to 4-HC to see whether they also are spared by the drug. We found that 4-HC had much less effect on the blast colony-forming cells than on the granulocyte-macrophage colony-forming cells (GM-CFC). This result suggests that the blast-colony-forming cells may be early human haemopoietic progenitor cells.
