pubmed:abstractText |
The mouse hematopoietic stem-cell population was tested by the spleen colony technique for effects of the antineoplastic agent bleomycin (BLM). The time response of normal bone marrow was investigated by a single dose of BLM (400 mg/kg) between 0 and 72 hours. The dose response was studied over a wide range of doses (from 40 to 1,600 mg/kg) at a 4-hour exposure. Additional experiments concerned 1) the fraction of colony-forming units in the S phase after BLM administration (by means of pulse hydroxyurea treatment), 2) the response of bone marrow stimulated by endotoxin, and 3) the effects of split-dose treatments. The relatively low toxicity of BLM on both the differentiated and stem-cell populations of unstimulated bone marrow was confirmed and detailed. This drug exhibited peculiar, proliferation-dependent cell inactivation kinetics. Furthermore, BLM induced parasynchronous behavior in the unstimulated stem-cell population. The various aspects of BLM action are discussed with regard to its use in cancer chemotherapy.
