title: [Sensitivity of the hematopoietic stem cells of anemic animals to actinomycin D].
abstract: It was shown on the model of anemic animals by the method of spleen colonies that non-proliferating CFU-S were resistant against the cytotoxic effect of actinomycin D in concentrations 0.04 to 0.4 micrograms/ml. The entry of CFU-S in proliferation was accompanied by a sharp increase of the sensitivity to the antibiotic in a dose blocking DNA-dependent rRNA synthesis.
