Experimental study on bone marrow CFUs following anticancer drug administration to plethoric mice.
The effect of some cycle-dependent anticancer drugs on CFUs has been studied in transfused polycythemic mice. In untreated animals during passive plethora erythropoiesis is depressed but the content of CFUs per femur remains constant. In treated plethoric mice the femural content of CFUs is similar or higher than that found in treated controls after administration of adriamycin, vinblastine, cyclophosphamide, it is lower when the mice receive azathioprine or hydroxyurea. These results suggest that suppression of erythropoiesis does not uniformly affect the susceptibility of pluripotent stem cells to anticancer drugs. Interpretation of the reported findings is difficult as it must take into account a complex interplay of a number of factors.
