    Journal: Cell Tissue Kinet; 1983 Nov; 16(6):577-82. PubMed ID: 6578875.
    Abstract:
    Previous studies have indicated that the generation time of human leukaemic cells is longer than that of normal haematopoietic cells. We have employed a modification of the thymidine (TdR)-suicide technique to measure directly the generation time of leukaemic progenitor cells capable of colony formation. The results obtained with two human leukaemic cell lines (KG-1 and HL-60) and with blast progenitor cells from two patients with acute myelogenous leukaemia indicate generation times ranging from 9 X 0-22 X 0 hr and S-phase durations ranging from 5 X 5-8 X 0 hr. Using the same technique, the generation time of normal bone marrow CFU-c was determined to be 9-11 hr. These findings suggest that the proliferation rate of human leukaemic blast progenitor cells is similar to that of normal haematopoietic stem cells.
