These experiments suggest that the majority of both normal and CML CD34+G0 and G1/S/G2/M cells remain viable and can be stimulated to proliferate with 7 cytokines, but that the CML/G0 cells are more poised than the normal G0 cells to begin proliferating. The gene discussed is CD34; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
