In acute myeloid leukemia, a sub-population of quiescent cancer cells, called leukemia stem cells, is thought to be responsible for chemotherapy resistance and eventual recurrence of the disease. Saito et al. show that treatment with granulocyte colony-stimulating factor can overcome resistance to standard therapy by inducing cell cycle entry of the leukemia stem cells.
