(b and c) Response curves (b) and AMPK/ACC expression detected by western blot (c) in malignant B and T cells treated with metformin. (d) Metformin inhibited growth of primary lymphoma cells. (e) The proliferation of CD34+ cells enriched from cord blood samples was not altered by metformin up to 120 mM
