Metformin Induces Cell Cycle Arrest and Apoptosis in Drug-Resistant Leukemia Cells

Figure 5

Metformin induces cell cycle arrest. CCRF-CEM and 10E1-CEM cells were treated with 4 and 10 mM metformin for 72 h and cell cycle distribution was determined by flow cytometry. Representative histograms showing the distribution of cells on the basis of DNA content.
