Cancer stem cells (CSCs) are believed as the initiators of the occurrence, development and recurrence of malignant tumors. Targeting this unique cell population would provide a less toxic approach than regular chemotherapeutic agents that kill bulk rapid proliferating tumor cells and also normal cells which divide rapidly. To date, major research effort has been aimed at identifying and eradicating CSC population. The metabolism heterogeneity of mitochondria in CSCs shows a big promise for cancer research. Of them, mitochondrial membrane potential (Delta psi m), reflecting the functional status of the mitochondrion is proved to be highly related to cancer malignancy. Reactive oxygen species, mainly produced from mitochondria, are also increased in many types of cancer cells. However, their statuses in CSCs remain poorly understood. Here we shall review the mitochondrial membrane potential and reactive oxygen species of CSCs and propose the novel potential targets for cancer therapy.
