A new area of cancer research has arisen from the discovery of cancer cells with stem cell-like proper ties in several tumor types including the colon, head and breast. Cancer stem cells, which are undifferentiated cells, have the ability of self-renewal, self-replication and differentiating into malignant daughter cells. Breast tumor s containing breast cancer stem cells have increased resistance to chemo- and r adiotherapy, a higher relapse r ate and increased susceptibility to metastasis. Potential targets for the treatment of chemoresistance include signaling pathways of breast cancer stem cells such as the -catenin-, Notch and Hedgehog pathways. Chemoresistance of these breast cancer stem cells potentially elucidates failure to achieve complete remission post-therapy, and, thus, relapses of breast cancer. By unraveling the mechanism behind the chemotherapeutic resistance of breast cancer stem cells, researchers could develop more efficient treatment strategies towards breast cancer.en© 2016 Biomedical Research PressBreast cancerCancer stem cells (CSCs)ChemoresistanceBiomarkersSignaling pathwaysArticle
