Cancer Stem Cells: A New Paradigm for Understanding Tumor Growth and Progression and Drug Resistance
1 May 2009
Abstract excerpt
Normal somatic stem cells (SC) are naturally resistant to chemotherapeutic agents due to their expression of various membrane transporter molecules (such as MDR-1), detoxifying enzymes and DNA repair proteins. In addition, they also have a slow rate of cell turnover and therefore escape from chemotherapeutic agents that target rapidly replicating cells. Cancer stem cells (CSC), being the mutated counterparts of...
