Abstract

There is substantial evidence that many human cancers are driven by a subpopulation of cells that display stem cell properties. These cancer stem cells (CSCs) may also contribute to metastasis and treatment resistance. Furthermore, just as normal stem cells are regulated by their microenvironment or “niche”, CSCs interact with and in turn are regulated by cells in the tumor microenvironment. These interactions involve inflammatory cytokines including IL-1, IL-6 and IL-8, which in turn activate Stat3/NF-κB pathways in both tumor and stromal cells. Activation of these pathways stimulates further cytokine production generating positive feedback loops which in turn drives CSC self-renewal. These cytokine loops and the pathways they regulate resemble those activated during chronic inflammation and wound healing and may contribute to the known link between inflammation and cancer. Inhibitors of these cytokines and their receptors have been developed as anti-inflammatory agents. By blocking signals from the tumor microenvironment, these agents have the potential to target CSCs. Future clinical trials utilizing these compounds will be needed to determine whether targeting the CSC population has clinical benefit.
