A new inhibitor suppresses tumor growth and cancer stem cells. The image on the left shows beta catenin (red) in cell nuclei indicating that these are cancer stem cells. All tumor cells are the offspring of a single, aberrant cell, but they are not all alike. Only a few retain the capacity of the original cell to create an entire tumor. Such cancer stem cells can migrate to other tissues and become fatal metastases. To fully cure a patient’s cancer, it is crucial to find and eliminate all of these cells because any that escape can regenerate the tumor and trigger its spread through the body.
