Summary:
Scientific American reports on a discovery by stem cell researchers at Stanford University that colon tumors contain stem cells may fuel Colorectal Cancer:
"A newly discovered group of cells present in colorectal tumors may be the source of the cancer's ability to grow unchecked. Researchers found that tumor cells containing a combination of three proteins were capable of becoming tumors again when injected into mice. They speculate that the cells may be offshoots of healthy stem cells that no longer respond to the body's natural checks against aggressive, uncontrolled growth."
