Researchers build colony of colon cancer stem cells to test new approach to therapy

Researchers have devised a three-dimensional system in laboratory culture that mimics the growth patterns of colon cancer stem cells in patients. The assay, which uses green fluorescent "reporter" proteins to watch the process of stem cell differentiation, is designed to understand how these cancer stem cells behave, and to identify and test therapies that could halt production of the endless generations of new cancer stem cells that continually revive a tumor.
