Using New Approach, Scientists Find Evidence for Cancer Stem Cells

(Courtesy of University of Michigan Comprehensive Cancer Center) With the help of genetic tools, researchers have identified subsets of cells that appear to drive the growth of tumors in mice. The findings, from three independent studies, provide new support for the cancer stem cell hypothesis—the idea that some tumors are sustained by self-renewing cells that give rise to all types of tumor cells. Two of the studies appeared August 1 in Nature, and the third was published on the same day in Science.

The NCI Cancer Bulletin is produced by the National Cancer Institute (NCI), which was established in 1937. Through basic, clinical, and population-based biomedical research and training, NCI conducts and supports research that will lead to a future in which we can identify the environmental and genetic causes of cancer, prevent cancer before it starts, identify cancers that do develop at the earliest stage, eliminate cancers through innovative treatment interventions, and biologically control those cancers that we cannot eliminate so they become manageable, chronic diseases.
