Stem Cells Help Attack Cancer In Mice

Stem cells, immature cells already showing promise as tools to regenerate and replace damaged tissue, may also help target and destroy cancer, U.S. scientists said on Monday. Tests in mice showed the cells could deliver powerful cancer-killing proteins, destroying tumors while leaving healthy cells untouched. Dr. Michael Andreeff and colleagues at the University of Texas M. D. Anderson Cancer Center in Houston used cells taken from bone marrow. These immature cells, known as mesenchymal stem cells, usually give rise to muscle and other tissues.
