Surprising new research shows it is possible to rebuild heart-attack-damaged hearts with adult stem cells from bone marrow. Scientists at the National Institutes of Health (NIH) and New York Medical College, Valhalla, NY, demonstrated for the first time that adult stem cells isolated from mouse bone marrow could become functioning heart muscle cells when injected into a damaged mouse heart. More important for future clinical application in humans, the new cells at least partially restore the heart's ability to pump blood.

Scientists at the National Human Genome Research Institute (NHGRI) and the M.D. Anderson Cancer Center at the University of Texas have found a novel tumor suppressor gene on human chromosome 7 that appears to be involved in a wide range of cancers. Tumor suppressor genes play a key role in the regulation of cell growth. Scientists have known for about 15 years that when a tumor suppressor gene is inactivated, the cells it affects grow out of control and become cancerous.
