Aging May Slow When Certain Cells Are Killed

Killing off certain aging cells in the body may lead to a longer life, suggests a new study done in genetically engineered mice. The drug that the researchers administered to the mice only worked because the mice were transgenic, and researchers "can't make transgenic humans," noted Christin Burd, an assistant professor of molecular genetics at The Ohio State University, who was not involved in the new study. In the study, the researchers developed the genetically engineered mice.
