WASHINGTON, D.C. --According to at least one legend, 1000-year-old vampires assure themselves long, healthy lives by drinking the blood of young victims. Similarly, old mice that share the blood of young mice repair injuries with youthful prowess, according to research presented here 8 December 2004 at the American Society for Cell Biology Annual Meeting. The results suggest that youthful rodents pump a compound into the blood that keeps tissue-replenishing cells active.
