Old Stems Cells Young Again... with Vampirism?

pdragon04 (801577) writes "In virtually every part of the body, stem cells stand ready to replenish mature cells lost to wounds, disease, and everyday wear and tear. But like other cells, stem cells eventually lose their normal functions as they age, leaving the body less able to repair itself.

Surprisingly, this age-related decline in stem cell potency may be somewhat reversible. A team of Howard Hughes Medical Institute (HHMI) researchers has found that in old mice, a several-week exposure to the blood of young mice causes their bone marrow stem cells to act “young” again."
