Young blood helps repair fractured bones of ageing mice

From the New Scientist:

“Over the past few years, researchers have reversed muscle atrophy, memory loss, heart degradation and some of the effects of cognitive decline by pumping the blood of young mice into old mice. The results from these animal experiments were so intriguing that last year a team at Stanford University began the ultimate rejuvenation trial: giving blood plasma from under 30s to people with Alzheimer’s. Results are expected next year.

Now, Benjamin Alman, a professor of surgery at the Hospital for Sick Children in Toronto, Canada, and his colleagues have tested young blood’s ability to heal bones.”
