Rejuvenating aging muscles -- I was really feeling the need for something like that this weekend in the course of my first-ever kayaking trip. I felt my age then . . . NO, correction! I felt my age twice over. But good news-- no after-effects the next day.
Which leads into an article I came upon, "Scientists get closer to rejuvenating aging muscles" by Mary Elizabeth Dallas, in Health Day News (which I had never run across before).
The report is on a study conducted at Stanford's Baxter Laboratory for Stem Cell Biology. The study takes a very different approach than the fictional lab in my technothriller A REMEDY FOR DEATH, but I thought you'd find it of interest.
One thing struck me: "the muscle stem cells in 2-year old mice are the equivalent of those found in 80-year old humans." Implication: maybe there's a market for canes and walkers for old mice!
Seriously, the process involves taking muscle stem cells from the oldsters (only mice, so far) and treat them in a certain way, then reimplanting in those muscle groups. Two months later, those muscles were essentiall equivalent to those of young, uninjured mice.
