Now here's a particularly evocative line...

"Some of the rejuvenated cells grew into new mice, demonstrating the cells' ability to create every type of tissue in the body."

From the LA Times, June 7...

Ordinary cells reprogrammed to mirror stem cells

Scientists have succeeded in reprogramming ordinary cells from the tips of mouse tails and rewinding their developmental clocks so they are virtually indistinguishable from embryonic stem cells, according to studies published today.

If the discovery applies to human cells — and researchers are optimistic that it will — it would offer a straightforward method for creating a limitless supply of cell lines tailor-made for patients without ethical strings attached.

The article runs mostly about the uses of stem cells, but I can't help wondering about those new mice... We may be closer to the days of growing new organs for those who need transplants than it appeared. Wonder how close we are to the days of repairing 'em in situ... 20-30 years? Less?

I'm going to wait for the long-term results, though. Remember Dolly? Great initial results, major long-term problems. New organs aren't much help if they go haywire 3-5 years down the road.

True, and you'll note I'm talking about multiple decades here to the desired result. As opposed, to, say, half a century?
