Friends,
There was a story on the ABC "World News Tonight with Peter Jennings"
last night (22 Feb.) about the possibility of immortality. A bit
farfetched, but they had an interesting interview with one Michael
West, who is experimenting with techniques for turning adult cells
into embryonic stem cells. From what was said the technique is much
like cloning, except that the cloned egg is not allowed to grow
beyond an early stage.
The obvious advantage to this is, of course, that the stem cells thus
produced would be *your* stem cells -- no rejection.
While the story was talking about organ replacements leading to
immortality, once you have stem cells in hand you might be able to do
something about PD.
Here's the URL of an article on the ABCNews.com web site about this.
I've included what I consider the most relevant quote for those who
don't wish to look up the entire story. Watch out for the URL being
word wrapped by the e-mail programs - it's a long one.

> There are already promising results in animals.
And here is the transcript of the TV story, again with the most
relevant quotes:

Has anyone else heard of this particular line of research?
Best,
Bill
