Subject: Cryonics advances since 2000?
Date: Mon, 10 Dec 2007 14:35:47 -0800

I'm corresponding with a cryonics naysayer who says
he won't be sold till we can re-animate a mammal.  In
looking for responses, I ran across this article by a
non-cryonics person talking about what can be done so far:
http://www.research.uky.edu/odyssey/fall00/freezing.html .
If you believe life begins at conception, we've already
revived a mammal, since human embryos are routinely
frozen and implanted.  It's when they've differentiated
that it gets tricky; the MNT and AI will be needed to
direct the appropriate levels of cryoprotectants to the
various body tissues when needed and to remove them at
the proper times (assuming we don't come up with some
more clever method before then).

That article was written in 2000.  Have we made no
advances in revival since then?  Would incremental
advances be valuable -- for example, cryopreserving then
reviving/implanting an embryo (mouse or rabbit, so as not
to cause a giant furor) that had undergone more cell
divisions?  I'm under the impression that embryos have
only been preserved up to the 8-cell stage.  My brief
Web search shows that they are at "several hundred"
cells by the time they implant.  That's about five
divisions down the line.  What's the problem with 16 or
32 cells or more?  Thanks in advance for comments.

Live long and prosper,
Kennita
