Reviving Brain Cells From Corpses 11
dachshund writes: "ABCNews.com has an article on some scientists who have managed to bring a corpse's brain cells back to life in a Petri dish. Yikes. Doesn't seem to be a Frankenstien scenario, though-- the main applications have to do with stem cell research. Sort of makes you think, though..."

Bad me. "their" should be "they're". I never made this mistake when I was a little kid. I must be losing my neurons too fast. Usually I preview obsessive-compulsively before I post too.

Stem cells of various types exist in many places in your (living) body; in principle, there's no reason they have to be harvested from anywhere else at all.
In practice, embryo cells are nice because they haven't differentiated at *all* yet (stem cells in your body have differentiated a bit, and so only give rise to certain types of cell (e.g. blood cells for bone marrow stem cells).
Research is ongoing to try to convert these back into general-purpose stem cells. There has been some progress, some of which has been covered on slashdot.
In summary, we won't have to worry about harvesting by the time we're ready to use stem cells on a large scale.
For pure research into differentiation, there's no reason we'd have to use human stem cells. If I understand correctly, human stem cells are only used for research into medical procedures that are intended to be performed on humans, which could be delayed until the differentiation problem is solved or performed on animals instead (though both options mean it'll be longer until the techniques are perfected for use in humans).

I believe we really need to find a good supply of stem cells somewhere in the body which we can use to treat diseases like Alzheimer's. It seems to be the most promising solution proposed yet.
Hopefully cells from cadavers works well enough to make this a reality.
