More Good Stem Cell News

Researchers
have found a potential new source of embryonic stems cells, eggs that have been
coaxed into
dividing
as though fertilized:

A trick that persuades human eggs to divide as if they have been fertilised
could provide a source of embryonic stem cells that sidesteps ethical objections
to existing techniques. It could also be deployed to improve the success rate
of IVF.

The tricked eggs divide for four or five days until they reach 50 to 100
cells – the blastocyst stage. These blastocysts should in theory yield
stem cells, but because they are parthenogenetic – produced from the
egg only – they cannot be viewed as a potential human life, says Karl
Swann of the University of Wales College of Medicine in Cardiff, UK.

“This could eliminate one of the main sources of ethical controversy
in this research,” says Bob Lanza, head of research at the cloning company
Advanced Cell Technology in Worcester, Massachusetts.

This follows close on the heels of news
from Korea that researchers have used stem cells derived from umbilical cord
blood to enable a woman paralyzed from the waist down to walk. I have argued
for some time now that the best way forward in the stem-cell debate is to find
a win-win situation, something that provides the benefits but avoids the ethical
snares. We appear to be getting closer to such a solution (or to a set of such
solutions.)

Stillness Part VI, Chapter 54

Ksenia awoke with a start, frightened and confused. She always awoke this way, ever since that terrible night years before. There had been only one exception, one night of undisturbed rest, and it had occurred early on. But that was now more than five years in the past. It had been that long since she had awakened in the arms of Reuben Stone, only to say goodbye to him later that day. Five years of waking up terrified, convinced that she was still in that room, facing down the monsters with their guns, watching her brother die.

One night in all those years.

Even those nights some years earlier when Ivor’s crying had awakened her, her dreaming mind had confused the sound with Pasha’s screaming in his final moments. It had been such a wonderful relief to come fully awake and realize that the crying was her son. That whatever was distressing him, Ksenia could make it right.

But Ivor was bigger now; he had been sleeping through the night for years.

Ksenia’s heart was racing. There was someone there in the room with her. All she had to do was roll over and there he would be. She had often dreamed that this would happen, and that it would be Reuben standing at the foot of the bed. But that dream always dissolved in horror. The man would be Reuben while her eyes were closed. But when she opened them, it would be the man with the gun, or the man who commanded the game. They had come for her. What Reuben had accomplished that night was not a rescue, only a reprieve. Her life was theirs for the taking; it had always been so. And now they had come to claim that which was theirs.
