Scientists: Stem cells created from eggs
Thursday, June 28, 2007 07

Scientists say they've created embryonic stem cells by stimulating unfertilized eggs, a significant step toward producing transplant tissue that's genetically matched to women.

The advance suggests that someday, a woman who wants a transplant to treat a condition like diabetes or a spinal cord injury could provide eggs to a lab, which in turn could create tissue that her body wouldn't reject.

Ethicists disagreed on whether the strategy would avoid the long-standing ethical objections to creating embryonic stem cells by other means.

Such cells can develop into virtually any tissue of the body, and scientists hope to harness them for producing specialized tissues like nerve cells or pancreas cells to treat a range of illnesses. But the process of harvesting the stem cells destroys embryos, which many people oppose. the rest
