NEW YORK (AP) - 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.
