Thinking outside the embryo

Global Politics

When a 2001 federal funding freeze crippled research into the use of embryonic stem cells to treat medical conditions, molecular biologists began searching for alternatives. Now, they may have found one: By reprogramming adult skin cells, researchers have produced stem cells, but in recent studies, the cells produced tumors in mice.
