"Stem-cell advance opens up the fieldBy Peter N. Spotts

Colonies of tiny cells flourishing in petri dishes in the US and Japan are reshaping the political and ethical landscape surrounding human stem-cell research.
In the process, these diminutive colonies also may level the playing field in stem-cell research – internationally and domestically.
These are some of the effects analysts say they see coming out of this week's announcements that two teams have genetically reprogrammed skin cells so that they take on the traits of embryonic stem cells.
Embryonic stem cells are the subject of intense medical interest because of their ability to develop into any of the major cell types in the human body. Over the long term, these stem cells could become the foundation for therapies for a range of diseases, scientists say. This week's announcement suggests it will be possible for scientists to study these cells without the ethical and political difficulties of harvesting them from unused human embryos.
For the emerging field of stem-cell research, "this is enormous," says Jesse Reynolds, a policy analyst at the liberal Center for Genetics and Society, based in Oakland, Calif. "I can't think of another development "that has been this big,"
"This is a paradigm shift," agrees Rev. Tad Pacholczyk, director of education at the National Catholic Bioethics Center in Philadelphia. "This will have a huge impact on the ethical debate."
