Bowing to religious and partisan ideologues in 2001, George W. Bush restricted embryonic stem cell research.

The policy was based on a misunderstanding of embryonic stem cell science, which made it, in Mooney’s words, “a policy based on science fiction.”

"It is intriguing that such mechanistic determinants of embryogenesis could be identified by assembling and interrogating a mouse embryonic stem cell regulatory network, using methodologies originally developed for cancer research," adds Dr. Califano, co-corresponding author on the study.

But rather than allow it to develop into a clone of the patient - the so-called embryonic stem cell could be coaxed into becoming nerve cells which could replace the damaged parts of his brain.

In a 2006 interview with the Tucson Citizen, the retiring congressman called the GOP’s continued opposition to same-sex marriage, abortion and embryonic stem cell research “a terrible mistake.”
