NEW YORK— Scientists in California say they have produced embryos that are clones of two men, a potential step toward developing scientifically valuable stem cells.

The new report documents embryos made with ordinary skin cells. But it’s not the first time human cloned embryos have been made. In 2005, for example, scientists in Britain reported using embryonic stem cells to produce a cloned embryo. It matured enough to produce stem cells, but none were extracted.

Stem cells weren’t produced by the new embryos either, and because of that, experts reacted coolly to the research.

“I found it difficult to determine what was substantially new,” said Doug Melton of the Harvard Stem Cell Institute. He said the “next big advance will be to create a human embryonic stem cell line” from cloned embryos. “This has yet to be achieved.”

Scientists say stem cells from cloned embryos could provide a valuable tool for studying diseases, screening drugs and, perhaps someday, creating transplant material to treat conditions like diabetes and Parkinson’s disease.

But critics raise objections. The process “involves creating human lives in the laboratory solely to destroy them for alleged benefit to others,” said Richard Doerflinger, spokesman for the U.S. Conference of Catholic Bishops. (AP)

And this From Times Online:

Experiments to create Britain’s first embryos that merge human and animal material will begin within months after a Government watchdog today approved two research teams to carry out the controversial work.

The experiments are intended to provide insights into diseases such as Parkinson’s and spinal muscular atrophy by producing stem cells containing genetic defects that contribute to these conditions.

These will be used as cell models for investigating new approaches to treatment and for improving understanding of how embryonic stem cells develop. They will not be used in therapy, and it is illegal to implant them into the womb.

Since when did something being illegal stop the unfettered madman?
