This author is wrong in his premise if he thinks this will "re-ignite" the embryonic stem cell debate. To the contrary, it should be one more nail in its coffin.
Those who oppose embryonic stem cell use support the use of stem cells from umbilical cords and placenta, as well as adult stem cells. That's the point -there are nondestructive alternatives that actually show more promise than embryonic stem cells.
This isn't about debate. These scientists are working on possible cures. Their work has and will continue with or without the political, religious and social bickering.
