Death Metal suggests we peruse a piece up at Wired on how the Obama administration's draft guidelines for stem cell research could invalidate hundreds of cell lines. "Under the Obama administration's proposed rules for funding embryonic stem cell research, hundreds of existing cell lines could be ineligible, even those that qualified under President Bush. The guidelines were written by the National Institutes of Health and are currently in draft form and expected to be finalized in July. But in their current state, they restrict funding to stem cell lines produced according to new rules that are only now being established. Few existing cell lines will meet those requirements. 'The so-called Presidential lines aren't suitable for actual medical application,' said Patrick Taylor, deputy counsel at Children's Hospital Boston, who criticized the NIH guidelines in a paper published Thursday in Cell Stem Cell. 'But we're talking about many, many more lines. The new lines were created with extensive ethical oversight. They're at stake here.'"
