NIH loosens stem cell consent rules

Final rules for human embryonic stem (ES) cell research, announced this 
afternoon (July 6) by the National Institutes of Health, require strict 
documentation detailing voluntary donation of embryos leftover from in-vitro 
fertilization procedures, but they also contain a mechanism for approving 
individual cell lines that don't meet the letter of the law but still adhere 
to the spirit of informed consent.

The draft guidelines proposed in April explicitly required certain types of 
informed consent forms showing that cells were first freely donated for 
scientific research generally and then for stem cell research specifically. 
Those rules will apply to all new cell lines created after the rules go into 
effect tomorrow, the final guidelines say, but there's a loophole for 
grandfathering in older cell lines.

After poring over nearly 50,000 comments on its proposals, the NIH decided 
to form a working group to also consider pre-existing ES cell lines that 
don't perfectly match the new protocols but meet certain "core principles of 
voluntary informed consent," Raynard Kington, the NIH's acting director, 
said in a teleconference.

The working group of "around 10 or so" -- which should be up and running 
within one to two months -- will review any and all pre-July 7, 2009, 
US-made lines submitted to it on a case by case basis, as well as any cells 
created abroad that meet ethical criteria "at least equivalent" to US 
standards, Kington said. The group will then make recommendations to the NIH 
director's advisory committee, which will offer final advice regarding which 
cells to fund. All eligible ES cell lines will then be catalogued on a 
central, online master list.

"We agreed that it made sense to have an alternative pathway so that we 
weren't retroactively applying a standard that exists now," said Kington, 
citing an "evolution of the standard of the procedure for informed consent."

Kington said it was "premature" to judge which existing cell lines will be 
approved, including which of the 21 so-called Bush cell lines that were 
eligible under the previous regulations will still be fundable. The rules 
still ban funding for stem cells from embryos created solely for research 
purposes.

"Overall, the administration gets high marks for taking a thoughtful and 
balanced approach," said Massachusetts General Hospital's David Scadden, 
co-director of the Harvard Stem Cell Institute, in an email. He noted that 
the members of the working group have yet to be named, but is confident that 
the NIH will appoint those with "substantive credentials."

Stephen Duncan, a stem cell researcher at the Medical College of Wisconsin 
in Milwaukee, called the guidelines a "reasonable compromise" between 
banning all cell lines that don't meet current best standards and blindly 
funding all previously approved lines.

"I'm really relieved to get here," M. William Lensch, a senior scientist at 
Children's Hospital Boston and the Harvard Medical School, told The 
Scientist. "It's taken a long time to get to today where we have a set of 
guidelines where if you meet these points you can get NIH funding for human 
embryonic stem cell research." Lensch noted, however, that the working board 
deliberations will be time-consuming and somewhat "superfluous" because the 
Institutional Review Boards that manage informed consent processes already 
undergo rigorous NIH oversight. Referring to the many lines created at 
Children's Hospital Boston, Lensch said, "We have confidence that we've done 
this well and they're going to pass muster, but how long is it going to 
take?"

Harvard's George Daley praised the new guidelines as a "major step forward" 
for human ES cell research. "I predict that a treasure trove of lines will 
be made available to the stem cell research community, and that this will 
translate into vital new medical knowledge," he said in a statement. But he 
was disappointed that the NIH did not make funds eligible for cell lines 
made explicitly for research via directed IVF, nuclear cloning, or 
parthenogenesis. "It is my hope that the discussion about the scientific 
merits of all forms of stem cells will continue at NIH, so that decisions 
can be made purely according to scientific merit and not political 
considerations," he said.

Kington said that there has not yet been a sufficient public consultation on 
funding ES cell research from embryos other than those left-over from 
fertility treatments. "We believe that the policy that we put forward now is 
the right policy for where we are scientifically now," he said.
