Legislator proposes NIH provide "ethical oversight" for all US stem-cell research

The first Congressional hearing on stem cells in years came together suddenly. Once called, Representative Diana DeGette (a Democrat from Colorado), who’d previously put together twice-vetoed legislation promoting stem cells said she was planning to put forward another version, one that could include a regulatory role for the NIH, even over research it did not fund.

The goal is to lift the federal funding ban on embryonic stem cells created after August 2001 and also set up the National Institutes of Health as a “key player” in a new system for ethical oversight over all cell-based research.

“All this private and state development is being done without ethical oversight,” DeGette’s spokesperson Kristofer Eisenla told me. “A lot of the substance of the bill is still in development, but the overall goal is that all cell-based research would be done under strict ethical guidelines that would be overseen by the NIH.”

How that would play out is still unclear, but it ould be a huge expansion of the Institute’s role. “Historically, the NIH does not have a regulatory role in research, that’s the FDA’s jurisdiction. It could create a very different dynamic [between scientists and the NIH],” said Michael Werner, head of a consultancy specializing in legislative issues affecting biotech. “All stakeholders want to make sure that research is done ethically and appropriately. We need more details of what the Congresswoman is proposing.”

The title of the hearing was “Stem Cell Science: The Foundation for Future Cures.” John Gearhart, a professor of medicine at John Hopkins University, said that he and others testifying before the committee had submitted testimony on that topic and had not known that DeGette would be proposing an oversight role. Otherwise, he said, there could have been discussion on the guidelines drafted by the National Academies of Science and research institutions' use of embryonic stem cell research oversight (ESCRO) committees. "We did not have the opportunity to respond to her, that all institutions are complying with ESCRO guidelines. We’re not just doing what we want."

DeGette’s spokesperson said that the Representative had been trying to bring the stem-cell hearing before the Committee for years, and that the intention was not to bring anything before President Bush but to lay groundwork for future legislation.

See more coverage by the Denver Post.

The hearing was scheduled late last week when another one was cancelled. Coincidentally, it was just two days after the National Institutes of Health had held a long-scheduled meeting on the challenges and promises of cell-based therapies.

Reports from the hearing said that conversation broke down mainly along party lines, with Democrats interested in scientific advances from embryonic stem cell research and Republicans stating that only adult stem cells were so far the only type that had been used in therapy. A report from BioWorld quotes Harvard’s George Daley that adult stem cells have been around for 40 years and embryonic stem cells around for a decade.

Story Landis, head of the NIH Stem Cell Task Force said that if there was any take-home lesson from the symposium, it was that the best source of cells for cell therapies would depend on the disease. For example, neurodegenerative diseases seemed much more likely to be amenable to work from embryonic stem cells, while blood-derived stem cells were effective with some blood disorders.

“It’s clear that adult stem cells are being used in approved trials or early stage clinical trials and other cases where it’s clear that those cells won’t be very helpful.”

Stem cell construction

In a world where space is equated with prestige, California stem-cell researchers are going to be getting a lot more of it. The California Institute of Regenerative Medicine has just awarded $270 million dollars for buildings to institutions all over the state. These funds will be matched by even more than that amount by other donors.

Here is some coverage of this boon to scientific buildings.
The San Diego Tribune consistently does a nice job; this article focuses on the $43 million coming in locally. Another is more general.
The San Francisco Chronicle splashed it over much of its front page and seemed to me to do the best job of covering the impact on California.
The New York Times gave it a mere 600 words, and I couldn’t find it in the LA Times.
And of course, Nature had a full article on CIRM and the national impact on stem-cell science last week. ( See my ramblings and links )

I’d pulled clips on government investment in infrastructure several weeks ago (I thought I’d have time to write in-depth on this but haven’t), and I was surprised to discover that government really doesn’t traditionally invest that much in infrastructure. CIRM is limited to spending 10% of its funds for construction.

I found a lot of skepticism on academic construction in general but haven’t done much reporting. CIRM quotes Paul Berg saying that the hardest problem for people getting into stem cell research is the lack of facilities. Back in February, the head of the Buck told me that if they got the funds to construct a new building for stem cell research, they’d have little trouble filling it with scientists. ( The Buck got $20.5 million to fund the $41 million building.)

Here’s an article from the Economist on whether better facilities for universities are a good idea. (It does not address stem cells particularly, and you’ll need a subscription.) Journalist Dan Greenburg has also written on the unprecedented era of laboratory construction going on. Here’s a recent, statistics filled pdf on college construction.

CIRM and the shape of stem-cell science

Nature has just posted a thoroughly reported feature on how the California Institute of Regenerative Medicine and its billions of dollars will change the shape of stem-cell science and infrastructure. (For a more personal view from a Texas scientist, see our commentary by Peggy Goodell .)

One point the feature makes is that CIRM’s board members also serve the institutions that receive funding from the institute. There are, of course, a welter of rules aimed at avoiding conflicts of interest, but CIRM has still found itself subject to strong criticism. One retired journalist has even started a blog devoted to the institute’s scrutiny. An editorial accompanying the Nature feature calls for strong governance.

Still, CIRM is not the only stem-cell agency facing such charges. A report this week from Integrity in Science reports that “at least 11 of the 25 voting-members of Health and Human Services’ Advisory Council of Blood Stem Cell Transplantation have financial ties to cord blood-banking and transplantation industry despite a committee charter stating that such conflicts should be limited.”

What does seem unique to CIRM are the multiple sources of “two-masters” tension: it must support basic science and clinical applications ( see my interview with Marie Csete) ; it must succor biotech companies but make sure that patients and other scientists can access their technology (see my article on CIRM grants to businesses ). Even its organizational structure is split. (See my article on CIRM’s search for a president .)

I’ve asked CIRM officials about this before. I’m told that such strains are indeed difficult to balance, but done right they are a source of strength. I’ve asked non-CIRM experts about it too. They tell me it’s easy to make bad investments in hot new fields, but good ideas often wither early because they can’t prove their worth. And I've asked everyone whether CIRM’s funds are a good use of money, and they say what journalists hate to hear: time will tell.

Of in vitro meat and cloned drug-sniffers

The entrepreneurial spirit may boost efforts to turn stem cells into fried chicken. It has already expanded the ability to clone dogs. If ideas like these could be tweaked just a bit, they could help spawn research tools the biomedical community really needs.

An idea that might boost cutting edge research (and save animal lives) is coming from a surprising source, People for the Ethical Treatment of Animals. Saying that stem cell science could make in vitro meat possible, PETA has just put up a $1 million prize for the first candidate to make a palatable in vitro chicken product and sell at least 2,000 pounds of it over 10 states.

If PETA had picked pork instead, the research might have had some benefit for the biomedical research community (though it may also have facilitated more experiments using pigs.) No one has worked out a way to get robust pluripotent stem cells in sufficient quantities from species besides mice, monkeys, and men.

Stem-cell skin creams, a San Diego collaboratory, and legal blogs

An article in Tuesday’s LA Times patiently explains that expensive bottles of skin cream sold in doctors’ offices and online do not actually contain stem cells. They don’t have much science either. Other companies are marketing services to store stem cells in menstrual blood. The uterine lining is highly regenerative, but the science is early.

In San Diego, four independent institutions are planning to build a common $115-million facility for stem cell science. Teri Somers covers it well, and some commentators are passionately against. The California Stem Cell Report has comments on this, plus a lively discussion on the meaning of “trivial” in terms of the contribution the California Institute of Regenerative Medicine claimed to have made and actually made to research leading to clinical trials. (The posts are on April 17 and April 15) Back in August, Nature Reports Stem Cells conducted a survey on how recipients of innovation grants intended to use them, noting that the Institute had been kept from disbursing most of the funds it had been awarded)

Mini-research round-up

There’s some cool papers out this week.

Rudolf Jaenisch and Jacob Hanna and others at the Whitehead Institute has not only reprogrammed a fully differentiated cell, but has also generated reprogramming-ready mice. According to everything that’s been published so far, reprogramming specialized cells to an embryonic-like state meant transfecting them with viruses and hoping random chance went your way. Cells in these chimeric mice already contain copies of the transgenes necessary for reprogramming, and these versions of the genes become active when exposed to doxycyclin.

Mike Clarke and Bolaji Akala and others at Stanford use triple mutant mice to help explain a looming question in stem-cell biology is why haematopoietic stem cells (HSCs) self-renew but their progenitors cannot.
