In 2004, with President George W. Bush dead set against stem cell research, California just went ahead and did it. Voters made stem cell research a state constitutional right, and endorsed $3 billion in bond sales for 10 years to cement the deal. CIRM, the California Institute for Regenerative Medicine created under Proposition 71, has become a world center for stem cell research, and its president is Australian Alan Trounson, a pioneer in in vitro fertilization. As Proposition 71 approaches its 10-year anniversary, Trounson offers a prognosis.


Q: It's been almost 10 years since California funded what may be the world's biggest stem cell research program. What are you up to?

A: We are working hard to get six or seven projects to clinical trials. We have more than 70 (total) programs moving (toward) clinical trials. It's a lot of work to chaperon.

I'll give you three examples: one, linking genetics, or genomics work, to stem cells, integrating the two. We're going to create a center in California that will bring a lot of (genetics) studies and clinical work to a new level.

Secondly, we've set up a structure for banking the 3,000 cell lines from "induced pluripotent stem cells" that we turn into the equivalent of embryonic stem cells. We call them IPS cells. You take a skin cell or blood cell and convert it to the equivalent of an embryonic stem cell.

We've also taken samples from patients with complex diseases, and we're banking these so scientists can "interrogate" these diseases — like heart disease, Alzheimer's, blindness. We are targeting a range of conditions — autism, cerebral palsy — for which we have scant understanding of causes and major drivers. This is material for long-term research studies.

What we're doing is meaningful. Somebody with cancer may have a better treatment. Parkinson's patients might be in a clinical trial around 2016, 2017.

Q: Are Californians getting enough bang for their buck?

A: I think we're way ahead of what people predicted. Nevertheless, it takes a lot of time to do this. I think we're hurrying carefully.

Q: What else?

A: I'm intending to set up a network of stem cell clinics in California in the next couple of years, to make treatments available as clinical trials or as registered treatments for patients. I'm going to ask the (CIRM) board for about $70 million to get that set up. It will make California a go-to place for stem cell therapies. I want to make sure it's part of our medical fabric.

Q: An Oregon scientist reports that he has cloned human stem cell lines. Is Oregon doing something different from California?

A: The one thing that's different is that we can't compensate women adequately for donating eggs (as a source for creating a particular type of stem cell). We can pay for the cost of drugs but not for the time and inconvenience. So that really does limit the number of women who would like to donate eggs to research, and that's a handicap. I think it would be very useful to develop those cell lines.

Q: The words "cloning" and "human" together set off alarm bells for some people.

A: (Under Proposition 71) we can't do any reproductive cloning. We can't do it and we shouldn't do it — none of us wants to do that — but we would like to make those cell lines.

Q: Is stem cell research highly competitive now, as it was in the 1980s, when you were beginning your work?

A: I don't think it's very competitive at all. There's a little bit of competition between California and Harvard, but that will always be the case, I suspect. What's important with (California's) $3 billion is that it's taken away a lot of the silliness of the competition — that you hold your data and you don't show anyone and you wait until you (get it published) in a journal. In Australia, there's very few funds for this kind of work and so it's extremely competitive — you don't know what others are doing even in the same laboratory. That's not the case in California. People are collaborating, and that's why we're moving so fast because we work together. Scientists like to reach out to other scientists.
