Asia
A stem cell centre
Singapore and others are racing to grab the lead in a promising
field.

How
do you follow up on Dolly the Sheep?
For
Alan Colman, an English biochemist and a leader of the British
team that created the first cloned mammal in 1997, the answer
was to abandon the cold moors, heaths, and braes of Scotland
for steamy Singapore.
But
it wasn't the tropical weather that drew Colman. Instead,
the 56-year-old scientist chose the city-state because of
its tolerant climate for research using embryonic stem cells.
Not
yet assigned specific roles in the body, these cells are
like blank slates that scientists hope can be used to treat
many different diseases.
But
because the cells are taken from human embryos, funding
for such research has been restricted in the US since 2001.
Singapore,
by contrast, is creating "a centre of excellence in
stem cell research," Colman says, and there's plenty
of funding there, too.
That's
part of Singapore's effort to build a biotech industry.
The government has established a US$600 million fund to
invest in start-ups engaged in research on stem cells and
other cutting-edge life-sciences projects.
Last
year, Singapore opened Biopolis, a 2 million-square-foot
complex of laboratories and offices devoted to such research.
So far,
Singapore has ponied up $22 million for ES Cell International,
the Biopolis-based company where Colman has worked as chief
scientific officer since 2002.
ES today
owns six stem-cell lines (a line is a group of identical
cells that come from the same embryo) and is focusing on
developing treatments for diabetes.
"Here,
there's huge support," says Robert Klupacs, ES Cell's
chief executive officer.
"Astonishing
" progress
Singapore
isn't the only country in the region trying to profit from
the US restrictions. Australia, China, India, Japan, and
South Korea all see stem cell research as a way to get ahead
in biotech.
The
progress the Asians have made is "astonishing,"
says Robert A. Goldstein, chief scientific officer at New
York-based Juvenile Diabetes Research Foundation International,
which has teamed up with Singapore in funding ES Cell's
efforts to find a cure for the disease.
Many
governments have been asking themselves: "Since the
US doesn't seem to be taking a lead role, why don't we?"
observes Goldstein.
What has created this opportunity? President George W. Bush
put drastic restraints on federal funding for embryonic
stem cell research in the US three years ago because many
religious conservatives oppose use of the cells, which often
come from embryos left over after in-vitro fertilisation.
Given
the different religious traditions of Asia, the debate isn't
as heated. "We don't have an ethical roadblock,"
says D. Balasubramanian, chairman of the Indian government's
stem cell task force.
Despite
the progress the Asians have made, many scientists say they
remain years away from developing real therapies using stem
cells.
Nonetheless,
there is anecdotal evidence of early progress.
A Chinese
lab is looking into using stem cells to treat amyotrophic
lateral sclerosis (ALS), or Lou Gehrig's disease.
And
in October researchers at Korea's Chosun University said
they had transplanted stem cells into a 37-year-old woman
suffering from a spinal cord injury, partially restoring
her ability to walk - though there has been no independent
confirmation of this claim.
"We
didn't expect the patient to recover like this," says
Chosun professor Song Chang Hun. "It's almost like
a miracle."
Some
governments have focused on importing talent. China, for
instance, has recruited scientists from top universities
in the US to run research centres on the mainland.
And
in Singapore, 32-year-old Soren Müller Bested, a self-described
"gene jockey" from Denmark, is now the chief technology
officer for Cordlife, a company that focuses on preserving
and researching stem cells found in human umbilical cords.
Bested
and others involved in stem-cell work say the government's
unflagging support gives confidence to scientists worried
about shifting political winds.
"You
won't find out overnight that what you've been working on
for five years has been banned," he says.
Still,
Asian countries are far from assured of leading the way
in stem cells over the long term.
One
big question is whether local universities can produce enough
top-notch researchers, since relying on imported scientists
won't work in the long run.
Another
concern is what some critics see as a lax approach to oversight
and ethics in some labs, including the use of stem cells
drawn from fetuses aborted in the second trimester in China.
More
worrisome for the Asians is the growth in alternative sources
of funding for stem cell research in the US.
While
Bush's reelection ensured that the National Institutes of
Health will not be opening its coffers to US-based researchers
in embryonic stem cells, on Election Day voters in California
approved Proposition 71, which will provide US$300 million
a year to scientists conducting such research in the state.
That
will make it harder for the Asians to attract top scientists.
Seoul,
for instance, has dished out a total of just US$27 million
over the past two years in public money for stem cell research.
Funding
in Singapore and other countries also pales in comparison
to what California plans to spend.
"There's
going to be a very impressive network" in California,
says Randy Schekman, a professor of cell and developmental
biology at the University of California at Berkeley and
an adviser to the Singapore government.
While
he admires the "gung ho attitude" of Singaporean
policymakers, Schekman says Proposition 71's basketload
of money could overwhelm what the Asians can offer.
"We
are going to attract an awful lot of people who will be
eager to move" to the Golden State, says Schekman.
California
may not be the only worry. Britain has a relatively liberal
policy toward stem cell research and may soon kick-start
funding for it.
And
at least five other US states are looking to fund stem cell
research, too.
Even
some of Asia's most prominent boosters concede that the
region will have a tough time matching what the Americans
have to spend. Singapore is building a scientific community,
but currently "it's sub-optimal," says Colman.
"The
people who wrote Prop 71 are trying to recruit people right
now. And when those top people go, so will their teams."
The
Asians insist they're still in the running, and that increased
funding for research - wherever it takes place - will ultimately
help everyone in the field.
"I
don't think any one country can monopolise stem cell research,"
says Susan Lim, chairman of Stem Cell Technologies, a Singapore
startup focusing on ways to extract adult stem cells from
fat tissue.
California's
research effort will attract attention, but "Korea,
Singapore and China will be even more committed to pursuing
it," says Hwang Woo Suk, a researcher at Seoul National
University.
Now
that they have a strong foothold, the Asians aren't about
to give up, even as the climate for stem cell research improves
elsewhere.
