Has Tightened Genetics Regulation - Rules Ban Human Cloning;
Moves
Could Quiet Critics Of Freewheeling Research

SHANGHAI - China's days of freewheeling research into
reproductive medicine and cutting-edge genetics could be numbered.
After
years of indecision and half-hearted attempts at regulation,
Beijing has quietly implemented a sweeping new directive aimed
at regulating research into the human reproductive system
and the role that genetic science plays in it, according to
officials at the Ministry of Health. The new rules took effect
Oct. 1 but were only announced on the Ministry of Health's
Web site on Friday.
Among
the most strident points of the new regulations are a blanket
ban on human cloning and new controls on genetic experimentation
on human eggs and sperm for fertility purposes. It also outlaws
for-profit trading in human eggs and sperm -- a move that
is likely to restrict access to the raw materials that scientists
need to conduct research and practice fertility medicine.
"It's
a very strict set of regulations," said one genetic scientist
in Shanghai. "The biggest impact is that government [hospitals]
will no longer fund research that is deemed sensitive."
The
new rules, if enforced, could help quiet foreign critics who
have faulted China in recent years for permitting a range
of controversial genetic research. It is likely to be viewed
positively by ethicists and conservative politicians in other
nations, including the US.
Though
still a relatively young field, genetic science has made vast
strides in recent decades, particularly in the realm of human
reproduction. Genetic discoveries have helped reduce the risk
of congenital birth defects and other disorders, such as Down
Syndrome. New research in promising fields such as embryonic
stem cells - a sort of master cell that can develop into a
wide range of human tissues - has raised the possibility of
cures for many other illnesses, as well as for potentially
commercial benefits.
Yet
along with progress has come controversy, nowhere more than
in the science of human reproduction. Some aspects of embryonic
stem-cell research, for instance, have relied on techniques
that could also be used to clone a human being. Just to obtain
embryonic stem cells, scientists often have to create - and
destroy - human embryos.
All
that has raised important ethical concerns and questions about
how the industry should be regulated.
Until
now, Beijing appeared largely unmoved by such concerns, showing
more interest in supporting domestic efforts to unlock the
secrets of genetic science. From the human reproductive system
to the genetic structure of cucumbers, rice and cotton, government
funds have flowed freely to the industry in recent years,
reflecting Beijing's view that the science holds vast economic
benefits and could eventually propel China to scientific greatness.
Indeed,
in some fields recent progress has been so great that Chinese
scientists have already caught up with counterparts in the
US and other developed countries. In Guangzhou, one scientist
reports he has created more than 100 hybrid embryos by combining
DNA from human skin cells with rabbit eggs. In central Hunan
province, a team of scientists are using a technique similar
to one that could be used to clone a human being, but for
the purpose of harvesting embryonic stem cells for research.
In recent years, nearly 500 fertility clinics have sprouted
up across China, more than a
third of them specializing in in vitro fertilization.
Now,
Beijing appears to have adjusted its position. Some Chinese
researchers said the decision to issue industry guidelines
reflects Beijing's concern that China was becoming a magnet
for foreign scientists, some of whom had begun moving research
to China as a way to get around restrictions in their own
countries. That raised the possibility that scientists could
veer into sensitive ethical areas without the government's
knowledge.
That
now appears far less likely. The new rules, at least on paper,
leave China with a regulatory framework for genetic science
that could potentially be more restrictive than those in the
U.S. and the United Kingdom, both of which are also laboring
to keep pace with such technology.
China's
rules still differ in many ways from those in the U.S. Beijing,
for instance, didn't address the issue of research funding,
leaving the industry open to both foreign and domestic capital,
including government funding.
Beijing
also left vast stretches of the industry wide open, such as
stem-cell research, as long as human cloning isn't involved
and scientists don't apply their findings on a commercial
basis. That, experts say, suggests genetic research in China
is likely to continue to thrive.
Even
so, Chinese genetic researchers and scientists say the rules,
if aggressively implemented, are likely to have a chilling
effect on research and the human-fertility industry that until
now has been growing by leaps and bounds amid a near complete
absence of regulation. At a minimum, these researchers say,
they are likely to give Beijing far greater say over what
type of genetic research is undertaken in China.
"This
is good for the long-term development of this scientific field,"
said Chen Xigu, a scientist in Guangzhou. "Otherwise,
it's possible there could be a disaster before we figured
out how this science can benefit mankind."
The
big question now is how aggressively Beijing implements the
new rules. As in other parts of China's economy and society,
Beijing's previous attempts to regulate reproductive science
and human genetics have been largely ineffective. Just over
two years ago, for instance, China's Ministry of Health announced
an official ban on all commercial trading in human eggs and
sperm.
Yet
that rule has been widely ignored, with dozens of fertility
clinics and even some hospitals collecting, storing and selling
sperm and eggs without government approvals or licenses. Even
many well-established fertility clinics that don't trade in
eggs or sperm operate without formal approval.
One
of them is the Guangdong Jiai Genetics & IVF Institute
China-USA Center. Backed by technical support from a U.S.-based
fertility clinic in Fairfax, Virginia, Jiai Genetics has been
operating for about three years without a formal license issued
by the Ministry of Health, said Wu Jingzhi, the clinic's director
of operations.
But
Dr Wu shrugged that off. Jiai Genetics, she said, is in the
process of applying for a central-government license, and
local officials have continued to allow the clinic to operate
while the license is under review.
"It's
not a problem," she said.
Questions
over how Beijing implements the regulations are likely to
linger. Some of the rules, such as the ban on human cloning,
are straightforward and unlikely to be challenged. But other
aspects, such as a ban on altering the genetic structure of
eggs and sperm and then applying those changes during individual
fertility procedures, are less clear and potentially open
to interpretation, experts said.
Yet
for many Chinese scientists, Beijing's message is already
clear. "The core issue," says the prominent Shanghai
scientist, "is to prevent human cloning . . . China naturally
doesn't want to become a legal loophole for the world."
