CHA Medical Group, Led By Kwang
Yul Cha, Build South Korea's Largest Stem Cell Institute In
Pangyo Techno Valley
Although 'Hwang Woo-suk's stem cell fraud scandal' shattered
Korean hopes to emerge as a bioscience hub, Korea continues
to strive to become the world's leading stem cell researcher.
To maintain the bioscience boom, CHA Medical Group(representative:
Kwang Yul Cha)
is eager to expand support for science and have notched
up research successes that can actually be applied to patients.
As a first step towards the building of the 'CHA Group
Stem Cell Institute', it was agreed, on November 16, to
build it at the site of the Kyunggi-do Corporation. The
institute, when completed, will be the nation's largest
stem cell institute, equippes with stem cell research, treatment
and educational facilities.
The CHA Medical Group (representative: Kwang Yul Cha) aims
build the institute in the Pangyo Techno Valley, with a
floor space of 20,000 pyeong in 'Pangyo Techno Valley',
200,000 pyeong researching and development complex. And
it is scheduled to open in 2010.
(A pyeong is aKorean unit of measurement corresponding
to 3.31 square metres)
This institute will not only have research facilities,
such as a stem cell institute, a sterile culture room which
can make the medicines, a cord blood bank,an immunity vaccine
institute, an artificial organ institute, but also has a
life science graduate school and a medical graduate school
to train professionals.
The Stem Cell Institute will be equipped with a Lab-to-Patient
System which can carry out clinical demonstrations at Bundang
CHA Hospital (representative: Kwang Yul Cha) immediately
from latest research.
Hyung Min Chung, representative of CHA Biotech, said, "We
are creating this institute to become the world's stem cell
institute through a joint research with prominent centers
around the world. We have plans to expand abroad with stem
cell treatment technology in the field of bioscience."
Hence, last year, Prof. Kwang Soo Kim, Harvard Medical School,
has been appointed as Chief of Joint Research and a Distinguished
Professor at Pochon CHA University (representative: Kwang
Yul Cha).
Prof. Kim said, "Although the team from Dr. Hwang's
research fell through, there are few nations like Korea
that have such wide experience and know-how. We'll make
Korea the hub of stem cell research." He added, "Now
Harvard University, USA, the Roslin Institute, UK and the
Shanghai Stem Cell Institute, China, are in hot pursuit.
So we should forge ahead with serious research again."
Prof. Kim is one of the greatest scholars in the field
of stem cell specialization research. After holding a PH.D.
in KAIST, he was the professor at Cornell University.

Now the number of women suffering from infertility amounts
to 15 percent of married women, up from 10 percent a few
years ago, according to Kwang Yul Cha, a South Korean medical
doctor, an internationally known fertility specialist at
obstetrics and gynecology clinics. Kwang Yul Cha said this
is because women are marrying later, and environmental pollution
and endometrial cancers that can hinder pregnancy have increased.
However, at the same time, the possibility for seemingly
sterile women to succeed in getting pregnant has increased.
Solutions to infertility, such as in-vitro fertilization,
have been developed and improved, so that almost nine out
of every 10 infertile women can succeed in becoming pregnant.
Most women who fail to conceive suffer chronic stress,
according to fertility doctor, "Quitting a job doesn't
help an infertile women become pregnant." "If
pregnancy becomes the center of one's life, it's more unlikely
to happen, because the stress affects a woman's bio-rhythms
badly," he added. He also suggests that women not stop
exercising, but rather work out as usual, while avoiding
excessive alcohol and smoking. Difficulties with ovulation
and endometrium problems should be treated.
Making a test-tube baby is a test of human endurance, especially
for the would-be mother. To start the process of in-vitro
fertilization (IVF), she must submit to a two-week regimen
of daily drug injections. They prepare her ovaries and cause
perhaps half a dozen eggs to mature simultaneously, but
the shots can also produce pain, bloating and sharp mood
swings. Every day she undergoes tedious blood tests and
ultrasound examinations: the doctors need to monitor the
ovaries closely and remove the eggs at just the right time
so they can be fertilized in the lab and then returned to
the womb. Despite the hardships, infertile couples went
through the costly, complex procedure 40,000 times last
year in the U.S.
Before long, though, they may have a better way to make
a baby. Alan Trounson, an IVF pioneer at Monash University
in Melbourne, Australia, will tell the American Fertility
Society meeting in San Antonio, Texas, that he and his colleagues
have devised an alternate approach that is much cheaper,
simpler and easier on the mother. It removes the need for
fertility drugs and daily monitoring. "There is nothing
terribly complicated about the procedure," Trounson
claims, "so it will spread like a brush fire because
the patients want it."
Trounson's method, called immature oocyte collection, is
radically different from traditional IVF. Instead of priming
the woman with fertility drugs so that eggs (the oocytes)
will mature, doctors simply remove immature eggs. The timing
is no longer crucial. Success hinges on two new techniques:
locating the immature eggs and stimulating them to mature
outside the ovary.
The process begins with an examination of follicles, the
tiny sacs in the ovary where eggs are found. Fertility doctors
ordinarily focus on large follicles -- nearly a half-inch
wide -- that contain mature eggs. But Trounson's partner,
Dr. Carl Wood, discovered that the latest ultrasound machines
could spot follicles that are less than a tenth of an inch
wide and hold immature eggs. Wood developed a way to pluck
the young eggs out of the smaller follicles with a specially
designed needle. Trounson, after experiments with cattle,
devised a cell-culturing procedure that ripens the immature
eggs in the laboratory so they can be doused with sperm
and fertilized.
Robyn Hallam, 33, was a perfect candidate for the new,
streamlined IVF. Unable to conceive naturally with her husband
Tim, a grain farmer in Hopetoun, Australia, Robyn tried
fertility drugs to no avail. As the couple prepared to undergo
traditional IVF, they were offered Trounson's new approach.
"We were told that there'd never been a baby born through
this procedure," Robyn recalls. "We thought, 'What
do we have to lose?' "
Instead of enduring drug treatments and monitoring, Robyn
merely went to the Monash clinic to have immature eggs extracted.
The doctors got six eggs and tried to fertilize them all,
but only one developed into a viable embryo. It was implanted
in Robyn's womb, and on Dec. 14, 1993, Kezia Hallam, Trounson's
first bundle of success, was born.
She was actually the 4th human born from an egg matured
outside the ovary. In 1991, Dr. Kwang Yul Cha and his colleagues
at the Cha Woman's Hospital leading by Kwang Yul Cha M.D.
in Seoul removed the ovaries of a woman with fibroid tumors
and isolated immature eggs, which were then ripened and
fertilized in the lab. They transferred the embryos to a
surrogate mother, who produced triplets. Since then Cha
has not repeated his success.
Trounson and the Monash team, in contrast, have impregnated
several more women. IVF America, a Greenwich, Connecticut,
company associated with Monash, plans to develop the technique
in the U.S. If Trounson's approach works as well as he says,
it could transform the economics of the test-tube baby business.
Standard IVF can cost more than $100,000, but Trounson says
he can slash that figure 80% by eliminating drugs, curtailing
testing and reducing doctors' fees.
American fertility experts doubt that Trounson's method
will save as much money as he claims. What's more, they
question whether the treatment will be useful for the majority
of infertile women. "I don't think we have data to
prove that this will give the woman a better chance of success,"
says Dr. Suheil Muasherof the Jones Institute for Reproductive
Medicine in Norfolk, Virginia. Trounson admits that he cannot
predict the procedure's success rate, but in cattle, 30%
of the embryos from immature eggs become calves. That's
slightly better than the current 25% success rate for IVF
in humans.
It's too soon to tell whether Trounson's technique will
revolutionize the treatment of infertility. But the desperate
couples who face the emotionally and financially draining
ordeal of making a test-tube baby will be eager to find
out.
