Bush's decision has been denounced as 'morally unacceptable' by the leadership of the Roman Catholic Church in the U.S.
Others, such as Canadian-born actor Michael J. Fox, welcomed the move to allow limited research. Fox is an advocate for research into Parkinson's disease, from which he suffers.

Frozen stem cells |
Canadian scientists have been world leaders in cell research since the 1970s. They've done much work into mouse and adult stem cells.
When it comes to embryonic cells, however, they're waiting for new regulations to come into place.
Ottawa has prepared draft legislation that would control what scientists can do. It's similar to the proposal announced by Bush, allowing research on existing cell lines from embryos that have already been destroyed.
But the Canadian regulations would go one step further. They would allow scientists to conduct studies on newly-generated cells as well.
Those draft rules are supported by many leading cell researchers, including Dr. Janet Rossant of Mount Sinai Hospital in Toronto.
"It brings a clearly regulated environment for researchers to work with these cells. It allows a wide range of researchers to explore their potential. And since these cells have the potential to make so many different cell types, there really is the hope that they can be used in the future to help repair damaged tissue," she said.
Rossant says that could lead to new replacement organs being grown, even cures for many diseases.
But for some, the research goes too far.
Dr. John Shea is with Campaign Life Coalition. He says it's wrong to allow scientists to harvest embryos which he considers to be living organisms.
"If we decide that there are certain classes of human beings which can be used like a product for some other good reason even, then we send a sign: we've gone right back to Nuremberg. People's rights don't come from the government."
The regulations concerning cell research in Canada will be determined by the House of Commons. Right now, the draft legislation is being considered by a parliamentary committee.
Tim Caulfield, a professor with the Health Law Institute at the University of Alberta, says there's no doubt those proceedings will be controversial.
"It's very difficult for regulators to compromise and to come up with a policy to make everyone happy. So no matter what happens in Canada, not everyone is going to be happy, and this controversy isn't going away."
Many expect it will only heat up as Parliament considers the legislation.
The federal Health Department expects the bill could become law by the spring of next year.

Pope Alleged Allowing Stem Cells to be taken from cords of babies. Did he understand the weakening of the babies?
Pope to Bush - don't allow stem cell research
Last Updated Mon Jul 23 16:34:15 2001
CASTEL GANDOLFO - U.S. President George W. Bush said he would consider Pope John Paul II's appeal when he makes his final decision on whether to allow medical research using human embryos.
Following the first meeting between the president and the pontiff, John Paul said America has a moral
responsibility not to allow
stem cell research, or any other actions that "devalue" human life.
Pope John Paul II and President George W. Bush
Bush said he wasn't surprised by the Pope's admonition, but said he needs to balance concerns about
respect for human life
with the promise scientific research holds.
Bush and the Pope met behind closed doors at the papal summer residence at Castel Gandolfo south of
Rome.
Speaking later, Bush said the subject of stem cell research didn't come up in his talks with John Paul.
Rather, the Pope wanted to
focus on foreign policy and Bush's meeting on Sunday with Russia's Vladimir Putin.
Bush and the Russian president discussed the future of arms control in light of U.S. plans for a missile
defence system.
A Vatican spokesman said the Pope opposes any stem cell research that uses embryos. Other sources of
stem cells such as
umbilical cord blood were not condemned by the Pope.
On one side, scientists say stem cell research could lead to cures for Alzheimer's disease, Parkinson's,
diabetes and spinal cord
injuries.
But anti-abortion activists oppose the research saying harvesting stem cells kills an embryo, which
they regard as human life.

Canadian Institute of Research:
Canadian research furthers stem cell growth
Last Updated Wed Jan 31 10:33:30 2001
LONDON, ONTARIO - Stem cell research is often controversial - a minefield of ethical concerns surrounds its use of aborted fetuses and human embryos. New research may change all that - allowing researchers to grow adult stem cells in a lab.
Researchers at the J.P. Robarts Research Institute in London, Ontario, take credit as the first to accomplish
that feat. Dr. Mickie
Bhatia and his colleagues took a protein known to make embryonic stem cells reproduce, and used it on
adult stem cells.
Dr. Bhatia
Adults have small numbers of stem cells in their bone marrow or other parts of the body, but the cells appear to be in a slow-growth mode, not reproducing as they did in the embryonic stage.
But once given the protein, they started to grow and reproduce.
The protein in question has the different name of 'sonic hedgehog,' the legacy of the video-game-loving
scientist who discovered
it.
Other effects
Apart from easing ethical concerns, the discovery may make life easier for cancer patients.
Before undergoing chemotherapy, patients often have bone marrow cells removed by their doctors. The
cells are cultured, to be
reinjected after the chemo treatment.
By adding the sonic hedgehog protein to bone marrow cultures, marrow cells may grow more quickly, giving
a bigger boost to
patients' recovery.
The work will be published this week in the journal Nature Immunology.

Dead Brain Cells used for Research
Dead brains become source for new cells
Last Updated Mon Nov 6 15:04:26 2000
NEW ORLEANS - Scientists have discovered even cadavers can supply the incredibly versatile brain stem cells once thought to be available only from fetal tissue.
Brain stem cells are master cells that can turn into different kinds of brain and nerve cells.
Dr. Fred H. Gage of the Salk Institute at LaJolla, Calif., worked on the cadavers. His research used
bits of tissue taken soon after
death from children and young adults who had died of various neurological diseases.
His lab got the tissue 10 hours to three days after death. In every case, as well as with cells from
a man who died at 72,
researcher Theo Palmer was able to get some of the cells to divide and reproduce themselves, and to
grow into different kinds of
nervous system cells, Gage said.
Several other reports to the Society for Neuroscience are opening the field of stem cell research, and
helping researchers
bypass the ethical dilemmas involved with using human fetal tissues.
Another research team has shown skin can also supply brain stem cells, and with a bit of tweaking, so
can bones.
Ira Black of the University of Medicine and Dentistry of New Jersey, grew brain cells from cells taken
from bone marrow, where
they ordinarily would have created bone, cartilage, muscle, tendon and fat cells.
He previously reported he and his colleagues turned 80 per cent of bone marrow cells taken from rats
and humans into nerve
cells. Additional work has brought that up to more than 99 percent, Black said.
But while Dr. Ronald D.G. McKay of the National Institute of Neurological Disorders and Stroke calls
the finds 'exciting,' he warns
his findings are not yet solutions and may never be.
McKay and two colleagues warned there are big differences between stem cells from embryos, and those
from adult tissue. They
also said scientists don't yet know much about those differences.

U.S. gives go-ahead to human embryonic cell research
Last Updated Wed Aug 23 13:45:39 2000
WASHINGTON - The U.S. government on Wednesday released the guidelines that will allow the country's first federally-funded research using human embryonic stem cells.
The decision to allow such research is a controversial one because to get the cells, scientists must
destroy human embryos.
But supporters say stem cells are key in the discovery of new medical treatments and cures.
The new guidelines set out the legal, ethical and scientific criteria the U.S. National Institutes of
Health will use when it considers
applications for federal funds to study human embryonic cells.
The research involves pluripotent stem cells. They're cells that can develop into most of the specialized
cells and tissues of the
body, such as muscle cells, nerve cells, liver cells and blood cells.
Scientists say stem cells have the potential to be used to repair ailing organs and damaged tissue,
treat brain disorders, restore
severed nerves in spinal injuries, or even grow new organs for transplant.
Until now, U.S. law has prevented government funds from being used to damage or destroy human embryos.
The NIH guidelines can be found on their Web site at www.nih.gov.
Last week, a panel of experts told the British government it should support research into therapeutic
cloning, which uses
embryonic stem cells.
But at least one member of Congress is opposed to all of this. Rep. Jay Dickey says, "We're talking
about dismembering a living
being."
Scientists admit they're dealing with a fertilized human egg but they say the embryo is only a week
old and amounts to a tiny ball
of cells.

Stem cell research year's biggest story: Science
Last Updated Thu Dec 16 11:34:54 1999
WASHINGTON - Research into converting stem cells into new body parts has been chosen as the "Breakthrough of the Year" by the editors of Science, the journal devoted to scientific and medical matters.
According to the latest edition of Science, to be released Friday, stem cell technology "raises
hopes of dazzling medical
applications."
Stem cells have been considered as a way to grow replacement parts for diseased hearts, livers and other
organs. Stem cells
can also be taken from adult tissue and converted to other cells, such as brain cells becoming blood
cells.
Research into the use of embryonic stem cells to grow replacement body parts has been denounced by antiabortion
groups who
object to the use of human fetuses for this purpose.
Floyd E. Bloom, editor of Science, says in an editorial: "Although much remains to be done to convert
today's results into
tomorrow's treatments and tools, the likelihood of success seems high."

Canadian parents bank on cord blood
Last Updated Tue Dec 8 08:24:43 1998
TORONTO - Nearly 3,000 Canadian parents are using a hedge against future disease. They're banking their children's blood. But it's not just any blood; this is a sample from their baby's umbilical cord.
Some call storing cord blood a form of 'biological insurance'
It's a procedure that's growing in popularity, but it isn't cheap. Having a child's cord blood stored costs at least $650 up front and $100 a year for storage.
But it could be priceless for some parents.
Like bone marrow, cord blood has a rich supply of stem cells. They're used in transplants to treat leukemia
and other diseases.
They're a perfect match for the child, should he or she develop problems later in life. And they could
be a match for other family
members.
The blood is frozen and stored at one of three clinics in Canada.
Some call it a form of biological insurance.
The cord blood is not screened for the number of potential problems that blood available to the public
is. So it can only be used to
help family members.
Dr. John Akabutu told CBC News: "The chances of being able to use that cord blood in the
future are miniscule." He's set up
Canada's first public bank for unrelated donors. It's free. Akabutu has approached the Canadian Blood
Services about turning his
Edmonton-based bank into a national registry. The service is looking into it.
