Both NIH and Conservative Senator Back Embryonic Studies By     <A

July 18, 2001 (Washington) -- As Congress continued hearings on stem cell 
research, advocates of controversial studies using cells taken from human 
embryos gained the support of both a National Institutes of Health report and 
a prominent conservative Republican on Wednesday. 

Later this month, President Bush is supposed to announce his decision on 
federal funding for studies of embryonic stem cells. The Clinton 
administration had given the research the green light, but Bush has suspended 
that decision for a full review of the cutting-edge issue. 

The NIH report released Wednesday emphasized the merit of embryonic and less 
contentious adult stem cell research. "Both of these cell types hold enormous 
promise," the report stated. Using both cell types, scientists have been able 
to repair or replace damaged cells and tissues in animal studies, according 
to the report. 

Stem cells are "blank" cells that have the power to transform themselves into 
virtually any type of cell in the body. Scientists are hoping to harness this 
ability to battle a host of serious human diseases. 

"It is impossible to predict which stem cells ... will best meet the needs of 
basic research and clinical applications," the NIH report said. "The answers 
clearly lie in conducting more research." 

Meanwhile, Sen. Bill Frist (R-Tenn.) testified at a Senate hearing that he 
supported embryonic research under strict ethical guidelines. Frist, a heart 
surgeon and the Senate's only doctor, said, "research using the more 
versatile embryonic stem cells has greater potential than research limited to 
adult stem cells." 

Frist joins a growing list of conservatives, including Sen. Orrin Hatch 
(R-Utah) and Nancy Reagan, who back federal funding. 

According to the NIH, there are already about 30 embryonic stem cell "lines," 
which means that research stem cells have come from about 30 different human 
embryos. 

Frist said that scientists should come together to decide on an upper limit 
of cell lines that could receive federal funding. "You don't need unlimited 
cell lines," he said. Frist also emphasized that taxpayer dollars should not 
be spent for the actual extraction of stem cells from embryos, the act that 
results in their destruction. 

The early-stage human embryos in question are frozen and "left over" from in 
vitro fertilization efforts. They would otherwise be discarded. 

But the Catholic Church and many pro-life advocates are morally opposed to 
any government involvement in embryonic stem cell research, contending that 
the research requires destroying human life. Sen. Sam Brownback (R- Kan.) 
said, "We simply do not need to do any research which relies on the 
destruction of human beings." 

By contrast, Sen. Gordon Smith (R-Ore.) said that he believes that life 
begins in the mother's        womb.ButCatholicleadersinsistthatitcommences 
upon the union of the male sperm and female egg. 

A House hearing Tuesday featured testimony that opposed funding for the 
embryonic research from a couple who had adopted frozen embryos that 
ultimately were born as twins. 

Brownback and others opposed to the embryonic research say that adult stem 
cells are the only ethically acceptable scientific avenue. 

But the NIH report noted that adult stem cells are rare and that there is no 
evidence that they can develop into any other type of cell like embryonic 
stem cells can. 

It's still uncertain how President Bush will decide on federal funding for 
the embryonic research. 

Bush, who plans to meet with the Pope in Rome later this month, said this 
week that "the leaders of the Catholic Church ... stand strong on the 
principle of life. They also stand strong on making sure that those who have 
no voice are heard." 

Earlier this year, Bush wrote to a conservative group that he opposed federal 
funding for "stem cell research that involves destroying living human 
embryos." 

Even if embryonic stem cell research flourishes under possible federal 
funding, there's no guarantee of cures for cancer, Alzheimer's, Parkinson's, 
or any other of a list of diseases. 

The NIH report notes that finding a cure for type 1 diabetes may be difficult 
because the body's own immune system attacks and destroys its cells. "This 
... must be overcome if researchers hope to use the transplanted cells to 
replace the damaged ones," it says.
