Fetal tissue fact sheet
- UNMC’s fetal cell
research seeks to understand how brain cells are damaged and to find ways to
regenerate these damaged brain cells in neurodestructive diseases, such as
Alzheimer’s disease, Parkinson’s disease, multiple sclerosis and AIDS-related
dementia.
- This research is very important to the state
of Nebraska, which ranks among the top four states in the
percent of people age 85 years and older. In total, these neurodestructive
diseases affect more than 5 percent of Nebraska’s population.
- Alzheimer’s disease alone affects 4 million
people nationally. That number is expected to double by 2030. Currently, about
77,000 Nebraskans have Alzheimer’s disease – enough people to fill Memorial
Stadium in Lincoln.
- Research using fetal cells has been conducted
nationally since the 1930s. For example, in 1954, human fetal cells were
instrumental in the development of the polio vaccine.
- Most hospital diagnostic virology labs use
cell lines derived from an aborted fetus as a diagnostic tool in identifying
certain viral infections. These infections include viruses that cause
influenza, diarrhea, encephalitis, meningitis and pneumonia.
- Other fetal cell lines have been used to grow
the virus used for vaccines to prevent hepatitis A, chicken pox and rubella
(German measles).
- During the past three years, the National
Institutes of Health (NIH) has provided funding for nearly 300 research
projects in the U.S. using fetal cells. In addition to UNMC, at
least 48 other academic health sciences institutions have received funding for
fetal cell research during that period. These research projects involve
academic health sciences centers around the country, including such leading
public universities as the University of Michigan, the University of
Pennsylvania and the University of California at Berkeley, as well as
neighboring institutions such as the University of Iowa, the University of
Colorado Health Sciences Center, and the University of Minnesota.
- On February 1, 2001, a federal
study headed by the University of Colorado Health Sciences Center found that
fetal tissue implanted in patients with advanced Parkinson’s disease was
successful in helping many recipients regain lost mobility or in allowing them
to reduce or even stop their medications.
- On December 1, 2000, researchers
at Harvard Medical School, Emory University, the University of South Florida,
and Rush Presbyterian Medical Center in Chicago reported that five patients
with Huntington’s disease demonstrated measurable progress at least one year
after they received fetal tissue implants. Huntington’s disease is a
degenerative neurological disorder that produces severe physical and
psychiatric problems before eventually resulting in the individual’s death.
- At UNMC, a woman being treated for
AIDS-related dementia directly benefited from fetal cell research. After fetal
cell studies determined that ibuprofen could reduce the inflammation in her
brain, she was given this drug in combination with others and made a
remarkable recovery after being very near death. The recovery was written up
in scientific journals.
- Data from fetal cell research conducted at
UNMC and other institutions influenced the National Institutes of Health (NIH)
to issue a Request for Proposals to better understand the role of the immune
response in Alzheimer’s disease.
- UNMC has a long history of conducting research
in neurodestructive diseases, such as Alzheimer’s. Only 5 to 10 percent of
this research at UNMC involves the use of fetal cells. Other research areas in
neurodestructive diseases that don’t involve the use of fetal cells include:
numerous drug studies, a geriatric assessment program, and a clinic for memory
disorders.
- Ordinarily, all of the fetal tissue would be
incinerated and not used for any purpose. In this case, instead of discarding
all of the tissue, a tiny sample of neural cells is provided to UNMC
researchers.
- UNMC currently receives all of its fetal
tissue from the University of Washington Birth Defects Research
Laboratory in Seattle. This laboratory is funded by the National Institutes of
Health and has provided tissue to scientists for nearly 40 years. Since its
inception, the laboratory has provided tissues to nearly 50 universities and
research institutes.
- The University of Washington (UW) tissue
program is a major supplier of embryonic and fetal tissue for NIH-funded
investigators and operates in full compliance with all relevant laws and
regulations, including those of the American Association of Tissue Banks. The
tissue program can supply tissues only for grant-funded research in
laboratories based at universities and non-profit research institutes. The
tissue comes from non-viable embryos and fetuses.
- With the UW tissue program, no inducement,
monetary or otherwise, is ever given to either clinics or patients for tissue
donation. Patients receive information sheets and, before donating tissue,
sign informed consent forms. The donation of tissue is completely free-will.
Tissues donated would otherwise be discarded. Laboratory personnel never have
contact with any patient at any time.
- The UW provides the tissue only to
grant-funded investigators at no cost. A $100 collection and processing fee is
charged irrespective of the number of tissue samples obtained at any one time.
No tissue is distributed to pharmaceutical companies or biotechnology firms.
- The collection and processing fee was mandated
by the NIH two years ago to cover the laboratory’s expenses in collecting and
processing the tissue. The same fee is charged to all universities and
research institutes. Prior to this NIH mandate, the tissue had been provided
at no cost and with no collection/processing fee.
- UNMC has made a strong commitment to finding
cells from alternative sources other than elective abortions. It has been
determined that rapid brain autopsies performed within two hours of a person’s
death are the best option for procuring the necessary cells. UNMC has invested
more than $700,000 to provide the infrastructure to develop alternative
sources to the use of fetal cells in important research. An additional
$100,000 was allocated in fiscal year 2003-04.
- Since starting its rapid brain autopsy
program, UNMC has been successful in procuring two of the three necessary
cell types from the rapid autopsy procedure. The two cells obtained are the
astrocytes and microglia, two of the support cells for neurons. Currently,
UNMC has been unable to procure usable neurons from the rapid autopsy
procedure. Neurons are the nerve cells in the brain that receive and send out
electrical signals throughout the body.
- The rapid autopsy procedure has been performed
on a broad age spectrum from neonates to people in their 80s. This has allowed
UNMC to conduct a variety of comparative studies looking at changes in the
brain at various ages – something that couldn’t be done when UNMC was only
using fetal tissue.
- Contrary to the statements of opponents of
this research, viable scientific alternatives to the use of fetal cells are
not yet available in order to conduct the research ongoing at UNMC.
- Although federal law does not require
institutions to review fetal cell research that does not involve patients,
UNMC scientists using neural fetal cells in laboratory or mouse research
requested a review of this research. The research was then reviewed by two
campus committees, which included community members, and the executive
committee of UNMC’s Institutional Review Board (IRB).
- UNMC researchers have attempted to share their
research findings. More than 60 papers and an equivalent number of abstracts
have been published in major scientific journals since the fetal cell research
began eight years ago. Eleven grants were awarded by national societies and
the federal government to support these works.
- Without exception, each grant was reviewed at
least once and several were reviewed two or three times. Research findings
have been delivered at regional and national scientific conferences as well as
through meetings held at UNMC. These research presentations were delivered by
students, faculty and fellows.
- Tours of the laboratories and the Center for
Neurovirology and Neurodegenerative Disorders (CNND) are available upon
request. Since 1995, there have been several news releases on key articles and
other initiatives.
