A recent report has found that research on ethically-sourced adult stem cells is rising in popularity, leaving advocates pointing to its advantages – in both ethics and outcome – over embryonic stem-cell research.
The views of the scientific community are shifting with the realization
that “the best hope for rapid medical advances lies with morally
unproblematic alternatives,” said Chuck Donovan, president of the
Charlotte Lozier Institute, to the Washington Times for a Dec. 3
The Charlotte Lozier Institute is the research branch of the pro-life
Susan B. Anthony List. Recent reports by the institute have shown
significant shifts in research funding from embryonic stem cells to more
successful and ethically acceptable adult stem cells.
“Money also talks,” said one of the two reports detailing the changes in
funding, adding that “what the money is saying is that those viable
alternatives exist and it is with them that the real therapeutic promise
of regenerative medicine lies.”
Stem cell research has been the source of much controversy, both over
its potential for regenerative and potentially life-saving therapies,
and over the ethical questions in how the cells are obtained.
Stem cells taken from human embryos require the destruction of new human
life. In the past, researchers have advocated their use because they
have the potential to grow into nearly any type of tissue, making them a
kind of “master cell.”
However, in clinical trials and treatments, it has been difficult to
coax the cells to turn into a specific type of tissue. In addition,
therapies relying on embryonic stem cells have shown a tendency to turn
into tumors and cancers following treatment.
In contrast, adult stem cells come from a variety of tissues found in
newborns and adults, including the placenta, umbilical cord, bone marrow
and other bodily tissues. Their extraction does not require the
destruction of a human life.
While they naturally grow into a more narrow set of tissues than
embryonic stem cells, adult stem cells have also been induced to form
other kinds of tissues outside of their natural range. In some cases,
the stem cells can also be harvested from the patient himself, nearly
eliminating the chance of the body's rejection of the treatment.
To date, embryonic stem cells have failed to yield any successful
treatments, while adult stem cells have been used to treat more than 100
diseases and conditions.
Amid concerns over the ethics of stem cell sourcing, President George W.
Bush in 2001 restricted federal funding of embryonic stem cell research
to cell lines that already existed.
Supporters of embryonic stem cell research in California reacted with a
voter initiative pledging $3 billion in funding over 10 years only to
research on embryonic stem cells, to be distributed through grants by
the California Institute for Regenerative Medicine.
By 2012, however, funding at the institute had shifted, with a majority
of grants – totaling $50 million – going towards research on
non-embryonic stem cell projects and only $19 million in funding awarded
to embryonic research.
A similar shift in funding has taken place at Maryland's Stem Cell
Research Commission, according to a Lozier Institute report from
October. In 2007, the organization funded 11 embryonic stem cell
research projects and four non-embryonic ones. Now, it is supporting one
embryonic stem cell project and 28 non-embryonic ones.
Grants in Maryland “can also serve as an important bellwether for the
direction stem cell research is taking,” the report added, “given that
the state is home to one of the nation’s most prominent sites for stem
cell research, the Johns Hopkins University School of Medicine.”
Dr. David Prentice, senior fellow for the Family Research Council and a
researcher in cell biology, stated that researchers were told for years
“that embryonic stem cells were the 'only' stem cells for treatment as
well as lab research.”
“But even in states previously devoted exclusively to embryonic stem
cell and cloning research, the majority of grants now are going to
ethical, successful adult stem cell studies,” he commented in a
“This latest news simply emphasizes what advocates of ethical stem cell
research have said for years - adult stem cells are the true gold
standard for stem cells. They are certainly golden for patients; more
than 60,000 people a year around the world are currently treated with
adult stem cells.”
Adult stem calls research has shown “tremendous progress,” while
onic stem cell research “relies on the destruction of young human
life” and has had limited success, Prentice observed.
This offers a clear choice to researchers and investors who are looking for results, he said. “Adult stem cells save lives.”
