Stem cells take aim at body’s top three killers
By Dick Pelletier
In two recent PBS programs,
Innovations and Charlie Rose, experts declared
we are at war with the three leading causes of death in America
– heart disease, cancer, and obesity.
The challenges are enormous,
researchers said, but all were confident we could win this war.
Within the next decade, they claimed, death from all three of
these horrible diseases could be eliminated. The diseases may
not be completely cured during this time, they cautioned, but
drugs will be available to prevent all the pain, suffering, and
death that these killers now dish out.
Stem cells are rapidly
becoming the "magic bullet" of choice in our war against killer
diseases. Scientists are identifying the genetic signals that
instruct stem cells to grow new tissues in hearts, bones,
brains, skin, and other body parts.
However all is not clear
sailing with this revolutionary science. Although stem cells
offer tremendous potential to fight disease and save lives, the
Bush administration has denied federal funding for embryonic
stem cell research based on a controversial belief that an
embryo created in the lab as a medical tool represents a human
life that should not be destroyed.
Many religious doctrines state
that "life begins at conception." When researchers clone an
embryo and extract stem cells, its activities cease. This,
opponents say, destroys a potential human life. Advocates
counter that the embryo never achieves "personhood;" it is only
a medical tool created to save human lives.
The Bush policy has forced
some patients to seek help in foreign countries. Terminally ill
ALS patient Drew Schemera recently traveled to Beike Biotech
in China where he received injections costing $42,500.
Explaining his decision, Schemera said, "There were no clinical
trials in the US of any significance and no cure on the
horizon." So I thought that doing something was better than just
waiting around to die.
Truly, the US healthcare
system, which now exceeds more than $3.2 trillion in costs
annually, needs to change. And biotechnologist Leroy Hood,
founder of the Institute for Systems Biology believes
he knows what some of the changes will be. The 69-year-old
visionary says that medical care will shift from treating
illness (reactive) to managing health (proactive).
Hood sees the following
changes over the next decade:
Personal genomes
– the cost of genome sequencing is now under $1,000. Doctors can
soon inexpensively determine a patient’s probability of
developing diseases and prescribe therapies to prevent most
illnesses from ever happening, which will replace today’s
trial-and-error approach.
Changing habits
– drugs will soon be available that blunt the desire to overeat,
drink, smoke, or act hostile. This could extend average healthy
lifespans by 30 years or more.
Patients in charge
– people will maintain their own health; not just by treating
existing illnesses, but by becoming aware of weaknesses in their
genome, which will enable them to avoid major health problems in
the future.
Could this "magical future"
ever become reality? Positive futurists believe that during the
next decade, 2010-to-2020, biotech advances and new healthcare
approaches will allow doctors to replace aging skin, bone, and
organs at affordable prices, thus restoring many ‘boomers and
seniors (hopefully including this writer) to a healthy, more
youthful state.
