Stem cells have the amazing potential to develop into any type of cell in the
body
...
This is the
most useful type of stem cell as these are the ones that can develop into any
type of body cell which can be used further to treat a variety of things such as
spinal cord injuries, leukaemia, Alzheimer’s and many other things
...

Stem cells are distinguished from other cell types by two important
characteristics
...

Second, under certain physiologic or experimental conditions, they can be
induced to become tissue- or organ-specific cells with special functions
...
In other organs, however,
such as the pancreas and the heart, stem cells only divide under special
conditions
...
The detailed study of the biology of
mouse stem cells led to the discovery, in 1998, of a method to derive stem
cells from human embryos and grow the cells in the laboratory
...
Many difficult questions engulf the morality of destroying embryos
or using remnants of aborted foetuses to improve the medical wellbeing of
other human beings
...
Proponents of embryonic stem cell research
argue that during the natural reproductive process human eggs often fertilize,
but fail to implant in the uterus
...
In Vitro fertilization (IVF) clinics
often create more embryos than needed over the course of fertility treatments
and the excess frozen embryos are discarded
...
Another hot topic surrounding stem cell
research is the morality of cloning humans to improve the efficacy of
techniques used to create stem cell lines
...
This method of cloning embryos is also
called SCNT and was described in detail in the previous section
...
Other crucial ethical concerns involving
issues related to stem cell donors still need to be answered
...
S
...

Another hot ethical issue is how new stem cell lines are derived
...
How would

intellectual and personal property be divided once scientists have discovered
new techniques related to stem cell therapies is an issue that has not been
completely tackled
...

Presently, many of these chronic conditions have no cure and are managed by
treating the symptoms
...
By making disease
management easier, the quality of life for those diagnosed with these diseases
and their family members would be greatly included
...

Diabetes is a chronic disease with severe complications including increased risk
for limb amputations and vision loss, and currently there is no cure
...
Deaths
attributed to diabetes is reported to be over 800,000 but many experts argue
that this figure is grossly underestimated and should be closer to 4 million
deaths per year which is nearly 9% of the world population
...
It was estimated that the total annual
economic cost of diabetes in 2002 was approximately US$132 billion or
approximately 1 out of 10 health care dollars spent in the U
...
With more
research, future treatments may include transplanting insulin-producing
pancreatic beta cells, eliminating the need for daily medications and reducing
the risk of diabetes related complications
...
S
...

Parkinson’s disease is a movement disorder with symptoms that include
debilitating tremors that continue and worsen with time
...
The varieties of medications are often
confusing, causing individuals to miss doses
...
Stem cell therapy may reduce
and prevent the progression of Parkinson’s symptoms when destroyed
dopamine-secreting neurons are replaced, improving the patient’s quality of
life and reducing drug costs
...
Of the 1
...
S
...
If that number doesn’t
open your eyes, nearly 14 million Americans have a history of heart attack or
angina, and the costs related to heart attacks exceed US$60 billion per year
...


There is remarkable new evidence that stem cells can repair a damaged heart
and the early goings suggest it is a powerful effect
...

It is important to note that this is just the beginning of trials for this
treatment and it is not clear where all of this will lead or how many patients
it might help
...

When we first met Ken Milles two years ago, he had suffered a serious heart
attack
...
They're dead
...

So he volunteered to be patient No
...
The experiment was
the brainchild of Dr
...

Fixing the heart with stem cells
Stem cells cure heart failure? What "breakthrough" study shows
"If someone's had a heart attack," said Marban, "and they have seen part of
their heart turn into scar, that is irreversible
...
"
Seeking to reverse heart injury, Dr
...
Since the heart produces so
few stem cells on its own, Dr
...

He then deposited Milles' own laboratory-grown stem cells into the damaged
area of his heart, hoping it would repair itself and beat more strongly
...
Marban to try this new approach
...

Milles was one of 25 volunteers in this small study
...
All the stem cell recipients
had their heart attack scars reduced most dramatically -- on average almost
50 percent -- damaged muscle replaced by new healthy heart tissue
...
Ken Milles had better than 50
percent improvement
...
This is where the rubber actually hits the road
...

Doctors say his heart looks almost normal again
...

"It's like someone gave me a magic pill," he said
...
It's science fiction basically to me
...
"
Now these are the first results of a unique study
...
But these
first results seem promising

For example, animal studies have
demonstrated that stem cell therapy will cause new muscle cells to be formed
through stimulation of dormant stem cells that are already inside the heart
muscle
...

At Stem Cell Institute, our stem cell treatment protocol for heart failure
involves administration of mesenchyme stem cells harvested from human
umbilical cord tissue
...
These stem cells
are expanded at Medistem Panama’s state-of-the-art laboratory
...
Each mother has her medical history

screened and is tested for infectious diseases
...

All umbilical cord-derived stem cells are screened for infectious diseases to
International Blood Bank Standards before they are cleared for use in patients
