Human stem cells heal the hearts of rats |
And idiot Bush still wants restrictions on such work.

Human stem cells heal the hearts of rats
By Maggie Fox, Health and Science EditorSun Aug 26, 2:51 PM ET
A nutritious cocktail helped human embryonic stem cells thrive and
repair the damaged hearts of rats, U.S. researchers reported on Sunday.
The experiment provides the best evidence yet that the powerful but
controversial stem cells might be used to repair the ravages of heart
attacks and heart failure, the researchers said.
Biotechnology company Geron Corp said it would try to develop the cells
into a product. "We're developing our cardiomyocyte product, GRNCM1, to
address the large unmet need in heart failure," said Dr. Thomas Okarma,
president and chief executive officer of Geron.
Stem cells are the body's master cell, acting as a source for the
various cells and tissues in the body. Those taken from days-old
embryos, called embryonic stem cells, are the most malleable and can
produce all of the cell types.
Their use is controversial because some people oppose the destruction of
a human embryo. U.S. President George W. Bush has kept strict limits on
federal funding of human embryonic stem cell research. There are no
restrictions on privately funded researchers.
Okarma said embryonic stem cells were the only human stem cells that had
been shown to form cardiomyocytes -- heart muscle cells.
Because embryonic stem cells are so immature, it is very difficult to
control what kinds of cells they produce, and the fear is that a tooth
could grow inside a heart, for instance.
"We got stem cells to differentiate into mostly cardiac muscle cells,
and then got those cardiac cells to survive and thrive in the damaged
rat heart," said Dr. Chuck Murry of the University of Washington's
Institute for Stem Cell and Regenerative Medicine, who worked on the
study.
But the cells died when they injected them into the hearts of the rats,
the researchers reported in the journal Nature Biotechnology.
COMMON PROBLEM
"This problem is not unique to our system. Death of transplanted cells
is slowing research progress in cell therapy for diabetes, Parkinson's
disease and muscular dystrophy, among other diseases," they wrote.
So the team developed what they dubbed a "survival cocktail" that
included various proteins and other compounds to stop the cells from
dying.
It worked. When they caused heart attacks in the rats and then injected
the new heart muscle cells, every graft survived and integrated into the
hearts of the rats.
They beat in rhythm and improved the heart function of the rats, they
reported.
"This is one of the most successful attempts so far using cells to
repair solid tissues -- every one of the treated hearts had a
well-developed tissue graft," Murry said.
This is key to treating someone after a heart attack, known medically as
a myocardial infarction, said Dr. Michael Laflamme, who also worked on
the study.
"This sort of treatment could help the heart rebound from an infarction
and retain more of its function afterwards," Laflamme said in a
statement.
An estimated 865,000 people have heart attacks in the United States
every year and more than a third eventually develop heart failure, a
chronic condition in which the heart fails to pump blood properly. A
third of heart failure patients die within two years.

Let's hope his heart fails, and he refuses to be saved by "killed
babies". Not that he's honest enough to do anything like that.

Are you kidding? He'll probably go running to Britain, Singapore, or
someplace where such research is legal to get healed, while thousands
who can't afford to travel will die.

He keeps it in Cheney's chest, since he has no actual use for it.

Of course. He keeps it locked up in a treasure chest.

Dubya has a heart?
That's news to me...

I don't know about a heart, but lack of brain tissue is more of a
concern to me.

Heh! I can see Cheney blowing his nose and stuffing the used tissue in
Dubya's ear.
