Rats' mobility
restored in CU

Support cells strained from human stem cells and
transplanted into paralyzed lab rats repair
damaged nerve systems remarkably quickly and
help the rats walk again, according to CU
researchers, who say the experiments could
extend to injured humans within two years.

Working with University of Rochester scientists,
University of Colorado School of Medicine
researchers made "a huge step" in treating
spinal-cord injuries, according to a paper
published in the peer-reviewed online journal
PLoS ONE.

The rapid improvement in paralyzed rats has
"very exciting" possibilities to repair other
nervous-system damage from strokes, traumatic
brain injury, and Parkinson's, Alzhei mer's and
Lou Gehrig's diseases, said CU medical-school
researcher Stephen Davies.
"We were able to show that we could bring near-
complete restor ation of normal movement,"
Davies said.

Previous studies have shown that isolating the
same form of rat cells for transplant can bring
improvements in rats, but the latest step
advances to using human stem cells and an
isolate called astrocytes, said lead study author
Chris Proschel, assistant professor of genetics at
the University of Rochester Medical Center.

"What's really striking is the robustness of the
effect," Proschel said. "Scientists have claimed
repair of spinal-cord injuries in rats before, but
the benefits have been variable and rarely as
strong as what we've seen with our transplants."

The research isolated cells called astrocytes
from human stem cells. Previous experiments
assumed less-refined stem cells could be
transplanted with good results; the Colorado-
Rochester experiments found that by turning the
stem cells into the right form of astrocytes
before transplant, improvements in the injured
rats came much more quickly and reliably.

The researchers will now branch out their testing
on rats, implanting the isolated form of cell to
target more severe and complex spinal-cord
injuries. They also will pursue eventual clinical
tests on injured humans, meanwhile trying to
cultivate usable cells from adult or preapproved
embryonic stem-cell lines.

"Now the challenge is how rapidly can we
translate these discoveries from the lab for use

Amazing and scary.

Sinner, it will be in our lifetimes that we will use stem cell technology to grow pigs that are custom created for YOU and your medical needs. A transgenic pig will have kidneys, lungs, heart, pancreatic islet cells.....like a second junker sitting out by the barn to part out to your first car.

Heart disease, renal failure/dialysis, diabetes, many forms of cancer....all will be treatable.

But at what cost? Available to whom? And who's gonna pay?

And who's gonna feed dem hogs?

As the parent of a 12 year old thats been diabetic since 3, whatever it takes. Absolutely whatever it takes. Hes been through enough

I am aware that some do oppose stem cells. I just can't understand why

Is it simply the "slippery slope" argument carried to an extreme? Or is there something more to it that I'm missing?

your thesis is flawed. there is little resistance to stem cell research. there is resistance to embryonic stem cell research.

BTW, I believe former President George W. Bush is the first president to actually fund embryonic stem cell research.

I think the resistance to embryonic stem cells comes from the extreme end of the anti-abortion crowd. They are afraid that women will get pregnant just in order to have a human embryo aborted in order to harvest (and sell) the stem cells.
Personally, I think that there are more than enough "legal" abortions to supply huge amounts of embryonic stem cells.

Its right wing Christian extreme conservatism. Notice they're backing away from this pretty quickly, as they see the benefits.

Interesting that a physician would call doing no harm to a fetus "right wing Christian extreme conservatism". And there are PLENTY that are not backing away from it, but label it however you please, but just because it is an apposing view to yours does not make it "extreme."

Your own statement about the potential future use of stem cells also should acknowledge the potential that there could indeed be better ways to harvest these potent cells than from the "fruit" of an abortion.

With the liberals losing the argument all over the country and especially at the polling booth, they are becoming more and more unhinged as referenced by DNF referring to everything he disagrees with as extreme. The libs are actually showing their true colors every day now. Can't wait for the next couple of election cycles to see them pop their eyeballs out just a little more.
