Stem Cells Restore Memory in Mice
By Steven Reinberg
HealthDay ReporterWed Oct 31, 7:00 PM ET
WEDNESDAY, Oct. 31 (HealthDay News) -- A new U.S. study involving mice
suggests the brain's own stem cells may have the ability to restore
memory after an injury.
These neural stem cells work by protecting existing cells and promoting
neuronal connections.
In their experiments, a team at the University of California, Irvine,
were able to bring the rodents' memory back to healthy levels up to
three months after treatment.
The finding could open new doors for treatment of brain injury, stroke
and dementia, experts say.
"This is one of the first reports that you can take a stem cell
transplantation approach and restore memory," said lead researcher
Mathew Blurton-Jones, a postdoctorate fellow at the university. "There
is a lot of awareness that stem cells might be useful in treating
diseases that cause loss of motor function, but this study shows that
they might benefit memory in stroke or traumatic brain injury, and
potentially Alzheimer's disease."
In the study, published in the Oct. 31 issue of the Journal of
Neuroscience, Blurton-Jones and his colleagues used genetically
engineered mice that naturally develop brain lesions. The researchers
destroyed cells in a brain area called the hippocampus. These cells are
known to be vital to memory formation and it is in this region that
neurons often die after injury, the researchers explained.
To test the mice's memory, Blurton-Jones's group conducted place and
object recognition tests with both healthy mice and brain-injured mice.
Healthy mice remembered their surroundings about 70 percent of the time,
while brain-injured mice remembered it only 40 percent of the time. For
objects, healthy mice recalled objects about 80 percent of the time, but
injured mice remembered them only 65 percent of the time.
The researchers then injected each mouse with about 200,000 neural stem
cells.
They found that mice with brain injuries that received the stem cells
now remembered their surroundings about 70 percent of the time -- the
same as healthy mice. However, mice that didn't receive stem cells still
had memory deficits.
The researchers also found that in healthy mice injected with stem
cells, the stem cells traveled throughout the brain. In contrast, stem
cells given to injured mice lingered in the hippocampus. Only about 4
percent of those stem cells became neurons, indicating that the stem
cells were repairing existing cells to improve memory, rather than
replacing the dead brain cells, Blurton-Jones's team noted.
The researchers are presently doing another study with mice stricken
with Alzheimer's. "The initial results are promising," Blurton-Jones
said. "This has a huge potential, but we have to be cautious about not
rushing into the clinic too early."
One expert is optimistic about the findings.
"Putting in these stem cells could eventually help in age-related memory
decline," said Dr. Paul R. Sanberg, director of the Center of Excellence
for Aging and Brain Repair at the University of South Florida College of
Medicine. "There is clearly a therapeutic potential to this."
Sanberg noted that for the process to work with Alzheimer's it has to
work with older brains. "There is clearly therapeutic potential in
humans, but there are a lot of hurdles to overcome," he said. "This is
another demonstration of the potential for neural stem cells in brain
disorders."

Sure Berg, according to you babies should die so nitwits like yourself
can feel mentally superior to a mouse.

*yawn*
Well, look here: speaking of mice, here's "J Young", the Lappcatt!
So...in your demented mind, stem cells = babies?
That's a good one!
In any event, how come you've *once again* made a challenge, and then *run
away* like the whupped coward you are, J/IBen/Auric?
Have at it, boy!: Message-ID: <fg7csr09ut@enews5.newsguy.com>

"Embryonic" stem cells are actually harvested from blastocysts that
are being disposed of. So they die whether the stem cells are
harvested or not.

Now there you go again, Al, confusing IBen with facts.

True facts, yet, as opposed to the false facts he usually posts - the
few times he post any facts at all.

Goodfact, rather than realfact. Gotta love Bab 5, with an aside to Orwell. :)

Haven't watched it since the first season.

As opposed to you, for whom there's no hope?
