Piloting stem cells presents a challenge for treatments

Complications and unanticipated side-effects that have slowed the progression of stem cell studies from the lab to the clinic could soon change, researchers say.
For a decade, stem cells have tantalized scientists and patients with their promise to regenerate damaged tissues and offer treatments for incurable diseases.

No one hears, however, about the individuals who died due to complications of surgery, said Dr. Hans Keirstead, a Canadian researcher who made a paralyzed rat walk back in 2004 by injecting its spinal cord with cells derived from human embryonic stem cells.
Keirstead’s lab at the University of California-Irvine just received approval

Meat produced without animals using stem cells

If we are to produce sustainable and healthy food for the global population of nine billion people that is projected in 2050, then we must think along completely new lines.

Imagine this: With a clear conscience you sink your teeth into a juicy and tasty hamburger. No animal has been slaughtered to deliver the meat, no new forest felled to make way for animal feed, no bovine methane burps have affected the climate and no slurry has been released into the environment. The hamburger also has a satisfyingly low fat content and the fat consists only of fatty acids that

Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle

Image via Wikipedia

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers—including 2007 Nobel Prize winner Mario R. Capecchi—have created a “switch” that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. For humans, this work could lead to a genetic switch, or drug, that allows people to grow new muscle cells to replace those that are damaged, worn out, or not working for other reasons (e.g., muscular dystrophy). In addition, this same discovery also gives researchers

NeoStem, Inc., an international biopharmaceutical company with operations in the U.S. and China, today announced that it has been awarded a $700,000 contract from the U.S. Army Medical Research and Materiel Command, Telemedicine and Advanced Technology Research Center (USAMRMC-TATRC) under U.S. Army Medical Research Acquisition Activity contract number: (W81XWH-10-2-0039).

This contract is for the purpose of evaluating the use of topically applied bone marrow-derived adult mesenchymal stem cells (MSCs) for rapid wound healing. The Company previously announced that this funding was included in the Department of Defense FY09 Appropriations Bill and will begin receiving funds to initiate the

Stem cell procedure used on Utah dog; will it work?

A Richmond, Utah dog struggling for mobility is getting a new leash on life, courtesy of a new stem cell treatment for canines.
It’s not embryonic cells, but the dog’s own that are used in the treatment. North Logan vet Dr. James Israelsen of the Mountain View Veterinary Health Clinic performed the procedure on “Coty.”
Coty with Miller’s wife, Diane Bush.

“We have to harvest some fat from them to isolate the stem cells. And in her case, she’s a thin dog, so we actually harvested a little bit of abdominal fat just from the front of her
