stem cell regeneration break through
Single stem cells repair tissue damage STANFORD, Calif. (UPI) -- U.S. researchers say they've demonstrated a single adult stem cell can self-renew in a mammal and repair damaged tissue.
Stanford University Professor Helen Blau and researchers Alessandra Sacco and Regis Doyonnas said they transplanted skeletal adult muscle stem cells into special immune-suppressed mice whose muscle satellite cells and been destroyed in a hind limb by irradiation.
The scientists also genetically engineered the transplanted stem cells to express Pax7 and luciferase proteins. As a result, every transplanted cell glowed under ultraviolet light and was easy to trace.
"To be able to detect the presence of the cells by bioluminescence was really a breakthrough," said Blau. "It taught us so much more. We could see how the cells were responding, and really monitor their dynamics."
Sacco said the researchers were thrilled with the results. "It's been known that these satellite cells are crucial for the regeneration of muscle tissue, but this is the first demonstration of self-renewal of a single cell."
The scientists said the ability to isolate and then transplant skeletal adult muscle stem cells could have a wide impact in treating not only a variety of muscle wasting diseases such as muscular dystrophy, but also severe muscle injuries or loss of function from aging and disuse.
The research was presented last week in San Francisco during the annual meeting of the American Society for Cell Biology.

regeneration
heal thyself.
Army scientists examine body self-healing WASHINGTON (UPI) -- The saw "Physician, heal thyself" may yield to "Body, heal thyself" as U.S. army scientists study skin regeneration and other self-healing technologies.
Regenerative science was one of several technologies showcased at the recent 26th Army Science Convention in Orlando, Fla. The 4-day gathering provides a form to exchange ideas and highlight collaborative projects between Army research labs, universities and business partners, CNN reported Monday.
The Army's regenerative medicine study combined properties from the intestinal lining and the urinary bladder to create a regenerative substance called Extracellular Matrix, a crystal substance that boosts the body's tendency to repair itself, U.S. Army Biological Scientist Sgt. Gen Rossman told CNN. When applied to a missing digit or limb, "the body thinks it's back in the womb," Rossman said.
Through both animal studies and human clinical trials, the institute is developing therapies for soldiers injured by roadside bombs and other explosives in Afghanistan and Iraq, CNN said.
"We are working on trying to regenerate limbs, to repair limbs and to keep them from being amputated," said Col. Bob Vandre, project director for the Armed Forces Institute of Regenerative Medicine.
Armed Forces Institute scientists said they also developed a process to rebuild missing or damaged bone.
