Salk scientists say their findings may lead to strategies to treat age-related diseases and improve regenerative medicine Stem cells are essential building blocks for all organisms, from plants to humans. They can divide and renew themselves throughout life, differentiating into the specialized tissues needed during development, as well as cells necessary to repair adult tissue. Therefore, they can be considered immortal, in that they recreate themselves and regenerate tissues...

A Japanese research team has developed a promising new treatment for heart failure by growing sheets of new heart muscle tissue from stem cells. When implanted in damaged rat hearts, the bioengineered tissue improved heart function. The study, led by Dr. Kenji Miki, a cardiovascular surgeon at Osaka University Graduate School of Medicine, appears in the May issue of STEM CELLS Translational Medicine. Durham, NC (PRWEB) May 17, 2012 A Japanese research team has developed a promising new...

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) have discovered that mice that lack a gene called Snf2l have brains that are 35 per cent larger than normal. The research, led by Dr. David Picketts and published in the prestigious journal Developmental Cell, could lead to new approaches to stimulate brain regeneration and may provide important insight into developmental disorders such as autism and Rett syndrome. Dr. Picketts and his team...

This summer's action film, "The Amazing Spider-Man," is another match-up between the superhero and his nemesis the Lizard. Moviegoers and comic book fans alike will recall that the villain, AKA Dr. Curt Connors, was a surgeon who, after losing an arm, experimented with cell generation and reptilian DNA and was eventually able to grow back his missing limb. The latest issue of the journal Physiology contains a review article that looks at possible routes that unlock cellular regeneration in...

Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant. The study, published online April 26 in the journal Circulation Research, used molecules called microRNAs to trigger the cardiac tissue conversion in a lab dish and, for the first time, in a living mouse, demonstrating the potential of a simpler process for tissue regeneration....

For the first time, researchers have converted scar tissue that forms after a heart attack into regenerated heart muscle using microRNA, according to an animal study reported in Circulation Research, an American Heart Association journal. After a heart attack, heart muscle doesn't easily regenerate and it accumulates scar tissue, made up of cells called fibroblasts – increasing risk for heart failure. "Researchers have tried various approaches, including the use of stem cells, to...

Tulane team's research may hold promise for veteran amputees, diabetics, accident victims A research team at Tulane University will report this week that the application of high levels of oxygen to a severed bone facilitates bone regrowth, study results that may one day hold promise for injured soldiers, diabetics and other accident victims. The results of the Department of Defense-funded study will be presented at 12:25 p.m. Monday April 23, at the American Society for Biochemistry and...
