Scientists say that they have developed a method to use modified messenger RNA to lengthen telomeres, opening a pathway to countering the effects of aging in cells--a process that might apply to a range of diseases from DMD to diabetes and heart disease.
Pancreatic cancer has long loomed as one of the most aggressive killers, typically leaving patients with a poor prognosis and specialists with few options for effective treatment. But now a team at the University of Michigan in Ann Arbor says they have new reason to believe that a particular gene is responsible for the fast-spreading cancer--offering a clear target for drug developers.
CRISPR technology's potential for gene editing has helped inspire the launch of a trio of closely watched biotech startups with their sights set on some cutting-edge approaches to new therapeutics. And now a team at Johns Hopkins has done some experiments to demonstrate its promise in engineering human stem cell therapies.
Two prominent researchers whose work on stem cells has come under review have fired back at Harvard Medical School and Brigham & Women's Hospital in a lawsuit, blaming a coauthor for the problems that triggered one paper to be retracted and another questioned while claiming that the university mishandled its investigation into their efforts.
Stem cell investigator Haruko Obokata has resigned from Japan's RIKEN Center for Developmental Biology some months after a paper she co-authored on a new method to create pluripotent stem cells was retracted.
A research team says it has developed a new type of stem cell--capable of developing into any kind of tissue--that could pave the way to new cell lines that could be made more efficiently, opening up its potential in R&D.
Researchers have hit on a new approach to creating functional melanocytes, the body's pigment-producing cells. And their work could spur a fresh approach to screening and developing new drugs for melanoma as well as producing new cell-based therapies for a variety of skin diseases.
Working around the notion that cancer-causing mutations on receptors found in bone marrow stem cells could explain why some patients grow resistant to currently used leukemia drugs, researchers at the Indiana University School of Medicine say they've been successful in testing a new approach to fighting the disease.
Using human pluripotent stem cells, scientists at Cincinnati Children's Hospital Medical Center have grown functional 3D human stomach tissue for the first time.
Scientists have figured out a way to harness stem cells so that they can be used to produce and emit toxins capable of killing brain tumors.
