A new Nature study in cancer-prone mice found that a ketogenic diet boosted small-intestinal tumors while suppressing colon tumors, and the culprit was dietary fat burning in stem cells, not ketones.
Researchers at the University of Colorado Anschutz found that the stem cells driving high-risk myelodysplastic syndromes depend heavily on the molecule NAD — a dependence that could become a precise treatment target.
Stanford researchers have found that the brain doesn't grow from one master progenitor cell as long assumed — it grows from two separate ones, a split that may trace back over 500 million years of evolution.
Personalized cell therapies have transformed cancer treatment for some patients, but they share a common problem: each dose has to be custom-built from that patient's own cells, a process that can take weeks and cost hundreds of thousands of dollars.... Continue Reading →
Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine. The... Continue Reading →
Amyotrophic lateral sclerosis (ALS) is an incurable disease of the central nervous system. In most cases, ALS is fatal within a short period following diagnosis. However, people sometimes live with the disease for decades, as did the astrophysicist Steven Hawking.... Continue Reading →
When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, John McCain experienced severe injuries as a prisoner of war during the Vietnam War -- and lost color in his hair.... Continue Reading →
The buildup of scar tissue makes recovery from torn rotator cuffs, jumper's knee, and other tendon injuries a painful, challenging process, often leading to secondary tendon ruptures. New research led by Carnegie's Chen-Ming Fan and published in Nature Cell Biology reveals the... Continue Reading →
New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness - by softening the tissue hosting the stem cells which then helps repair wounds, inside the body. The team... Continue Reading →
