Four boys with a rare and often fatal brain disease were implanted with stem cells that began fixing damage that impeded their ability to walk, talk and eat, a trial found. Twelve months after the surgeries, the boys have more myelin — a fatty insulating protein that coats nerve fibers and speeds...

Two scientists who upended fundamental beliefs about biology by demonstrating that every cell in the body has the potential to grow into every other type of cell have won the Nobel Prize in physiology or medicine. Sir John Gurdon and Dr. Shinya Yamanaka were honored Monday for "the discovery that...

Japanese researchers have discovered a potential cure for some forms of infertility by using stem cells to create viable eggs in living mice. While the method, reported in the journal Science, is far from being ready for possible human use, it did overcome a key challenge in reproductive medicine:...

An international team of scientists have identified for the first time a key factor responsible for declining muscle repair during aging, and discovered how to halt the process in mice with a common drug. Although an early study, the findings provide clues as to how muscles lose mass with age, which...

Researchers at Moffitt Cancer Center have discovered that the micro ribonucleic acid miR-214 plays a critical role in regulating ovarian cancer stem cell properties. This knowledge, said the researchers, could pave the way for a therapeutic target for ovarian cancer. The study appears in a recent i...
