A Canadian-led international team of researchers has begun solving the mystery of just how a specialized cell taken from a person's skin is reprogrammed into an embryonic-like stem cell, from which virtually any other cell type in the body can be generated.
A Bulgarian man who was paralyzed from the chest down after a knife attack is miraculously able to walk again after undergoing a pioneering stem cell transplant surgery, in what scientists are hailing as “a breakthrough.”
Canadian researchers have found a way to boost the number of stem cells from umbilical cord blood so more patients with leukemia and other blood-related cancers can receive potentially life-saving transplants.
Canadian doctors have begun using stem cell transplants to treat "stiff person syndrome," a rare neurological condition in which a patient's leg and other muscles suddenly contract painfully, often leaving them immobilized like a tin soldier.
Scientists implanted thin sheets of scaffolding-like material from pigs into a few young men with disabling leg injuries -- and say the experimental treatment coaxed the men's own stem cells to regrow new muscle.
