In a medical first, University researchers have created a beating heart in the laboratory. Using detergents, they stripped away the cells from rat hearts until only the nonliving matrix, or “skeleton,” was left; they then repopulated the matrix with fresh heart cells.
If perfected, the technique may be used someday to generate new hearts for patients. In the United States alone, about 5 million people live with heart failure, 550,000 new cases are
Some Steamboat Springs residents are forgoing the Tooth Fairy, hoping their teeth wind up being worth much more than a quarter.
Steamboat Springs oral surgeon Dr. John Lupori offers patients the chance to store the stem cells in the teeth he extracts. Lupori partners with StemSave, a New York-based company that freezes and stores stem cells found in the pulp at the base of teeth. Science is moving fast, those involved said, and the cells might someday save the patient’s life.
“Potentially, they’re incredibly miraculous,” said Dr. Bob Pensack, who had his daughter, Miriam, save her cells. “They’ve already been miraculous
