WHEN SMELL CELLS FAIL THEY CALL IN STEM CELL RESERVES

WHEN SMELL CELLS FAIL THEY CALL IN STEM CELL RESERVES: "Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear online next week in Nature Neuroscience."
