When smell cells fail they call in stem cell reserves

/p>

"The ability to smell is crucial for eating, mating and survival, and it's important that the olfactory system be fully operational all the time," explains Reed. "The HBCs act as a fail-safe to ensure continued function of the sense of smell."

The discovery of these two distinct types of stem cells in one neural tissue is a first, says Reed, who is interested to see if other types of nerves in the body have similar repair mechanisms in play.
