When smell cells fail they call in stem cell reserves

“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.
