Adult spiral ganglion cells are unable to regenerate and thus, cannot be used to repair hearing loss. The recent research evidence in a mouse model showed that stem cells of spiral ganglion are capable of self-renewal and thus, can be grown and induced to differentiate into mature spiral ganglion cells as well as neurons and glial cells. Jane Taylor, the BioResearch Open Access Editor from University of Edinburgh, Scotland said ‘The current findings are of great interest as they show that the stem cells of inner ear can be induced to grow in-vitro.’ He added that the ear cells are generally poorly regenerated in case of the mammalian ear.

The researchers concluded that the self-renewing properties of the spiral ganglion stem cells are a ray of hope for those with hearing impairment. They said that these stem cells offer a promising source of replacement therapies that are designed to regenerate the neural structures of the inner ear. The findings appeared in the journal BioResearch Open Access. (Read:Hearing aids: All your common queries answered)
