Indirect immunohistochemistry was used to image and allow morphological characterization of the hair cells
. The tissue sections were rinsed three times for 5 min in BSA/ PBST (1% bovine serum albumin and 0.1% Triton X-100 in PBS; Sigma Aldrich, St.
Teens need to realize that we only have a set number of inner ear hair cells
. They do not grow back.
But new research reveals that supporting cells in the ear can turn into hair cells
in newborn mice.
The cause is mostly damage to the inner hair cells
specialized sensory cells in the inner ear that transmit information about sounds through the nervous system to the brain.
biotech GenVec to develop gene-based treatments to replace hair cells
in the ear that transmit sound.
When it's moving at the same speed as you, the hair cells
no longer send a signal to the brain.
While scientists are still looking into ways of possibly reviving damaged hair cells
, the predominant treatment approaches for NIHL now are hearing aids or cochlear implants.
Mice lacking FGF20 were missing about two thirds of their outer hair cells
. However, the number of inner hair cells
which transmit amplified sound signals to the brain, appeared normal.
Humans are born with 30,000 hair cells
in each ear.
The work holds out the prospect of regenerating the sensitive hair cells
that turn sound vibrations into nerve signals.
The cellular basis for aminoglycoside hearing loss is a destruction of cochlear hair cells
, specifically the outer hair cells
"These hair cells
are like well-engineered mechanical sensors, similar to those that we use for balance and hearing in the human ear, where the deflection of the jelly-encapsulated hair cell
measures important flow information," he said.
