Molecular switch controls ability to repair hearing loss in mice

In a study in mice, Johns Hopkins Medicine researchers have found a molecular switch that turns off the animal's ability to repair damaged cells in the inner ear. The findings shed light on regenerative abilities that are ...

Fine-tuning stem cell metabolism prevents hair loss

A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair loss: hair follicle stem cells, essential for hair to regrow, can prolong their life by switching their metabolic state in response ...

Researchers identify microRNA that shows promise for hair regrowth

Researchers from North Carolina State University have identified a microRNA (miRNA) that could promote hair regeneration. This miRNA—miR-218-5p—plays an important role in regulating the pathway involved in follicle regeneration, ...

Scientists find a simpler way to make sensory hearing cells

Scientists from the USC Stem Cell laboratories of Neil Segil and Justin Ichida are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce ...

Researchers grow hairy skin from human stem cells

For more than 40 years, scientists and commercial companies have been recreating human skin in laboratories around the world. Yet all of these products lack important aspects of normal skin—hair, nerves, and fat.

'Chemical earmuffs' could prevent hearing loss

Once you start to lose your hearing, you can't get it back. But what if you could prevent hearing loss by blocking in advance the effects of loud noises?

Hair growth finding could make baldness 'optional'

The best way to avoid baldness is to stop hair from falling out in the first place. Now, researchers say a new hair growth discovery might help men keep their locks for a lifetime.

Lymphatic system found to play key role in hair regeneration

Given the amount of wear and tear it's subjected to on a daily basis, the skin has a phenomenal ability to replenish itself. Spread throughout it are small reservoirs of stem cells, nested within supportive microenvironments ...

Outer hair cells regulate ear's sensitivity to sound

The ear's tiny outer hair cells adjust the sensitivity of neighbouring inner hair cells to sound levels rather than acting like an amplifier, suggests a new study published today in eLife.
