While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

Researchers have identified the biological mechanism of how chronic stress leads to hair loss. They found that the stress hormone corticosterone causes hair follicle stem cells to stay in an extended ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

A study links graying hair to stem cells getting stuck, unable to color new hair growth. Stem cells travel back and forth within compartments, but when they get stuck in one compartment, they cannot ...

The inner ear is a highly specialised sensory organ responsible for converting mechanical sound waves into neural signals through mechanosensitive hair cells. Despite their essential role in hearing, ...

In the zebrafish inner ear, a cell type known as supporting cells (magenta) gives rise to new sensory hearing cells (blue). The study reveals a set of DNA control elements critical for supporting ...

Hair cells in the inner ear detect mechanical stimuli from sound waves and convert them into electrical signals that the brain can interpret. Some animals, such as zebrafish, can regenerate their ...
