Labyrinth supporting cells

Labyrinth supporting cells are a type of cell found in the inner ear that play a crucial role in the function and maintenance of the sensory hair cells. These cells are part of the labyrinth structure of the inner ear, which is responsible for our sense of balance and hearing.

Function

Labyrinth supporting cells provide both structural and functional support to the sensory hair cells. They help in maintaining the homeostasis of the extracellular fluid in the inner ear, which is essential for the proper functioning of the hair cells. They also play a role in the regeneration of damaged hair cells, a process that is crucial for maintaining our hearing and balance capabilities.

Types

There are several types of labyrinth supporting cells, each with their own specific functions. These include:

• Deiters' cells: These cells provide physical support to the outer hair cells in the cochlea. They also play a role in the active process of the cochlea, which enhances our ability to hear quiet sounds and discriminate between different frequencies.

• Hensen's cells: These cells are found in the cochlea and are thought to play a role in the regulation of potassium levels in the extracellular fluid.

• Claudius cells: These cells are also found in the cochlea and are believed to be involved in the secretion and absorption of the extracellular fluid.

Clinical significance

Damage to the labyrinth supporting cells can lead to a loss of function in the sensory hair cells, resulting in hearing loss or balance disorders. Research is currently being conducted to understand the potential of these cells for regenerative medicine, with the aim of developing treatments for hearing loss and balance disorders.
