Human Senses Pictures Hair cells within the inner ear contain bundles of hair-like extensions that convert sound. The new approach involves reprogramming inner ear cells by inhibiting a protein called Notch.Previous laboratory research had shown that Notch signals help prevent stem cells in the cochlea transforming themselves into new sensory hair cells. Lead researcher Dr Albert Edge, from Harvard Medical School in the US, said: 'We show that hair cells can be regenerated from the surrounding cells in the cochlea.
Before we examine the implications of this promising development, let's look at what is going on deep inside our ears and what role those miniscule hairs play in our hearing. Unlike the hair that grows on our heads, the hair in our inner ears is not visible to a naked eye, but it has a very important function in our ability to hear. Scientists agree that the key to reversing hearing loss - as well as a wide range of diseases that are currently deemed incurable -lies in human stem cells derived from embryos that have been fertilized in vitro and used for research purposes with consent of the donors.
In this country, this issue remains controversial, even though President Obama lifted the longstanding ban on federal funding for embryonic stem cell research. That is just one of several studies carried out in various countries that found that stem cells are instrumental in curing deafness. The latest evidence comes from the Stanford University School of Medicine, where a team of researchers started out with the idea that if they could create hair cells in the laboratory from stem cells, better treatments for deafness and hearing loss would follow. Stefan Heller, PhD, professor of otolaryngology at the Stanford University School of Medicine and a leader in stem cell-based research on the inner ear, found a way to develop mouse cells that look and act just like the animal's inner-ear hair cells.


Eventually, scientists will need human hair cells to experiment on so they can perfect their formula for hair regeneration in the inner ear.
Other studies, conducted over the years by the NIH, also suggest that hair cells could be, contrary to earlier assumptions, regenerated. Admittedly, it is too early to draw any conclusions and it is fair to say that we are still years away from hearing regeneration.
Mice with noise-induced hearing loss generated functioning sensory hair cells after the drug was injected into their damaged cochleas. Located in a portion of the ear's cochlea called the organ of Corti, the sensitive hairs are small sensory cells that process and transmit sound to the brain. Over the course of our lives, these hair cells get damaged and die – for example, because of the aging process, toxic drugs, or prolonged exposure to loud environmental noises- causing varying degrees of irreversible hearing loss. British scientists discovered a way to turn stem cells into ones that act like hair cells, which could be surgically inserted into the ear to restore hearing.
For example, in the 2007 study called "Hair Cell Regeneration and Hearing Loss," the NIH scientists destroyed hair cells in the inner ear of mice, causing deafness.
Again, the supporting cells migrated, but this time partially restored the hearing, indicating that gene therapy could improve hearing in formerly deaf animals. The noises around you were muffled briefly, replaced with a buzzing inside your head, almost as if your ears were screaming.


In fact, according to the National Institutes for Health (NIH), more than 90 percent of hearing loss is due to destruction of hair cells or auditory nerve cells.
In fact, further tests show that mice cells responded to vibrations in a similar way to hair cells in the (human) inner ear. However, the mice's supporting cells spontaneously "migrated to the hair cell region and began growing hair bundles on their surfaces," the researchers reported.
In a way, they were.­Noise levels louder than a shouting match can damage parts of our inner ears called hair cells. Without hair cells, there is nothing for the sound to bounce off, like trying to make your voice echo in the desert.Hair cells reside in the inner ear inside the shell-shaped cochlea.
When sound waves travel through the ears and reach the hair cells, the vibrations deflect off the stereocilia, causing them to move according to the force and pitch of the vibration. This motion triggers an electrochemical current that sends the information from the sound waves through the auditory nerves to the brain.­When you hear exceptionally loud noises, your stereocilia become damaged and mistakenly keep sending sound information to the auditory nerve cells.
