HEALTH - There is good news for those who have been deaf since birth. Some researchers claim to have found a way to replace cells of the cochlea (the cochlea) is damaged since birth because of genetic errors.
It is expected that new findings can be used at this stage of treatment in 5 to 10 years. Thus reportedly page Express, Sunday (11/20/2016).
"I am very happy with what we have done." said Professor Kazusaku Kamiya, ear diseases specialist and leader of the research results have been published in the journal Stem Cell Report.
"We hope this research will be able to produce a drug for patients with hereditary deafness disease. The next step is to find a way to inject the stem cells safely into the patient's ear."
Research conducted in the laboratory in Jutendo University, Tokyo, Japan, is intended to correct mutations in a gene called Gap Junction Beta 2, which lead to deafness or hearing loss.
In some parts of the world, the mutation of the cells of the cochlea responsible for nearly half the cases of genetic or hereditary deafness.
Professor Kamiya and his team had been using and cultivating stem cells to replace the cells of the cochlea without these mutations.
Stem cells, or stem cells, are the basic types of cells that can turn into other types of specialized cells such as muscle cells or cells of the cochlea through a process known as differentiation.
Working system stem cells with age. Increasingly hosting someone, especially after reaching the age of 40 years, stem cells function less and less effective. That's why injuries in young children heal faster than the wounds in adults.
Derivative hearing loss is often caused by genetic mutations in the ear hair cells, which are found in the inner ear, or cochlea, sound sensors and receptors.
Patients with this condition will be treated with an artificial cochlear implants can help transfer sound to the auditory nerve impaired patients.
Many scientists believe stem cells may offer a better solution to restore the normal function of the hair cells and the results patients can hear again.
Humans are born with about 11,000 hair cells in each ear has a very important function in the transmit sound.
Aging makes these cells also work more slowly. Another thing that affects the use of drugs is excessive.
For the moment there is not a perfect treatment that is able to cope with hearing loss, as quoted by the Daily Mail (21/11).
A new study was also conducted by a team led by Sarah Boddy of the University of Sheffield. He is investigating the potential of stem cells in human bone marrow to restore hearing.
Tim Boddy showed that human bone marrow stem cells can be converted to the ears.
