According to the scientists they have discovered the method to convert the stem cells into sensory, more precisely, auditory neurons that can be inserted with operation to restore hearing in deaf people.

The technique that has proven effective in the animals still is not in the position to serve humans.

“It may take some years, before we implement this on the human body,” lead researcher Marcelo Rivolta said. The sound detector cells of the ear only develop in the metamorphosis of the child and there is no way to repair them if damaged, which may result in partial or complete hearing loss.

Beside this study, researchers are also trying to treat age related eye disease such as macular degeneration or cataract etc with stem cells which have the potential to produce any type of body tissues and organs.

Researchers hope that one day they would be able to treat deadly diseases like cancer, diabetes or Parkinson’s disease with the help of stem cells. The initial step from ears or eyes may become a ray of light, since there is involvement of few cells.
