Successfully cultured auditory neurons

Scientists from Kyoto University (Japan) have successfully cultivated original auditory neurons based on the use of multifunctional stem cells (iPS) from rat skin.

This result is beneficial for the treatment of people with hearing loss due to the reduction of the number of hearing nerves caused.

Professor Ito Shoua and Shinya Yamanaka of Kyoto University led the research team that carried out the cultivation of iPS-based original auditory neurons made from mouse skin cells.

Later, the scientists implanted this original auditory nerve cell into the cochlea of ​​newborn newborn mice.

After 1 month, most of the implanted cells developed very quickly and formed cochlear nerves - a type of nerve that would cause hearing loss if they were minimized or lost.

Previously, the team successfully cultivated the original auditory neuron based on the use of embryonic stem cells, then implanted in the hearing-impaired mice and partially improved hearing of the mouse.

The cultivation of iPS-based original auditory neurons can help avoid the problem of elimination.

Therefore, Japanese scientists believe that the above results are beneficial for treating people with hearing loss due to the reduction of the number of hearing nerves caused.

In addition, the experiment also demonstrated that iPS cells have different origins and are capable of producing cancer cells, so in the next study, the scientists will choose iPS cells suitable for Performing accurate and effective transplantation of original neurons./.
