Cell transplants may cure deafness

Summary:

When Uppsala researchers found immature stem cells in the inner ear of humans a few years ago, it caused a global sensation. They have also managed to grow hearing nerves from stem cells and human tissue from donated cochleae. Moving images of how nerve cells, like social, swimming beings, seek out each other are now suggesting entirely new and breathtaking perspectives to researchers. The next step will be to study how this growth is affected by electric fields. The researchers want to see, on the one hand, whether electric stimulation can get remaining nerve fibers to grow in hearing impaired individuals and, on the other hand, whether nerves can be made to grow out again after having been damaged or exposed to alcohol and other toxins.
