Another approach is to inject genes into the inner ear that are responsible for growing new hair cells. The mouse Math1 gene and its human equivalent, the Hath1 gene have the potential to restore hair cells. However, the only way to deliver these genes has been by attaching them to a virus which, by its nature, inserts itself into the nucleus of a cell and turns that cell into a hair cell.
I wonder the possibilities of 20DB improvements unless there are evidence.
BTW, what is the cost of inject ~20 million stem cells by IV in arm every month.
2 In the moment, there is no evidence that Chole curing involves inner ear hairs.
Well, in case the stem cell therapy no improvements on the hearing, I believe
it brings good effects on your body. If you decide to go for the therapy, I wish you good luck. When you plan to go abroad? Is the clinic locates in China? Please let me know the exact location. If it is near Hong Kong like Guangzhou, I may come to say Hi and buy you a drink.
