I just want to inform everyone that I have not received any reply from Dr. Rivolta. I sent him the e-mail on 15 June. It's 7 July now. I no longer expect to get any reply from him. I will post back if I do.
No reply from him, if that's what you mean. I can't say I have been following his work closely either. I am not rooting for a cell based therapy to be honest. In-body progenitor cell activation using drug therapy is what I believe in, if we are talking about hair cell and neural cell regeneration. Purely for treating tinnitus, I believe in different forms of neuromodulation, including the somato-auditory stimulation being tested at university of Michigan and university of Minnesota. But hey what do I know what works and what doesn't? I am just a happy amateur. Just giving you my 50 cents.
