They target many of those and many more and have very succesful Phase 2 trials. In fact I do not believe they have had a single unsuccesful test ever.
Interesting as their product will follow a pharamceutical model - great for sales - but it is infact stem cells. They use some adult stem cells (no ethical issues) and then 'grow' them with a patented method that isolates the MPC type (compatable with anyone) and can grow heaps of them. So they build up a big stock of it and sell/provide it to patients as needed (the pharma model). It really is looking outstanding IMO.
