I think even Mayo would say that stem cell research is very experimental. It has been practiced in other countries for years, with no documented dbl blind studies. So beware, 10s of thousands of dollars can easily be spent on experimental therapies, but none have been shown to change the outcome for people with MSA.
Also (you didn’t ask) it is very unusual for someone with MSA to be diagnosed with MSA at 31. Do you have a second opinion from some who has experience diagnosing and treating this rare disorder?
