Its already being used as a stroke treatment in a Florida clinic and the medical trials seem promising. Thanks for the link to the trial. I emailed the USA clinic and received a very quick return call, with an offer of a $USD 500 phone consultation. Think I will cool my heels and do more research first as the treatment is about $USD7000 per injection, plus travel and accomodation. The side effects include immune suppression. Any one else know anything?
