Hi clee! Since this is such a new treatment option, I am not aware of any members that have tried it as of yet. That doesn't mean they haven't; I am just not aware of them. There has been promising research in regards to stem cell infusions in other conditions, so we'll have to see if this research makes its way to RA! I hope you get some feedback from our members!
