P, This past February I had treatment with stem cells from a stem cell bank in Baltimore, MD. the cost was just under $9,000. I don't know if my condition has improved or not as I have no reference to what my condition would have been had I not had this therapy. I go to my pulmonologist later this month and have some testing done to see how much my condition has changed in the past 6 months or so. I doubt this will help you much but I did want to chime in and let you know that you are not alone fighting this condition.
If you want to stay in touch we can do that in format.
