Thank you for your question, Kent59! The use of stem cell in treating COPD is still a growing area of research in the medical community. At this time there is no approved stem cell treatment, though clinical trials do exist. To find out if there are any trials being conducted in your area, I would encourage you to speak with your doctor and/or contact your nearest medical research hospital as they would likely be able to direct you to possible studies and help evaluate if you would be a good candidate. ~Allyson (COPD.net team)
