Hi @hgregory, welcome to Connect.
You'll notice that I moved your message to this existing discussion about stem cell research and lung diseases in the Lung Health group. I recommend reading through the past messages in this discussion as well as these:

– Stem Cells / Regeneration https://connect.mayoclinic.org/discussion/stem-cells-regeneration/

Regenerative medicine for COPD is still in the research phase. Do use caution about promises made by some clinics.

To help people learn more about the proven therapies and the promise of developing therapies, Mayo Clinic offers a free telephone consult service. When you call the consult service, they will tell you about the availability of approved stem cell therapy at Mayo Clinic and elsewhere, and for what conditions. You can learn more about the Consult Service here http://www.mayo.edu/research/centers-programs/center-regenerative-medicine/patient-care/clinical-services/regenerative-medicine-consult-service.
Or call 1-844-276-2003 to speak with one of our experts.

You may also be interested in the discussions in the Neuropathy group https://connect.mayoclinic.org/group/neuropathy/ in particular this discussion:
