Stem cells are being looked at for dorsal root damage that fails to self repair due to a genetic defect. Seems autologous cells would have the same defect? I don't know the details about stem cells.

Our MG board has a member who had the bone marrow reboot.
And this topic gets some discussion on our MS forum now and then.

There are several types of PN that may respond, but they are all slightly different. So how the stem cells would be applied --where they would be injected-- seems a big factor.

Somewhere here on the board I have a paper I linked to about stem cells for PN....

I am looking now for that paper... found this along the way:

This is interesting.

I can't find the specific article right now... but it involved stem cells as a proposed treatment for dorsal root damage,that the patient cannot repair themselves due to genetic reasons for a lack of a specific enzyme.

Stem cell research seems to have alot of ups and downs, with many failures. So I don't think it has reached a level for general applications for patients, yet.
