I've seen suggestions in the medical literature that exosomes, which are little vesicles spontaneously generated from stem cells, show promise for treatment of neuropathy and present less risk than stem cells. They supposedly contain a variety of growth factors, and anti-inflammatory compounds that enhance regrowth of axons and myelin sheath, and modulate the inflammatory attacks that cause the pain. Much of the research is done in China - not seeing a lot in the U.S. Has anyone had any experience with this therapy?
