There are companies performing autologous stem cell transplantation on an outpatient basis. The procedure is indicated for several conditions: Alzheimer's, Parkinson's, MS, Autoimmune PN, Type II Diabetes and more. The procedure involves harvesting a patient's own stem cells extracted from the abdomen (mini-liposuction procedure), laser application and systemic reintroduction. That's my understanding of the procedure anyway.

It is the Autoimmune PN indication that got my attention but I could not locate supporting data so I contacted one of the companies and they said the PN improvement has been when it is a secondary condition and that the results are very good. I was intrigued by this since those of us with IPN do not know what our primary condition is (although some of these unknown cases are probably autoimmune related) however I am unable to locate the data which likely means it does not exist. I thought to check here with others first before dismissing it .
