Peripheral neuropathy is characterized by numbness, tingling, and/or pain, typically in the hands and feet, although these symptoms can occur in other areas of the body. There can be numerous causes of a peripheral neuropathy. Diabetes is perhaps the most common cause, although other causes can include trauma, infections, and nutrient deficiencies. And this is yet another problem which does seem to be more common in people with thyroid and autoimmune thyroid conditions.
Once transplanted, the stem cells spontaneously grew into hair follicles that produced hair in the mice. Researchers say they also identified a set of genes that are turned on by the stem cells, which may provide new targets for manipulating hair growth.
Researchers have long suspected that stem cells located within the follicle bulge were responsible for hair growth. Because of their quiescent nature and strategic location, bulge cells were postulated to be hair follicle stem cells in both mice and men.
