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.
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.
