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 generally grows an average of 1/2 inch per month, with growth generally predetermined by a person's genetic code, meaning that it can only grow so fast. In a year, hair usually grows about 6 inches. As a person ages, hair growth can slow due to cell division also slowing. Hair growth is a result of cell division when new hair cells form in the root and push the hair forward. The new hair is always added at the root as the older hair inches downward slowly.
