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.
1 Melanocyte stem cells are responsible for regeneration of melanocytes, a type of pigment cell. 2  Melanocytes produce the pigment melanin, and therefore play an important role in skin and hair follicle pigmentation. 3  It is not yet certain where these stem cells are found in humans. These stem cells are found in the basal layer of the epidermis. 2  Hair follicle stem cells ensure constant renewal of the hair follicles. 3  They can also regenerate the epidermis and sebaceous glands if these tissues are damaged. 4  Hair follicle stem cells are found throughout the hair follicles.
