X-Ray & Tomography

Human Epidermal Melanocytes-dark (HEM) is a neural crest-derived cell that localizes in humans to several organs including the epidermis, eye, inner ear and leptomeninges. The failure of melanocytes to migrate to these locations explains the association of congenital white spotting of the skin (piebaldism) with heterochromia (the juxtaposition of different colors) in the iris as well as congenital deafness in Waardenburg syndrome.
