Description

Touch cells – large oval cells found in the skin and some parts of the mucosa of all vertebrates. They are responsible for the highly malignant skin tumor known as Merkel's cell carcinoma. Most often they are associated with sensory nerve endings, when they are known as Merkel's nerve nedings. They were given the eponymic name Merkel cells in 1878 by Robert Bonnet (1851–1921).

The mammalian Merkel cell is in the epidermis of vertebrates, while Grandry's corpuscles occur only in waterfowl and are located in the dermis of the bill.
