Abstract

Merkel cells (MCs) constitute a very unique population of postmitotic cells scattered along the dermo-epidermal junction. These cells that have synaptic contacts with somatosensory afferents are regarded to have a pivotal role in sensory discernment. Several concerns exist till date as to their origin, multiplication, and relevance in skin biology. The article, a collective review of literature extracted from PubMed search and dermatology books, provides novel insights into the physiology of MCs and their recent advances.

Keywords: Epidermis/embryology; Merkel cell; epidermis/ultrastructure; human skin; keratins; mechanoreceptors; mucosa; nerve endings/ultrastructure.
