The epidermal differentiation complex (EDC) is a gene complex comprising over fifty genes encoding proteins involved in the terminal differentiation and cornification of keratinocytes, the primary cell type of the epidermis. In humans, the complex is located on a 1.9 Mbp stretch within chromosome 1q21.
Those stem cells and their differentiated progeny are organized into columns named epidermal proliferation units. [ 5 ] During this differentiation process, keratinocytes permanently withdraw from the cell cycle , initiate expression of epidermal differentiation markers, and move suprabasally as they become part of the stratum spinosum ...
