Dermoepidermal junction
The dermoepidermal junction or dermal-epidermal junction (DEJ) is the area of tissue that joins the epidermal and the dermal layers of the skin.[1] The basal cells in the stratum basale of the epidermis connect to the basement membrane by the anchoring filaments of hemidesmosomes; the cells of the papillary layer of the dermis are attached to the basement membrane by anchoring fibrils, which consist of type VII collagen.[2]
Stevens–Johnson syndrome and toxic epidermal necrolysis are diseases where there is a breakdown of the dermoepidermal junction.
