Cornification is the process of forming an epidermal barrier in stratified squamous epithelial tissue.
At cellular level cornification is characterised by
* production of
* production of small proline-rich (SPRR) proteins and
transglutaminasewhich eventually form a cornified cell envelope beneath the plasma membrane
* terminal differentiation
* loss of nuclei and organelles, in the final stages of cornification metabolism ceases and the cells are completely filled by keratin
