Abstract:

We have studied the distribution of some cytokeratins in the epithelial cells in some parts of the digestive systems in three lower vertebrate species: Scyliorhinus canicula (Chondrichthyes ), Sparus aurata (Osteichthyes ) ,and Salamandra salamandra (Amphibia). The aim was to compare the evolution of animal tissues by the presence/absence and distribution extent of the cytokeratins. We have used three types of cytokeratins: cocktail, 7, 20.
The result was positive with cytokeratin cocktail in all studied parts of the three species. This emphasizes the presence of cytokeratin in the digestive epithelium of lower vertebrates.

Keywords:
