Regenerating epithelial tissue from the cockroach leg forms two cuticular coverings. The first of these consists of a protein-carbohydrate complex that is replaced before molting. The second covering represents the cuticle containing chitin. The deposition of the cuticle can be induced in vitro by adding ecdysterone to the culture medium.
