Abstract
E' descritta una biostruttura comprendente:- un mezzo di supporto di forma sostanzialmente tubolare, di materiale inerte, flessibile, non tossico, non substrato per l'adesione e l'attecchimento di cellule o tessuti;- un epitelio coltivato in vitro di lunghezza uguale o maggiore alla lunghezza di detto mezzo di supporto, avvolto a spirale su detto mezzo di supporto in modo che la superficie basale di detto epitelio sia rivolta verso l'esterno e la superficie apicale di detto epitelio sia rivolta verso detto supporto.
