Gastroenterologia 2, IRCCS Ca' Granda, Ospedale Policlinico di Milano We introduce a novel method for the maintenance of human intestinal mucosa in culture and monitoring of the response to various types of stimuli over at least 24 hrs. With our method, the polarity of the tissue is maintained, allowing for a physiological stimulation via the apical route.
