An Ex Vivo Gut Organ Culture System to Study Host-Microbiota Interactions

Published: September 29, 2023

Abstract

Source: Azriel, S., et al. An Intestinal Gut Organ Culture System for Analyzing Host-Microbiota Interactions. J. Vis. Exp. (2021).

In this video, we describe the methodology for setting up an ex vivo gut organ culture system to study the interactions between mouse intestinal tissue fragments and specific gut bacteria. The device consists of two pairs of input-output ports, the first connecting the intestinal tissue lumen and supplying the specific bacterial suspension into it, and the second continuously supplying media to the device's wells to maintain ex vivo tissue viability.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Experiment preparation Fabrication of the gut organ culture device (3 days) Using a 3D printer, print the reusable plastic molds for the organ culture device (the device has 6 wells, with 24 small and large holes, and for the device cover lid). NOTE: These plastic molds may be used f…
