The gastrointestinal (GI) tract is an important target organ for the toxicity of xenobiotics. The toxic effects of xenobiotics on this complex, heterogeneous structure have been difficult to model in vitro and have traditionally been assessed in vivo. The explant culture of GI tissue offers an alternative approach. Historically, the organotypic culture of the GI tract proved far more challenging than the culture of other tissues, and it was not until the late 1960s that Browning and Trier described the means by which intestinal tissues could be successfully cultured. This breakthrough provided a tool researchers could utilise, and adapt, to investigate topics such as the pathogenesis of inflammatory intestinal diseases, the effect of growth factors and cytokines on intestinal proliferation and differentiation, and the testing of novel xenobiotics for efficacy and safety. This review considers that intestinal explant culture shows much potential for the application of a relatively under-used procedure in future biomedical research. Furthermore, there appear to be many instances where the technique may provide experimental solutions where both cell culture and in vivo models have been unable to deliver conclusive and convincing findings.
