“…therefore it is necessary to create, choose and use models which are as simple as possible, yet as complex as necessary, to address a certain question (Hartung, 2007;Hartung et al, 2004Hartung et al, , 2013leist et al, 2010. to that end, a call for data-sharing (Breeze et al, 2012;Hanson et al, 2011;Murray-Rust et al, 2010) and incorporation of bioinformatics approaches and other new and useful technologies for data mining and interpretation (Blaauboer et al, 2012;leist et al, 2012b) is deemed vital to the future of organotypic models in toxicological investigations. the participants in the 3D modelling symposium included these and a number of other recommendations as important for improving the quality and utility of organotypic models and increasing the probability of regulatory acceptance as a replacement for in vivo testing.…”
