Building on earlier work, Dekkers et al. describe the first application of their intestinal organoid culture technology to the study of human disease, in this case cystic fibrosis. These so called 'mini-guts', which recapitulate the essential in vivo intestinal tissue architecture in vitro, are used to develop a rapid and quantitative assay to measure mutant cystic fibrosis transmembrane conductance regulator (CFTR) function, as well as test the efficacy of correctors and potentiators of mutant CFTR.
