Development of new anti-fibrosis therapies is a highly inefficient process, as no existing in vitro models can accurately recapitulate the dynamic patho-physiological changes in tissue mechanics during fibrogenesis. In this study, we created novel micropillar microdevices, which allow thin and membranous fibroblast microtissues to be formed, similar to the morphology of lung alveolar tissue.
