Background: Renal ischemia/reperfusion injury (rIRI) is one of the major causes of acute kidney injury (AKI). While animal models are suitable for investigating systemic symptoms of AKI they are limited in translatability. Human in vitro models are crucial in giving mechanistic insights into rIRI, however, they miss out on crucial aspects as reperfusion injury and the multi tissue aspect of AKI. Methods: We advanced the current renal proximal tubule-on-a-chip model to a coculture model with a perfused endothelial vessel separated by an extracellular matrix (ECM). The coculture was characterized for its three-dimensional structure, protein expression, and response to nephrotoxins. Then, rIRI was captured through control of oxygen levels, nutrient availability, and perfusion flow settings. Injury was quantified through morphological assessment, caspase 3/7 activation, and cell viability. Results: The combination of low oxygen, reduced glucose, and interrupted flow was potent to disturb the proximal tubules. This effect was strongly amplified upon reperfusion. Endothelial vessels were less sensitive to the ischemia-reperfusion parameters. Adenosine treatment showed a protective effect on the disruption of the epithelium and on the caspase 3/7 activation. Conclusions: A human in vitro rIRI model was developed using a coculture of a proximal tubule and blood vessel on-a-chip, which was used to characterize the renoprotective effect of adenosine. The robustness of the model and assays in combination with the throughput of the platform make it ideal to advance pathophysiological research and enable the development of novel therapeutic modalities.
