Bioengineered 3D kidney tissues that emulate human responses could potentially lead a revolution in drug safety testing and ultimately solve organ donor shortage issues. Unfortunately, current kidney-on-chip models lack the 3D geometry, complexity, and functionality necessary to recapitulate in vivo renal tissue. In this talk, I will discuss how we address these engineering challenges by creating 3D vascularized kidney tubule models via multimaterial bioprinting and characterizing their reabsorption properties. In particular, I will discuss how we engineer the flow property and biocompatibility of different soft materials to construct adjacent conduits that are lined with confluent epithelium and endothelium embedded in a permeable extracellular matrix. This 3D kidney model closely mimics the native microenvironment, and thus exhibits superior cell behavior with active reabsorption of solutes including albumin uptake and glucose. Lastly, I will show a few examples of how our model enables toxicity studies and disease modeling that have been difficult to conduct using conventional in vitro systems
