The proximal tubule, a part of the kidney nephron (the functional unit of the kidney), has highly specialized properties to do with the salvage and excretion of various compounds, salts and minerals that are very important to the body and would otherwise be lost in the urine. In addition, the proximal tubule is essential for the handling of many drugs and so-called xenobiotics that come from outside the body and from the environment (e.g., many artificial substances, including potential toxins). However, there are no good human models in vitro that can recapitulate and reproduce the function of the proximal tubule. A robust model for the proximal tubule is needed, especially since the proximal tubule has an essential role in drug clearance, because it is highly susceptible to damage in many kidney diseases, and it is also a target for drug-drug interactions and drug toxicity. Development of a proximal tubule model system in vitro could help to address some of the gaps in laboratory models for the study of kidney disease, toxicity, and drug handling.
AstraZeneca is seeking innovative approaches to developing a model system of the proximal tubule in vitro. Ideally, the model should incorporate a self-contained microphysiological unit in which biologically appropriate media, fluid flow, and shear stress can be modulated to reproduce the properties of the proximal tubule in vivo and ultimately recapitulate the structural and cellular conditions necessary for integrated proximal tubular function.
This is an ideation challenge and only requires a written solution.
