Engineering kidney tissues for polycystic kidney disease modeling and drug discovery

Abstract

Autosomal dominant polycystic kidney disease (ADPKD) is the most prevalent, potentially lethal monogenic human disorder. There is currently no cure for ADPKD. The mechanistic complexity of the disease, the absence of animal models that can faithfully mimic the disease, as well as the lack of functional human in vitro assays for compound testing, have made drug discovery for PKD very difficult. We recently developed an engineering platform that allowed us to generate polycystic tubules using patients' own cells to test drug efficacy and discover potential new pharmacological treatments for PKD. Here we describe an engineering platform that enables the generation of custom-made polycystic tubules using patients' own cells for modeling PKD and testing drug efficacy.
