Collecting-duct-derived renal epithelial cells switch from tubule to cyst formation; however, the cysts still form tubules after injury of the cyst-lining epithelium. Here, we provide a protocol that describes in vitro cyst growth with focus on glass-capillary-induced cyst wall injury to induce tubule formation. We detail steps for the establishment of the in vitro cyst assay, followed by puncture of the cysts in the collagen matrix. We further describe live imaging and steps to analyze the tubule growth. For complete details on the use and execution of this protocol, please refer to Scholz et al. (2022)..
