This protocol describes decellularization of Sprague Dawley rat kidneys by antegrade perfusion of detergents through the vasculature, producing acellular renal extracellular matrices that serve as templates for repopulation with human renal epithelial cells. Recellularization and use of the resazurin perfusion assay to monitor growth is performed within specially-designed perfusion bioreactors.
We describe simple methods to study the regulation of intestinal serotonin transporter (SERT) function and expression using an in vitro cell culture model of Caco-2 cells grown in 3D and an ex vivo model of mouse intestines. These methods are applicable to the study of other epithelial transporters.
This protocol describes asynchronous mixing of human embryonic stem cells derived kidney progenitors at the air-liquid interface to efficiently generate kidney organoids.
