Cell Type Overview
In the kidney's collecting duct, principal cells are the most abundant cell type. They are responsible for the final regulation of water, sodium, and potassium balance. They express aquaporin-2 channels on their apical membrane (inserted in response to vasopressin/ADH) for water reabsorption. They also reabsorb sodium via ENaC channels and secrete potassium, processes regulated by aldosterone.
