Abstract Of late, numerous microphysiological systems have been employed to model the renal proximal tubule. Yet there is lack of research on refining the functions of the proximal tubule epithelial layer—selective filtration and reabsorption. In t

P-glycoprotein (P-gp), one of transporters in the human renal proximal tubule epithelial cells (RPTECs), plays an important role on the excretion of drugs. Therefore, evaluating the transport property of P-gp can help in the development of ideal phar
