Kidney membrane transporters are key to drug disposition and renal clearance. Primary renal proximal tubule epithelial cells (RPTEC) are the most physiologically relevant cell models, but lose OAT1 and OCT2 expression in culture. Primary RPTEC transiently expressing these transporters show large variations between production lots. Furthermore, cell line-based models either do not have the kidney tissue origination or are tumor-derived. This presentation will introduce transporter cell models using hTERT-immortalized RPTEC that stably overexpress the OAT1 or OCT2 gene. Our data show that these cell lines provide tissue-relevant results, improved consistency over time, and predictability for clinical trials.
