摘要
The aim of the study was to review literature data on cell models for experimental assessment of drug nephrotoxicity in vitro. Because of nephrotoxicity, 2% of new investigational medicinal products are discarded at the stage of preclinical in vivo studies in laboratory animals, and 19%—after phase 3 clinical trials. Prediction of toxicity in cell models could make drug development more cost-effective and help to reduce/avoid animal testing. At present, there are no official international guidelines for assessment of nephrotoxicity in vitro, but there is a lot of research underway. The main toxicity target in kidneys is renal proximal tubule epithelial cells, therefore the main research is focused on the development of renal proximal tubule epithelial cell lines with stable functional characteristics. Another important aspect in nephrotoxicity modeling is the choice of relevant test methods and end points which would reflect potential toxicity mechanisms. The paper reviews existing human renal proximal tubule epithelial cell lines and current test methods for assessing cytotoxicity. Promising areas for future development of cell models for nephrotoxicity assessment— are optimisation and standardisation of in vitro systems that would help to make preclinical predictions of drug nephrotoxicity in vivo.
