Abstract | Primary human hepatocytes are an essential in vitro tool for evaluating drug metabolism, drug-drug interactions, and hepatotoxicity. This model is considered as the gold standard in matter of DMPK studies in both industrial and academic research. The primary human hepatocytes are used either in suspension or in monolayer, as fresh or frozen cells. However, the use of this model is limited due to the lack of availability, rapid loss of functionality, high cost as well as the variable hepatocyte plating efficiencies in culture and the limited stock of hepatocytes derived from the same origin. Chimeric TK-NOG mice with humanized livers (humanized liver mice) are an attractive platform for drug metabolism and toxicity, which were produced by transplanting human hepatocytes into immunodeficient mice with injured livers. Here, we show that, using humanized mouse liver, in vivo human hepatocyte repopulation was over ~100-fold enabling the continuous and abundant use of human hepatocytes of the same origin and improving their plateability. In our latest cell preparations, hepatocytes isolated from humanized liver mice (Hu-Liver cells) exhibited high purity (ratio of HLA-positive cells: 92±3%), good viability (75±12%), and yield (1.0×10 |
