Liver Engineering Laboratory

Liver Engineering Laboratory has been creating a new humanized animal model by modification of NOG mice, especially focusing on development of a liver-humanized model. We established TK-NOG strain which is a drug-induced liver failure model. The expression unit of herpes simplex virus thymidine kinase was introduced to NOG mouse by using microinjection technique. The TK-NOG mice can bear human hepatocytes at high rates on the basis of extremely high acceptability of xenogeneic cells. We succeeded to replace the mouse liver nearly 80% with human hepatocytes. The "humanized liver" reconstructed with human hepatocytes has been shown to have drug metabolizing properties similar to those of the human liver. In addition, we further improve the NOG mouse by using a microsatellite marker assisted selection protocol (known as speed congenic) to efficiently replace the genetic background of conventional transgenic mouse and knockout mouse to that of NOG strain (super immunnodeficient) while preserving the characteristics.
