Liver transplantation is recommended for patients with liver failure, but liver donors are limited. This necessitates the development of artificial livers, and hepatocytes are necessary to develop such artificial livers. Although induced hepatocyte-like cells are used in artificial livers, the characteristics of mouse induced hepatocyte-like cells (miHeps) reprogrammed with embryonic fibroblasts have not yet been clarified. Therefore, this study investigated the mechanisms underlying the survival, function, and death of miHeps. miHeps showed decreased cell viability, increased cytotoxicity, decreased hepatic function, and albumin and urea secretion at passage 14. Addition of necrostatin-1 (NEC-1) to miHeps inhibited necrosome formation and reactive oxygen species generation and increased cell survival. However, NEC-1 did not affect the hepatic function of miHeps. These results provide a basis for development of artificial livers using hepatocytes.
