Cryopreservation of hepatocytes as monolayers circumvents the problems of low post-thaw recovery and attachment in culture obtained with hepatocytes frozen in suspension. We have shown that cytochrome P450 dependent generation of reactive metabolites takes place readily in these cells (Stevenson et al., 2004), and in the present study the reduced glutathione (GSH) levels and the expression of the catalytic subunit of glutamate cysteine ligase (GCL) and of glutathione synthetase (GSS) have been investigated.
