Summary
Primary cultures of rat hepatocytes survived well for up to 4 days in defined medium in the presence of dexamethasone but not in its absence. The loss of viability was accompanied by a loss of ultrastructural features characteristic of hepatocytes. The cultures began producing plasminogen activator and a neutral protease after 24 hr in culture. Dexamethasone inhibited the production of both of these substances. The deterioration of the cultures appeared not to be related to plasminogen activator, but prolongation of survival by a variety of protease inhibitors suggested that the neutral protease might contribute to deterioration.
