Abstract:

Isolated trout hepatocytes were frozen using a programmable freezer and stored in liquid nitrogen. Satisfactory viability were obtained in cryopreserved hepatocytes (CP) as judged by trypan blue exclusion (TB). The viability of primary cultures of CP hepatocytes, was compared with fresh cells using attachment efficiency (using TB), the rate of neutral red uptake (NRU), metabolism of the tetrazolium salt (MTT), and measurement of intracellular lactate dehydrogenase content (LDH). These results show that the activities of CP cells was lower than in fresh cultures, but remained constant over 72 hr of culture (~70%). The CP cultures retain the aspects of liver-specific function as shown by the induction of cytochrome P-4501A1 (CYP1A1) by 3-methylcholantrene (3-MC) and Benzo[a]pyrene (B[a]P) exposure.
