Comparisons were made of attachment and viability of rainbow trout (Salmo gairdneri) hepatocytes in short-term (2 days), primary culture on plastic, collagen-coated or extracellular matrix (ECM) coated dishes. Hepatocyte isolation routinely yielded cells with good viability (96%). Cells plated on ECM attached with high efficiency (93%) in contrast to cells cultured on plastic or collagen (∼20%). The cells plated on ECM flattened out and formed monolayers, while the cells on plastic and collagen rounded up and formed multi-cell aggregates in suspension. Viability of cells in all substrates remained high over the 2 day culture period. ECM is the first substrate to support trout-hepatocyte attachment in primary culture. Differentiated liver function was maintained in cells cultured on ECM as evidence by the induction of tyrosine aminotransferase by hydrocortisone (200%).
