Abstract
We compared the effects of two different systems of collagen matrix protein application on the survival and the biological functions of cultured primary hepatocytes. The rat liver primary hepatocytes were grown for approximately 40 days in vitro either on single collagen gel or between collagen sandwich gels. The morphological changes were observed for this culture period. While the hepatocytes grown on single gel began to die around at 7 days of culture, the cells grown between collagen gels still maintained their viability and began to die after 15 days. As markers for liver hepatic functions, we determined the biochemical activities of hepatocytes such as the secretions of albumin, fibronectin, fibrinogen, urea, and the reduction of secreted ammonia. We found that the rat hepatocytes cultured between collagen gels maintained fairly good biochemical functions than the hepatocytes cultured on single gel did. Therefore, the application of an extracellular matrix protein, collagen, in sandwich form was confirmed as a better choice for maintaining the functional hepatocytes culture for long term in vitro
