title: The maintenance of cytochrome P-450 in liver cell culture: recent studies on P-450 mediated mechanisms of toxicity.
abstract: Rat hepatocytes have been cultured under conditions that result in low and high cytochrome P-450 concentrations and then used as a "screening test" to determine the involvement of cytochrome P-450 in toxicity. The results show that a limitation to the use of cultured hepatocytes in toxicity tests is the lack of extrahepatic release mechanisms of toxic compounds.
