since activation of afb1 is catalyzed by cytochromes p-450 associated with the smooth endoplasmic reticulum , we compared the response to afb1 in cultured tracheal epithelium from species with abundant ( rabbit and hamster ) and scarce ( rat and monkey ) distributions of smooth endoplasmic reticulum in nonciliated tracheal epithelial cells .
