title: Morphological alterations induced in organ cultures of human fetal trachea and bronchi by diethylnitrosamine (DEN).
abstract: Human fetal respiratory tract was exposed to the action of N-nitrosodiethyl-amine (DEN), a potent carcinogen for other species, in a organ culture system. The dose of 15 mul/ml DEN elicited an intensive proliferative response of the respiratory epithelium while higher doses were toxic.
