Experimental cerebral tumors have been induced by transplacental ENU. A systematic diachronic study of the brains has been performed starting from the 15th day of extrauterine life. The tumoral lesions firstly appear as 'early stage proliferations' or oligodendroglial foci and develop as glial micro- and macrotumors or as isomorphic and polymorphic oligodendrogliomas respectively. Neurinomas appear later than glial tumors. The duration of the different lesions is sketched out. The usefulness of the model for chemotherapy studies is discussed.

Abstract
Experimental cerebral tumors have been induced by transplacental ENU. A systematic diachronic study of the brains has been performed starting from the 15th day of extrauterine life. The tumoral lesions firstly appear as 'early stage proliferations' or oligodendroglial foci and develop as glial micro- and macrotumors or as isomorphic and polymorphic oligodendrogliomas respectively. Neurinomas appear later than glial tumors. The duration of the different lesions is sketched out. The usefulness of the model for chemotherapy studies is discussed.
