[The fibrillar centers of cell nucleoli from Ehrlich tumors. New cytochemical ultrastructural studies].
With electron microscopical preferential stainings, we show that the fibrillar centres of Ehrlich tumour cell nucleoli contain small amounts of DNA. These observations confirm our results previously obtained with enzyme digestions and autoradiographic methods. These data agree with our conception according to which the fibrillar centres of Ehrlich tumour cell nucleoli could be the nucleolar organizers.
