Résumé : The present report constitutes an electron microscope survey of the morphology of the cells of a spontaneous, transplantable carcinoma of the kidney, developed and grown in the BALB/c strain of mice. Two main features appear to be of particular interest: (1) dense nuclear inclusions; and (2) virus-like particles found in constant association with the cytoplasm of the renal tumor cells. © 1962 Academic Press Inc.
