Number of nucleoli in Ehrlich tumor cells during interphase.
Fractions of mouse Ehrlich ascites tumor cell populations with a high percentage of cell either in early or in late interphase were separated by centrifugation on ficoll gradients. Nucleoli were studied by light or electron microscopy in these cell subpopulations. It was shown that, in these cells, the number of nucleoli per nucleus does not vary significantly during interphase. This result is discussed and an anlysis of the relationships between the number and the volume of the nucleoli in these cells is present.
