[Morphological and cytochemical investigation of Ehrlich ascites tumor cells of the solid form as compared with peritoneal exudate in mice (author's transl)].

Ehrlich ascites tumor cells in peritoneal exudate of mice show a more regular round shape, greater and multiple nucleoli and more abundant and dark cytoplasma in comparison with cells of the same tumor transplanted in the limb. In solid tumor cells activity of naphthol-AS-acetate esterase is significantly higher than in exudate cells which demonstrate higher activity of PAS reaction. Other cytochemical reactions show no significant differences between the two cell forms. It seems that exudate cells are biologically more active than cells from the solid tumor.
