[Morphometric analysis of the ultrastructure of tumor cells with a varying protein synthesis specificity].

The author has studied morphometrically the cell ultrastructure of fibroblastic and smooth muscle human tumors. There were found some differences in the quantitative features of the energetic (mitochondria) and protein-synthesizing (ergastoplasm and polyribosomes) cellular apparatus of these neoplasms. The specific criteria of the malignancy grade were identified for both groups of tumors.
