[The ultrastructure of lymph node cells in lymphogranulomatosis]

An electron-microscopic study of lymph node cells in patients with lymphogranulomatosis has shown that the ultrastructure of these cells undergo some changes consisting in increased variability of the form and size of cellular organoids, and also being manifested in reticular cells to a greater degree than in lymphoid ones. A compparative study of cell ultrastructure at different stages of maturation and the analysis of literature data on ultrastructural changes in the process of differentiation of various cell types enabled to pinpoint further a conception of the morphological basis of differentiation at a subcellular level and to represent it schematically.
