Abstract
Summary Using the system of morphometric analysis described in this paper, human peripheral blood T and B lymphocytes, labeled with specific surface markers, can be compared on different analytical levels. They show differences in their surface and the eccentricity of cells, in the relative surfaces occupied by peripheral and central condensed chromatin, in the average surface of the central chromatin clumps and in the number of perichromatin granules per nuclear surface. The morphometric analysis reveals the importance of examining the nuclear and the surface parameters in the characterization of lymphocytes, confirming that a detailed analysis of the nuclear characteristics can contribute to the identification of T and B lymphocytes by transmission electron microscopy.
