Abstract:

Five hundred and two cells, selected by serial focusing on at least one different neoplastic cell within the lymphoma-involved lymph nodes of pre-treatment patients with the nodular sclerosis type of Hodgkin's Disease, were analyzed by electron microscopy for in-vivo intracellular activity and intercellular interaction (J. Natl. Cancer Inst., 63: 331 (1979). Neoplastic cells (no. = 31) represented 5% of the total sampled cell population, whereas lymphocytes (no. = 437) represented 87% of the sampled population. Activation of DNA templates within neoplastic Reed-Sternberg and Hodgkin’s cells and within apposed lymphocytes was recognized by ultrastructural DNase I-sensitive probes (Cancer Res., 31: 1128 (1971). Active lymphocytes were most often found apposed to the more active of the neoplastic cells, and the nuclei of such apposed lymphocytes displayed a progressive preferential uni-polar clustering of active DNA templates into that half of the lymphocyte nucleus closest to the neoplastic cell. Such uni-polar clustering of active DNA templates may reflect spatially-directed intracellular responses to intercellular contacts between activated lymphocytes and their neoplastic cell targets.
