S-100 protein-immunoreactive cells in the lymph node and spleen of the rat.

The present study deals with an immunocytochemical localization of S-100 protein in the rat lymph nodes and spleen. The immunoreactivity for S-100 was contained in the reticular cells within the germinal center. The immunoreactive cells possessed a scanty perinuclear cytoplasm and extended slender cytoplasmic processes among lymphocytes. No cell outside the… CONTINUE READING
