Cells in the Lymph Node and Spleen of the Rat
نویسندگان
چکیده
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 germinal center showed any immunoreactivity to the anti-S-100 serum.
