title: Morphology of lymphoreticular tissues in mice with reticulosarcoma.
abstract: The response of murine lymphoreticular tissues to transplantation of a syngenic reticulosarcoma with mild transplantation antigenicity was studied by recording weight changes and histology. The results were compared with those obtained in normal mice and mice challenged with syngenic spleen cells. The tumor induced vigorous histological response in regional lymph nodes and mild response in nonregional lymph nodes and spleen. Mesenteric lymph nodes and thymus did not respond to the tumor. Observed morphological and gravimetrical changes indicated that both regional and nonregional lymph nodes and spleen take part in host immune response to tumor. A possible contamination of tumor tissue by viruses has been excluded.
