Caption Gt(ROSA)26Sortm1(tTA,tetO-Mir155)Fjsl/Gt(ROSA)26Sor+ Tg(Nes-cre)1Wmz/0 (mir-155LSLtTA) mice develop disseminated lymphoma. (A) Mutant mouse with ruffled fur and massively enlarged peripheral and axillary lymph nodes (arrowheads) (n=20). (C, D) Representative H&E sections from wild-type mice reveal distinct periarteriolar lymphocyte sheaths (PALS) in spleen and normal cortex and medullary in thymus; (n=20). (E, F) Representative H&E sections from mutant mouse spleen and thymus. Spleen and thymic parenchyma are effaced and replaced by a monotonous population of lymphoblasts (n=20). (G-J) Lymphocyte infiltration into liver, submandibular lymph nodes (SMLN), meninges of the brain (I, asterisk), paravertebral lymph nodes (J, arrows), and meninges of the spinal cord (J, arrowhead). Scale bars, 500 um (n=20).
