Tumors developed at 59% (16\/27) of inoculation sites: nine (33%) were neoplastic and seven (26%) were inflammatory. Procedure I achieved 100% neoplastic tumors and produced both non-muscle invasive (71%) and muscle-invasive (29%) tumors. Procedure II achieved 50% neoplastic tumors, all of which were muscle invasive (100%). Procedure III generated only inflammatory tumors. Histologically, neoplastic tumors were pathologically interpreted as urothelial cell carcinomas with sarcomatoid differentiation, with IHC confirming the presence of both epithelioid and sarcomatoid features with abundant mixed leukocytic infiltrates. Genomic analyses verified Cre-induced alterations alongside other mutations seen in human BC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>We herein demonstrate an efficient and reproducible method for developing autochthonous neoplastic bladder tumors in Oncopigs that resemble human bladder cancer of varying stages.
