Histopathological characterization of a syngeneic orthotopic murine bladder cancer model

Abstract

High tumor take rates were achieved by using the chemical induction of the bladder tumor. Although electric cauterization is widely described in the literature for syngeneic orthotopic animal models, the technique described in this study represents an alternative for intravesical bladder tumor implantation. Moreover, the histopathology and immunohistochemical analysis of the murine bladder tumor model derived from the MB49 cell line showed a resemblance to human infiltrating urothelial carcinoma, allowing clinical inference from experimental immunotherapy testing.
