Orthotopic transplantation of Kras and Kras;p53-flox tumor cells recapitulates the primary tumor phenotype.
(A) Cartoon of the transplantation scheme used to assay lung tumor-propagating cells (TPCs) through serial transplantation. (B) H&E staining of primary (left) and secondary (right) Kras lung adenocarcinomas showing similar pathological grade, nuclear features, and general tumor architecture. (C) H&E staining of primary (left) and secondary (right) Kras;p53-flox lung tumors showing similar histopathological characteristics of advanced adenocarcinoma, including pleomorphic nuclei and rare giant cells.
