| Abstract: | Heterotransplantation of gastric adenocarcinoma, induced in dog by N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG) has been attempted to nude mouse. Biopsied materials from Borrmann 3 type carcinoma, which showed signet-ring cell carcinoma at the subcardiac region of a beagle dog, were inoculated into the muscles of the hind legs of BALB/c-nu/nu nude mice. Serial transmission was obtained in 2 lives, so far 4-5 passages. The histological findings of the grafts were mainly poorly differentiated adenocarcinomas. |
