Growth suppression of subcutaneously inoculated hepatic tumors after injection of syngeneic liver cells into the subcutaneous tissue of rats.

One week after the sc injection of minced tissues of the livers, kidneys, or spleens of W, Donryu, and MP rats into the left back of syngeneic rats, ascites-type tumor cells derived from rat hepatoma (AH 130) or Walker carcinosarcoma cells derived from rat breast tumor were inoculated sc into the right back. Ascites hepatoma cell growth was slowest in the group given the liver preparation, whereas no significant difference was noted in the growth of Walker carcinosarcoma in all groups. The results were similar in all strains.
