| Abstract: | Mammary gland tumors arising in factorless C3Hf mice, if transplanted into MTV-S+ and MTV-S– recipients, were found to grow at the same rate and early thymectomy likewise had no effect on their growth. The more rapid growth of transplanted tumors in MTV-S+ than in MTV-S– recipients after transplantation of mammary gland tumors from C3H/He mice and the inhibition of tumor growth after early thymectomy are evidently connected with special features of the immunological reaction to virus-induced antigens.Institute of Cytology and Genetics, Academy of Sciences of the USSR, Siberian Branch, Novosibirsk.
