Cellular transmission of canine lymphoma and leukemia in beagles.
Thirty-four neonatal beagles were inoculated with cells obtained originally from 2 adult beagles, 1 with lymphocytic leukemia, the other with generalized malignant lymphoma. Most of the puppies were irradiated before inoculation; a few were inoculated in utero and were not irradiated. Of the 11 puppies inoculated with buffy coat cells of the blood from the leukemic donor, 2 developed leukemia. Of the 23 pups inoculated with cells of lymph nodes from the spontaneous lymphoma or positive passages, 13 developed lymphoma. Time of measurable onset of leukemia or lymphoma in the recipients varied from 12-60 days after inoculation. One passage was achieved with the leukemia and three serial passages with the lymphoma. A female karyotype was obtained from a neoplastic lymph node in a male recipient of the lymphoma. Since the donor was female, this suggests that the passages of the lymphoma were transplants.
