Heterotransplantation of equine carcinoma cells in athymic (nude) mice. 1986

L L Pardini, and L M Aaronson, and P L Hering, and R S Pardini

Nondifferentiated equine carcinoma cells from a primary lesion were implanted subcutaneously in athymic (nude) mice. The cells were implanted at 2 sites each in 3 mice. At 1 of the 6 inoculation sites, a tumor developed, which invaded surrounding tissues, as shown by histopathologic examination. Karyotype analysis verified that the tumor was of equine origin. Cells from this tumor were serially heterotransplanted 20 times without change in growth rate. Once established in nude mice, this equine carcinoma cell line was stored cryogenically and then was successfully reimplanted into nude mice. All of the implants developed into tumors, over 20 generations. Preliminary screening of antineoplastic drugs indicated that this tumor line is sensitive to cyclophosphamide. Because of its ease of handling and high reimplantation efficiency, this tumor line should prove useful in equine cancer research.
