Testis carcinoma: transplantation into nude mice.

Heterotransplantation of primary and secondary human testis tumors and the established cell lines, tera-1 and tera-2, into nude mice has been performed. The cell lines have been successfully grown subcutaneously and in the anterior chamber of the eye, without further immunosuppression, and this has contributed to the characterization of the lines. Growth has not been obtained with the fresh tumor material.
