title: The suitability of immunosuppressed mice kept in a standard animal unit as recipients of human tumour xenografts.
abstract: CBA/Lac mice were immunosuppressed by thymectomy and whole body irradiation with 250 kVp X-rays following pretreatment with cytosine arabinoside. The optimum radiation dose for immunosuppression with prolonged survival was 7.35 Gy. The animals were kept in a standard animal unit with an overall survival rate of 83%. They were found to be suitable for large scale, long-term, xenotransplantation experiments at 20% of the cost of nude mice.
