Heterotransplantation of human pleomorphic adenomas to nude mice

The purpose of the present study was to establish a model for in vivo studies of human pleomorphic adenomas by heterotransplantation of tumour tissue to nude mice. Tissue from 7 tumours was transplanted to a total of 34 mice. Take with obvious growth occurred in 12 mice, and survival of the tissue was seen in an additional 8 mice. The overall histological picture was unchanged from the donor tumours to the transplanted tissue. The possibilities of the model are discussed.
