Heterotransplantation of human basal cell carcinomas in "nude" mice.
Human basal cell carcinomas, obtained from 10 subjects were transplanted to 25 "nude" mice. Two methods of transplantation were used and compared. Grafting gave better results than subcutaneous implantation. Tumor cells were identified in 5 mice, however only 2 of them developed lesions with histology similar to human basal cell carcinoma. Grafts, in which tumors developed, were obtained from superficial basal cell carcinoma. No reasons for the cause of the low percentage of successful transplantation and slow rates of growth of the transplants are found; however, possible immunological, vascular and environmental factors are discussed.
