Testis carcinoma: transplantation into nude mice
National Cancer Institute Monograph
|December 1, 1978
Summary
Human testis tumor cell lines (tera-1 and tera-2) were successfully grown in nude mice. Fresh tumor material did not yield growth, aiding in cell line characterization.
Area of Science:
- Oncology
- Transplantation Biology
Background:
- Human testis tumors are a significant area of oncological research.
- Established cell lines are crucial for preclinical cancer studies.
Purpose of the Study:
- To evaluate the heterotransplantation potential of human testis tumors and established cell lines in nude mice.
- To characterize the in vivo growth of tera-1 and tera-2 cell lines.
Main Methods:
- Heterotransplantation of primary and secondary human testis tumors into nude mice.
- Heterotransplantation of tera-1 and tera-2 cell lines into nude mice.
- Subcutaneous and anterior chamber of the eye implantation sites were utilized.
Main Results:
- Established cell lines (tera-1 and tera-2) demonstrated successful growth in nude mice without additional immunosuppression.
- Tumor cells grew both subcutaneously and in the anterior chamber of the eye.
- Fresh human testis tumor material did not achieve growth in the experimental model.
Conclusions:
- The established tera-1 and tera-2 cell lines are viable models for in vivo studies of human testis tumors.
- The lack of growth from fresh tumor material highlights the challenges in xenografting primary tumor samples.
- Successful xenografting of cell lines aids in their further characterization and utility in cancer research.
