Clonal origin of metastatic testicular teratomas.
PURPOSE Testicular teratomas in adult patients are histologically diverse tumors that frequently coexist with other germ cell tumor (GCT) components. These mixed GCTs often metastasize to retroperitoneal lymph nodes where multiple GCT elements are frequently present in the same metastatic lesion. Neither the genetic relationships among the different components in metastatic lesions nor the rela...

Mutant mice deficient in glucose-6-phosphate dehydrogenase were used to induce teratomas. This enzyme is linked to the X chromosome, which can be inactivated in female embryo. The differences in the enzyme activity between yolk sac mesoderm and embryo versus yolk sac endoderm can be detected in female concepti by using appropriate crosses of wild-type and G6PD-deficient mice.

متن کاملBilateral ovarian teratomas in a mouse.

In @,000autopsies on mice, Slye, Holmes, and Wells (1@) found only 46 with solid tumors of the ovary, and of these only one was a teratoma.

متن کاملThe Relationship of Twins, Teratomas, and Ovarian Dermoids
The bizarre structure of teratomatous tumors has long excited interest. Unlike other neoplasms, the teratomas are composed, characteristically, of more than a single type of cell and are related, histogenetically, to more than one of the three embryonic germ layers. The constituent elements of these tumors may be quite foreign to their site of origin in the body and, in their arrangement, tend ...
