Establishment and immunohistochemical characterization of an experimentally induced transplantable malignant schwannoma in the rat and two derived cell lines.

Abstract excerpt

Oral administration of N-methyl-N'-nitro-N-nitrosoguanidine induced gastrointestinal tumors in 15 out of 19 rats: six adenomas, seven adenocarcinomas, one fibrosarcoma and one malignant schwannoma that was homotransplantable. Both the original and transplantable tumor exhibited characteristic morphological features and immunoreactivity identical to that of a human malignant schwannoma: positive reaction for S-100...
