[Morphological studies on cellfree induced sarcomas in syrian hamster (author's transl)]

Morphological studies on sarcomas induced in syrian hamsters by cellfree transmission are described. The tumour tissue for the cellfree preparations stemmed from a sarcoma, containing C-particles. Basically, three histological groups have been distinguished: 1. neoplasms of the peripheral nerve-sheath, 2. undifferentiated sarcomas, and 3. liposarcomas. Furthermore, a rhabdomyosarcoma, an angiosarcoma and, in a heterotransfection on rat, an osteosarcoma have been established. The great majority of tumours could be transmitted by cellfree preparations. To this neoplasms belong the undifferentiated histological structure.
