Summary

The authors describe an experimental study on rabbits whereby the development of sarcomas was induced following injection into the knee joint with 9-10-dimethyl-1-2-benzanthracene.

The results of the experiment are in contrast to those of other authors as no “synovialoma” or synovial sarcoma developed but only morphological patterns which might belong to malignant fibrous histiocytoma and occasionally fibrosarcoma.

In accord with our results the hypothesis is discussed that all malignant mesenchymal neoplasias result from a not clearly identifiable pluripotent mesenchymal stem cell.

Zusammenfassung

Die Autoren berichten über eine experimentelle Studie mit Kaninchen, bei denen nach intraarticulären Injektionen mit 9-10-Dimethyl-1-2-Benzanthracen ins Kniegelenk die Entwicklung von Sarkomen induziert werden soll.

Über die Ergebnisse dieser Versuche wird berichtet. Im Gegensatz zu anderen Autoren entstanden keine “Synovialome” bzw. Synovialsarkome, sondern nur solche, die vornehmlich den malignen fibrösen Histizytomen sowie ganz vereinzelt den Fibrosarkomen zuzurechnen sind.

Im Einklang mit den Ergebnissen wird auf die Hypothese, daß alle malignen mesenchymalen Neoplasien aus einer bisher noch nicht eindeutig identifizierten pluripotenten mesenchymalen Stammzelle hervorgehen, eingegangen.
