Zusammenfassung

Zahlreiche Untersuchungsmethoden von Kopf-und Halstumoren sind nur mit Hilfe von oft großen Mengen reiner Tumorzellen möglich. Insbesondere biochemische und immunologische Verfahren verbieten nicht selten eine Verunreinigung der experimentellen Ansätze durch Nicht-Tumorzellen.

Reine Tumorzellen eines Larynxkarzinoms und eines Submandibulariskarzinoms mit nachgewiesener maligner Potenz wurden bisher jedoch noch nicht dargestellt. In der vorliegenden Untersuchung gelang es, aus einem Larynxsowie aus einem Submandibulariskarzinom Malignomzellen in Reinform zu züchten. Nach Auswachsen einer gemischten Zellpopulation konnten Einzelzellen präpariert und vermehrt werden. Zum Nachweis der Malignität wurden die reinen Zellinien auf immundefiziente (abwehrgeschwächte) Mäuse transplantiert. Es entstanden Karzinome, welche den ursprünglichen Tumoren histologisch entsprachen.

Summary

For many techniques in the oncology of head and neck tumors large amounts of pure tumor cells are required.

Although larynx and salivary gland tumors are common in man, no report exists on isolation and purification of tumor cells of which malignancy was proved.

The present paper describes in vitro cultivation of living human malignant tumor cells from a larynx and a submandibular gland carcinoma. Carcinoma cells were freed from all non-tumor cells and cloned thus indicating that cultures contained only a single cell type. Transplantation of grown cells s.c. into athymic (nu/nu) mice induced rapidly growing tumors of which malignancy was demonstrated by histology.
