Interzelluläre Verbindungen beim Plattenepithelkarzinom der menschlichen Haut in der Gewebekultur

Summary A new medium was developed for tissue-culturing of the human squamous cell carcinoma of the skin. The morphology of the outgrowing tumour cells is described, particularly with regard to the projections of cell surface. There are 2 forms to be differentiated: one which is similar to the desmosomes of the normal epithelium of the skin, and one of intercellular connective strands. The different functions of both forms are discussed with regard to the exchange of cell matter.
