Note on the ultrastructure of the Guérin T-8 transplantable tumour.

Abstract

The ultrastructure of the Guérin tumour T-8 is described. Although this transplantable tumour has its ancestry in an uterine adenocarcinoma, there is no more evidence of gland formation. Desmosomes, or any other form of cell attachment organelle, were totally absent. The tumour has now a very anaplastic sarcomatous appearance.
