title: [Morphologic and tumor-marker studies of human planocellular carcinoma of the bronchi in xenografts].
abstract: Authors have studied the morphology of 10 human planocellular bronchus carcinoma xenografts parallel with that of the donor tumour. The expression of cytokeratin, epithelial membrane antigen and carcinoembryonic tumour markers was also studied and compared. The histological structure and marker expression of xenografts did not change as compared to the donor tissue. Tumour cells were characterized by cytokeratin rather than epithelial membrane antigen. Carcinoembryonic antigen positivity occurred mainly in well-differentiated tumours. The cellular heterogeneity of human planocellular bronchus carcinomas was found to occur also in xenograft tumours.
