The result showed that the surface of highly pulmonary adenocarcinoma cells is covered with irregular microvilli and poorly differentiated adenocarcinoma cells is covered with irregular microfoldings.

Results CK19 was detectable in suprabasal cell layers in epithelial dysplasia and in oral cancer, especially in poor differentiated cancerous cells.

We have obtained foci of transformed NIH3T3 cells through transfection of human DNA from CNE-2 (an undifferentiated epithelial cell line of nasopharyngeal carcinoma).
