Abstract
In several studies, numerous microvilli were found on the surfaces of malignant tumor cells which had high growth potentials, and some tumor-related antigens were identified on these microvilli. Transferrin receptor (TfR) is expressed in proliferating cells and regarded as a tumor marker. In human carcinoma cell lines (HeLa cells, KB cells, and HSC-7 cells), significantly more microvilli were observed in the subconfluent phase than in the confluent phase. Also, TfR was found along the plasma membranes, especially well developed microvilli, coated pits, and coated vesicles in both phases by the immunoelectron microscopic method. These results indicate that the proliferative ability of the tumor cells might correlate with the development of microvilli.
