Abstract

Tissue reconstruction of various kinds of gynecologic malignant tumor cell lines was studied using the rotation-culture system. The reconstructed cell aggregates were examined histologically using both light and electron microscopy. Our established cell lines used in this study were uterine cervical epidermoid carcinoma, endometrial adenocarcinoma, ovarian malignant tumor and uterine sarcoma. All of the reconstructed aggregates from each cell line were very similar to the original tumor tissue. In the case of a well differentiated type of adenocarcinoma derived from the ovarian cancers or the endometrial cancers, papillary cell aggregates (grape-like structures) and/or hollow cell ball (gland alveolus-like) structures were observed. The individual cells were adjoined with by desmosomes and well developed microvilli protruded from the free surface of the cells. On the other hand large cell non-keratinizing squamous cell carcinoma cells formed spherical-shaped aggregates that showed a stratified structure similar to pearl formation. Sarcoma cells formed solid clusters while desmosomes or desmosome-like junctions were not detected. Rotation culture is an excellent method to reveal diagnosis of the original tumor and tumorigenesis ...Continue Reading
