Establishment and Characterization of JHUCS-1 Cell line Derived from Carcinosarcoma of the Human Uterus

Authors


Abstract

Abstract  The cell line designed JHUCS-1 was established from a carcinosarcoma (malignant mixed mesodermal tumor) of the uterus that was surgically removed from a 57-year-old Japanese woman. We carefully examined the histopathology of the original tumor after the cell line was established and noted differentiation into a neuroendocrine carcinoma within the tumor's epithelial components. Immunohistochemical staining of the tumorous tissue that had been heterotransplanted was positive for Leu7. Additionally, secretary granules were observed in the grafted cells as determined by electron microscopy. These results support the existence of neuroendocrine cells within the JHUCS-1 cell line.
