Establishment and characterization of a cell line, MT-213-VGH, isolated from a mixed müllerian tumor of the uterus.

ABSTRACT

OBJECTIVE: To establish a cell line from a woman with malignant mixed müllerian tumor of the uterus and to examine the biologic properties of this cell line (MT-213-VGH). STUDY DESIGN: Cells were cloned by the limiting dilution method. Histologic staining of mixed müllerian (mesodermal) tumor (MMMT) cells was performed with May-Grünwald-Giemsa and hematoxylin and eosin stain. After more than 20 passages, cells were used to estimate the population-doubling time and colony-forming efficiency of MMMT cells. The cell line exhibited considerable variation in the degree of sensitivity to diverse chemotherapy drugs in vitro. RESULTS: MMMT cells containing antigens for vimentin and myoglobin were detected, but those for CA-125, carcinoembryonic antigen, cytoskeleton, desmin, epithelial membrane antigen and fibronectin were not found. In addition, MT-213-VGH cells contained a mucinous substance; its chromosome model number is 45. This cell line showed differential sensitivities to chemotherapeutic agents, such as bleomycin, cisplatin, 5-fluorouracil and vinblastine. CONCLUSION: The establishment and availability of the number cell line MT-213-VGH for a malignant mixed müllerian tumor of the uterus should assist in research on new methods of managing this type of gynecologic cancer.
