We established a novel cancer cell line (MAST) from the ascitic fluid of a metastatic infiltrating ductal carcinoma of the breast. The epithelial and neoplastic nature of the MAST cells was confirmed by ultrastructural analysis. The cell line was maintained as a monolayer with a doubling time of about 68 h, and it possessed an abnormal karyotype with a modal chromosome number of 60, a trisomy of chromosome 18 and other unidentified rearranged chromosomes. Among the markers consistently found in MAST metaphases, we noted a t(14; 14) and a very large subtelocentric, a large satellited acrocentric and a very large submetacentric chromosome with striking fluorescent bands. Immunoenzymatic assay demonstrated that the MAST cell line was positive for estrogen and progesterone receptors. The in vitro drug-sensitivity assay showed a marked resistance of the cell line to 5-fluorouracil and 4-hydroperoxycyclophosphamide and a moderate resistance to etoposide and 4'-epidoxorubicin. The molecular analysis showed a four-to sixfold amplification of the c-myc gene and no amplification or rearrangement of the int-2, c-erbB-2, c-Ha-ras, c-mos and hst-1 genes.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
