摘要The SGC-7901 gastric adenocarcinoma cell line is established. It is cultured from material obtained from metastasized lymph nodes on the gastric lesser curvature in a female patient. The cell line re produces continuously every 7 days. Polygonal and epithelioid cells account for 95.2% of the cell population. There is marked poikilocytosis. The chromosome modal number is 67, constituting 42% of the karyotyped cells. Chromosome aberration is observed in 6% of the cases. Percentage of secondary tumor growth is high by animal inoculation. Both the cultured cells and those of the primary tumor were PAS positive and Accian blue negative. Transmission electron microscopy (TEM) revealed microvilli over the cell surface and intracellular secretory granules; multiple intercellular junctional and inlay structures were also demonstrated.
