Three human gastric cancer cell lines, NU-GC-2, NU-GC-3 and NU-GC-4 were established in vitro from the cancer tissues obtained from 3 patients during surgery. The pathological findings of the gastric tumors of these cases revealed poorly differentiated adenocarcinoma (and partial signet-ring cell carcinoma in the case of NU-GC-4). NU-GC-2 and NU-GC-4 were originally obtained from metastatic paragastric lymph nodes and NU-GC-3 was obtained from a metastatic tumor in the brachial muscle. The cells of NU-GC-2 and NU-GC-3 are polygonal in shape and grow as a monolayer sheet. NU-GC-4 cells, however, are mainly spherical in shape with a few free floating cells. Electron microscopy revealed epithelial characteristics in all 3 cell lines. The average doubling time of NU-GC-2 was 36.1 hours, that of NU-GC-3 was 38.2 hours and that of NU-GC-4 was 29.9 hours. The modal chromosome number of NU-GC-2 was 62, that of NU-GC-3 was 58 and those of NU-GC-4 grown in in vitro and in vivo were 52-54 and 53, respectively. In vitro and in vivo lines of NU-GC-4 were established from the same tumor. These two cell lines are quite similar in morphology, but slightly different in karyotype. The in vitro sensitivity to anticancer agents was highest in NU-GC-4 and lowest in NU-GC-2. Of the anticancer agents, mitomycin C and adriamycin were most effective on the cells of all 3 cell lines.
