The NCI-N87 epithelial cell line was originally established from the stomach tissue of a male patient with gastric carcinoma. They are extracted from the metastatic site located in the liver. The NCI-N87 cells test positive for myc and ERRBB2 oncogenes, express carcinoembryonic antigen (CEA), receptors for muscarinic cholinergic agents and TAG 72 surface glycoproteins.
