Abstract

Tumour cells from a hepatic metastasis of a midgut carcinoid tumour were studied during 240 days of culture. A cell line could not be established, but the cells regularly formed large clusters and islets. The spontaneous release of serotonin (5-HT) and neuropeptide K-like immunoreactivity from cultures were followed. The amine and the peptide levels were unstable without evident covariation. The response to stimulation with noradrenaline and isoprenaline was studied during the culture period. The tumour cells released 5-HT selectively at stimulation with isoprenaline. This responsiveness also showed considerable variation with long periods of quiescence. Ultrastructurally the tumour cells showed a certain degree of polarization with apical microvilli and a supranuclear Golgi apparatus. When studied by confocal laser scanning the tumour cells were demonstrated to be cylindrical in shape with a cytoplasmic attachment to the matrix.
