Abstract
A new continuous cell line from a human malignant carcinoid of the sma ll intestine (KRJ-I) was established. The cells showed morphological a nd immunocytochemical features of the tumor of origin and expressed es trogen receptors. The cells are growing as a suspension, forming multi cellular aggregates and spheroids. Electron microscopy confirmed the p resence of neuroendocrine granules. Dose-dependent growth inhibition w as observed after incubation with 5-azacytidine. Cytogenetic analyses of the tumor of origin, the cell line KRJ-I and a liver metastasis KRJ -II revealed clonal tetraploidy and clonal loss of the Y-chromosome an d chromosome 19.
