A new continuous cell line, GOTO, has been established in tissue culture from a human neuroblastoma arising from the adrenal and maintained for 5 years. The cells are small and fibroblast-like, and grow in dense layer. Population doubling time was approximately 48 hr. The modal chromosome number was near-diploid. Neither marker chromosomes nor double-minute chromosomes were abserved. Inoculum of 10(7) cells produced tumors in ATS-treated hamsters and athymic nude mice, and the histological appearance of tumors was consistent with undifferentiated neuroblastoma. Neural features of the cells were also confirmed by ultrastructural examination. Biochemical analysis showed this cell line to be cholinergic. Morphological differentiation leading to neurite formation was induced by cultivation in serum-free medium.
一种新的连续细胞系GOTO已通过组织培养从肾上腺来源的人类神经母细胞瘤中建立,并维持了5年。细胞体积小,呈成纤维细胞样,以致密层生长。群体倍增时间约为48小时。众数染色体数接近二倍体。未观察到标记染色体和双微小染色体。接种10(7)个细胞可在经ATS处理的仓鼠和无胸腺裸鼠中产生肿瘤,肿瘤的组织学表现与未分化神经母细胞瘤一致。细胞的神经特征也通过超微结构检查得到证实。生化分析表明该细胞系具有胆碱能特性。在无血清培养基中培养可诱导导致神经突形成的形态学分化。
