嗅神经母细胞瘤是一种罕见的嗅黏膜恶性肿瘤,可能起源于嗅上皮。为了确定这种肿瘤的特征,我们在存在或不存在影响嗅觉组织的生长因子(转化生长因子α和碱性成纤维细胞生长因子)的情况下培养嗅神经母细胞瘤细胞,并通过测量细胞内钙的变化来评估它们对已知气味的反应。未经处理的细胞对气味没有反应。碱性成纤维细胞生长因子处理有细胞毒性作用,处理后的细胞对气味没有反应。转化生长因子α处理可诱导这些细胞产生气味反应。细胞对100 nm到100μM浓度的气味有反应,细胞内钙的增加和减少都有反应。细胞内钙的增加是由钙内流调节的,并被已知抑制嗅觉感受器神经元第二信使通路的化合物可逆地阻断。因此,嗅神经母细胞瘤细胞的钙反应是气味所特有的,与嗅觉感受器神经元的反应相似。这些结果支持嗅神经母细胞瘤细胞可能来自嗅觉的观点,因此它们可以作为研究人类嗅觉的模型细胞系。
Olfactory neuroblastoma is a rare malignancy of the olfactory mucosa that may be derived from the olfactory epithelium. To characterize this tumor, we cultured olfactory neuroblastoma cells in the presence or absence of growth factors (transforming growth factor α and basic fibroblast growth factor) known to affect olfactory tissue and assessed their responsiveness to known odorants by measuring changes in intracellular calcium. Untreated cells did not respond to odorants. Basic fibroblast growth factor treatment had cytotoxic effects, and treated cells did not respond to odorants. Transforming growth factor α treatment resulted in the induction of odor responsiveness in these cells. Cells responded to odorants at 100nM to 100μM concentrations and responded with both increases and decreases in intracellular calcium. Increases in intracellular calcium were mediated by a calcium influx and were reversibly blocked by compounds known to inhibit second messenger pathways in olfactory receptor neurons. The calcium responses of the olfactory neuroblastoma cells were thus specific to the odorants and similar to those found in olfactory receptor neurons. The results support the notion that olfactory neuroblastoma cells may be of olfactory origin and thus they can be used as a model cell line to study human olfaction.
