支气管类癌的细胞结构。

Postgrad Med J. 1977 Jul;53(621):360-3. doi: 10.1136/pgmj.53.621.360.

A histological and electronmicroscopic study of bronchial carcinoids indicated that these tumours are argyrophilic in keeping with their occurrence in tissue of embryologically foregut origin. Normal bronchi contain cells that resemble, in their electronmicroscopic content, intestinal Kultschitzky-type cells. Characteristic of the carcinoid cell is the presence of intracellular neurosecretory granules seen on electronmicroscopy despite the apparent absence of argentaffin granules under light microscopy.

一项关于支气管类癌的组织学和电子显微镜研究表明，这些肿瘤是嗜银性的，这与它们发生于胚胎前肠起源的组织一致。正常支气管含有在电子显微镜下其内容物类似于肠道库尔奇茨基氏（Kultschitzky）型细胞的细胞。类癌细胞的特征是在电子显微镜下可见细胞内神经分泌颗粒，尽管在光学显微镜下明显没有嗜银颗粒。
