Mucous cells of human bronchial glands contain secretory granules with 5,5-7 nm parallel filaments. In contrast with the glycoproteic-rich mucous granules, filamentary granules exhibit weak reactivity with tannic acid, indicative of proteins. Exocytosis or discharge in glandular lumen are sometimes observed. These original granules may probably represent an additional component of fibrillar matrix in mucus.
人类支气管腺的黏液细胞含有带有5至5 - 7纳米平行细丝的分泌颗粒。与富含糖蛋白的黏液颗粒不同，丝状颗粒与鞣酸的反应较弱，表明含有蛋白质。有时可观察到这些颗粒向腺腔内的胞吐作用或释放。这些原始颗粒可能代表黏液中纤维状基质的一种额外成分。
