Unicellular gland
This electron micrograph shows the apex of a goblet cell filled with mucin granules. The goblet cell is flanked by non-secretory, ciliated cells of the respiratory epithelium. The mucin granules contain highly glycosylated proteins which become hydrated after release, thereby forming mucus. 14,000x
