CIL (2012) CIL:38923, globlet cell. CIL. Dataset

Colorized transmission electron micrograph of goblet cells packed full of mucous globules (blue). The cells release the globules to provide lubrication and protection to the inner surfaces of the intestine and the respiratory system among others. The mucous globules are condensed inside the goblet cell but expand hugely once they are released, absorbing water within 20 milliseconds. This rapid release occurs in response to lots of different stimuli and allows the mucous to work instantly. The horizontal field width of the sample is 17.3 micrometers.

着色透射电子显微镜下的杯状细胞，细胞内充满粘液球体（蓝色）。细胞释放粘液球体以提供润滑和保护，作用于小肠及呼吸系统等内部表面。粘液球体在杯状细胞内呈凝聚状态，但一旦释放，会急剧膨胀，并在20毫秒内吸收水分。这种快速的释放是对多种不同刺激的反应，使得粘液能够即时发挥作用。样本的水平视野宽度为17.3微米。
