Electron microscopic observations of surface mucous cells in the mouse gastric mucosa during physiological degeneration and extrusion.


The gastric mucosa of adult mice was observed by electron microscopy, and the following findings were obtained. Surface mucous cells mostly undergo degeneration in situ before extrusion from the mucosal surface. Degenerating cells exhibit low electron density of the cytoplasmic matrix and interchromatin region of the nucleus. Some vacuoles can be seen in… (More)
