Abstract: | Summary In antral mucosa of the mouse stomach, the volume of mucus in mucous cells was measured morphometrically to determine whether this value changes during cell migration from the base of the pit to the surface. Both the volume density of mucous granules (the fraction of cell volume occupied by the granules) and the volume of intracellular mucus were reduced to about half in surface cells compared with those of upper pit cells. This indicates that mucus secretion is substantial during the later part of the lifespan of these cells, and is not due simply to the shedding of senescent cells.Supported by a grant from the National Health and Medical Research Council |
