Gastric mucosa of a monkey.
This field shows the region of the pits at the surface of the mucosa. One pit opens into two gastric glands (arrows). The pits are lined with a simple columnar epithelium composed exclusively of surface mucous cells (*). The isthmuses of the glands are lined with undifferentiated epithelial cells (+). These cells divide, undergo renewal and give rise to surface mucous cells, which migrate up to the surface of the mucosa. They also differentiate into parietal cells and mucous neck cells, which migrate toward the base of the glands. Stain: H–E
