TFF2 is expressed in mucous neck cells
, pyloric glands, and Brunner's glands, while intestinal trefoil factor (TFF3) is mainly expressed in goblet cells of the small and large intestines (Hoffmann et al., 2001).
The gastric glands are composed of five cell types, including the chief cells, parietal cells, mucous neck cells, enteroendocrine cells, and undifferentiated adult stem cells.
Mucous neck cells: Mucous cells can be detected at the 13th week for the first time.
The gastric glands occupied all the la- mina propria and consisted of mucous neck cells
, parietal cells and chief cells.
The mucous neck cells at many places look distorted and are seen merging with each other.
The mucous neck cells are degenerated and there nuclei are not seen.
At the upper part of the mucosal layer ([less than or equal to] 60 [micro]m), MPM images of cardiac mucosa displayed columnar foveolar gastric mucous neck cells with approximately uniform size and shape (Figure 3, A and B).
Although mucin in gastric foveolar mucous neck cells also has less fluorescent signal, it consists of many small round mucin vacuoles, which are less dark than mucin vacuoles of goblet cells.
Comparative histochemical study of alimentary tracts with special reference to the mucous neck cells
of the stomach.
The mucous neck cells distributed in the neck of glands.
The former was the most dense, lined up outside of the main and mucous neck cells. A portion of some glands was mainly covered with parietal cells, which decreased gradually at the bottom, Whereas, it significantly reduced in the blind end.
In contrast, MUC5AC distribution is limited to cytoplasm of the surface and foveolar epithelium and mucous neck cells
throughout the stomach.
