Figure 5. Early weaning and corticosterone change the number of mucin 6- secreting cells.

Mucin 6 was scarcely identified in the gastric mucosa of suckling rats (immunohistochemistry developed with DAB+ H₂O₂ and counterstained with Mayer’s Hematoxylin), and synthesis increased after EW both in pups and young adults (A). Original magnification: X100. Granules containing mucin 6 can be detected in the cytoplasm of mature MNC (B) (original magnification at X100 and digital zoom were used). Labeling index (%) is represented as means ± S.E.M. (C). (n) = 3–4 for each group. *P < 0.05 and ***P < 0.001 after one-tailed Student t test for dietary condition or RU486 treatment.
