Aim: To study gastric sections with a fluorescent microscope in a cohort of baboons. Material and Methods: Gastric sections from 38 baboons were stained with hematoxylin-eosin (H&E) and examined in a fluorescence microscope (FLM). The thickness of the parietal cell population was assessed at ×10 magnification. Results: H&E stained all mucosal cells: fovelar, parietal and chief cells. When the same sections were analyzed with an FLM, only parietal cells were auto-fluorescent, whereas fovelar and chief cells remained non-fluorescent. Parietal cells formed a distinct, continuous auto-fluorescent band. The ratio of the auto-fluorescent parietal cell band/total mucosa ranged between 0.20 and 0.30. Conclusion: Gastric parietal cells became auto-fluorescent when H&E-stained sections from baboon stomachs were observed with an FLM. Eosin was the stain responsible for this optical phenomenon. ER -
