Gastric surface epithelial cells (SEC) from fed rats, from rats fasted for 16 h and from mucosae exposed in an ex-vivo chamber to 16 mM aspirin for 5 min were examined by transmission electron microscopy. SEC have the capability to phagocytose adjacent epithelial cells and parietal cells. Phagocytosis is rare in mucosae from fasted animals but common in fed animals or after brief exposure to aspirin. Phagocytic capabilities are not restricted to the progenitor zone but exist throughout the surface epithelium. Phagocytosis may provide a mechanism for the removal of damaged or senescent cells from the surface epithelium.
通过透射电子显微镜检查了来自喂食大鼠、禁食16小时的大鼠以及在体外腔室中暴露于16 mM阿司匹林5分钟的黏膜的胃表面上皮细胞（SEC）。SEC具有吞噬相邻上皮细胞和壁细胞的能力。在禁食动物的黏膜中吞噬作用很少见，但在喂食动物或短暂接触阿司匹林后很常见。吞噬能力不限于祖细胞区，而是存在于整个表面上皮中。吞噬作用可能为从表面上皮中清除受损或衰老细胞提供一种机制。
