该协议描述了使用切除的肠组织制剂或"肠囊"作为肠道屏障功能的离体模型。该模型可用于评估消化疾病动物模型中特定肠道部位的上皮屏障和粘液凝胶层的完整性。

该程序的总体目标是评估胃肠道疾病动物模型中的局部肠道完整性。这种方法可以帮助回答有关胃肠道疾病的关键问题,例如肌膜完整性是否丧失,或者在疾病期间特定分子或细菌的摄取是否增加。该技术的主要优点是可用于评估胃肠道内的特定区域。为了准备胃肠道,首先用 70% 乙醇喷洒小鼠的腹部和胸部,然后用剪刀在腹部中间做一个水平切口,露出腹膜。接下来,在幽门括约肌处从胃中切下上小肠,在肛缘处切开大肠。然后用镊子轻轻取出肠系膜,将肠道放入预热的氧化培养基中。确定要评估通透性的区域,在结肠和髂骨相对于盲肠的切片中测量十二指肠和空肠相对于胃的切片,以保持实验动物之间的一致性。注意粘膜相关淋巴组织的存在,例如 Peyer 斑,可以识别为管腔沙罗侧的小结节。然后,切开选定的切片,并使用 1 ml 注射器轻轻将段的管腔内容物冲洗到含有 37 的培养皿中
