摘要

目的探讨长爪沙鼠胃肠道Cajal间质细胞（ICCs）的形态和分布规律。方法采用10只成年长爪沙鼠，体重50~70g，取胃、小肠、结肠制作冷冻切片，结合全层铺片的c-Kit免疫荧光染色。结果 ICCs呈网络状分布于整个胃肠道，不同部位ICCs的分布及形态有所不同。在胃底部，仅见肌内ICCs(ICC-IM），而在胃体和胃窦部除ICC-IM外，可见肌间ICCs(ICC-MY)分布在肌间神经丛周围；其细胞密度胃底ICC-IM最多，由胃底至胃窦逐渐减少，而ICC-MY由胃体至胃窦逐渐增多。在小肠可见ICC-IM, ICC-MY和深肌层ICCs(ICC-DMP)3个亚群，结肠管壁内也分布有ICC-IM、ICC-MY和黏膜下ICCs(ICC-SM)3个亚群。结论沙鼠可用于有关ICCs正常形态、结构及功能的研究。

Abstract

Objective To observe the distribution and morphological features of interstitial cells of Cajal (ICCs) in the gastrointestinal (GI) tract of Mongolian gerbil. Methods Whole GI tracts, including stomach, small and large intestines of ten adult Mongolian gerbils were removed and performed for C-kit immunocytochemical staining with whole-mount preparations and cryo-sections. Results c-Kit positive immunoreactivity cells distributed along the entire GI tract. Intramuscular ICC(ICC-IM) cells were only in the fundus of the stomach.Myenteric ICC(ICC-MY) profiels were encountered between the longitudinal and circular muscle layers of the corpus and antrum of the stomach. The density of ICC-IM profiels gradually decreased from the fundus to the antrum. Whereas, ICC-MY profiels gradually increased from the corpus to the antrum. In the small intestine, ICCs were often observed in three regions, i.e. deep muscular plexus ICC(ICC-DMP), ICC-IM and ICC-MY. While in the colon, ICCs were seen as ICC-IM, ICC-MY and Swbmucosal ICC(ICC-SM). Conclusion Mongolian gerbil may be used to research the morphology and function of ICCs.
